The main function of the mould oscillation deflection detection instrument is to detect the the mould oscillation table’s oscillation frequency, amplitude, deflection rate, phase, oscillation trajectory curve, etc. Through the detection and adjustment of the detection instrument, the mold moves along the outer arc of the continuous casting machine according to the given amplitude, frequency and waveform deflection characteristics. The actual oscillation parameters of the mold oscillation table during the operation and production process and the process parameters of the cast products cannot be effectively known without the data detection of the mold deflection detection instrument, so that the operator cannot adjust the mould’s production process parameters in real time according to the real- time situation of the on-site production. The continuous casting mold deflection detection instrument independently developed by our company is suitable for various molds such as slab, square billet, round billet and shaped billet. The system obtains the process parameters such as actual oscillation holographic parameters and negative slip amount of the oscillation table by effectively detecting the movement of the mold.

MLC-V235 Continuous Casting Mold Level Automatic Measurement System Overview The automatic control for the molten steel level of the mold is one of the key technologies of continuous casting production. It is very important to reduce the labor intensity of workers, improve production efficiency, improve the quality and output of casting billet, reduce overflow and breakout of steel and improve the management level of steelmaking and continuous casting. The molten steel is poured into the mold. In order to prevent overflow, the molten steel level must be kept stable. Otherwise, during the casting process, if the level will fluctuate too much, and slag will be involved, forming surface slag inclusion on the surface of the casting billet, affecting the quality of the billet. The test points out that the relationship between the level fluctuation and the depth of casting billet surface slag inclusion is as follows: The experience has shown that surface slag inclusions can be eliminated when the level fluctuation is within ±10mm. At the same time, if the level fluctuation is more than 10mm, the rate of longitudinal cracks on the casting billet surface is 30%. It means that the level fluctuation directly affects the surface quality of the casting billet. The principle of the system The eddy current type molten steel level gauge is the key to the system. The system operates reliably and has excellent performance: high temperature resistance, strong anti-interference ability, fast dynamic response (lag time <0.10s), high detection accuracy (<±05mm), and large measurement range (0-150mm). The selected electromagnetic field frequency ensures that the level detection probe only detects the level change of the mold and does not detect the mold flux or steel slag layer. The system has the advantages of simple operation and no radiation protection problems. The system is insensitive to argon blowing, and its sensors can be mounted on the tundish car or on the platform. The sensor is cooled by compressed air during use. The principle is shown in the figure A high-frequency exciting winding is installed above the molten steel surface of the mold. The magnetic field produced by exciting winding make induced eddy current appear. The magnetic field generated by the induced eddy current is in the opposite direction to the magnetic field generated by the high-frequency exciting winding, which changes the impedance of the high-frequency exciting winding. Under the condition that the winding material and structure, steel grade, temperature remain unchanged, the coil impedance change only has a single-value function relationship with the height of the molten steel level. As long as the impedance change of the high-frequency winding is detected, the change of the molten steel level in the mold can be converted. The components of the system Continuous casting mold level automatic control system is composed of eddy current tyoe molten steel level gauge, controller and digital actuator for adjusting the opening of tundish stopper. The detection end of the mold level automatic control system is ① eddy current displacement sensor, which uses the eddy current mutual inductance effect between the energized coil and the metal conductor to detect the distance. The effective signal of the eddy current sensor is amplified and linearized by the circuit of ② mold level gauge, which converts the 0-150mm change in the molten steel level of the mold into a standard signal of 4- 20mA.DC, and then transmits it to the ③ control computer to complete data processing and system control functions. We can also control the actuator manually and automatically through the ④on-site operation display control panel, and the opening of the stopper is controlled by the ⑤ actuator to realize the automatic control of the molten steel level. 1 Eddy current sensor; 2 mold level gauge; 3 control computer; 4 On-site operation display control panel; 5 digital actuator; The control principle of the system The system can be set to four control modes: automatic, semi-automatic, manual and motor clutch. The automatic mode is the closed-loop control system of the molten steel level, and control the opening of the stopper by the digital actuator; the semi-automatic mode uses opening degree setter and digital actuator to set the opening of the stopper manually; the manual mode is to open and close the button directly to control the opening of the stopper; the motor clutch mode is quickly changed from any of the above control methods to manual stopper operation. The functions of the system also include: display and record of molten steel level, nozzle opening and casting speed; setting of molten steel level and nozzle opening; alarm of molten steel level at limit value etc. In addition to taking the detection of molten steel level as the main feedback signal of the control system, the control system also considers various interference factors that have an impact on the level control. These interference factors include: 1. The influence of the change of the flow characteristics on the control system after the melt loss of the stopper 2. The influence of the weight change of molten steel in the tundish on the control system 3. The influence of the change of the casting speed of the continuous casting machine on the control system 4. The influence of the mold width change (the mold width is adjustable) on the control system 5. The influence of the vibration frequency and amplitude of the mold on the molten steel level gauge The function and software implementation In order to overcome these disturbances, the mold level control strategy adopts PID control. And on the basis of PID control, self-adaptive correction and feedforward control are introduced to form an advanced control system. The level control is the main loop, and there is a proportional gain of the main loop controller. According to the self- adaptive correction of the mold width change and feedforward compensation of casting speed, so as to further reduce and eliminate liquid level fluctuations caused by mold width adjustment and casting speed changes. In order to reduce the frequent action of the stopper, the system adopts the intergarting time change of the controller, and automatically selects a longer intergarting time when the molten steel level fluctuates lightly. And the system will choose a shorter intergrating time when molten steel level fluctuates greatly. Thereby, the fluctuation of the controlled object caused by the frequent action of the stopper rod is suppressed. In the signal processing of molten steel level gauge, an appropriate filtering link is added and the vibration frequency synchronous filter is used for filtering processing, which can overcome the interference of mold vibration frequency and amplitude variation.

WGS-L020 Flat Steel/Ribbon Iron Width Measuring System Overview Whether the width and thickness of the flat steel/ribbon iron width measurement device can meet the standard in the production process directly determines the quality of the flat steel/ribbon iron. How to carry out high- precision measurement of flat steel produced at high speed is the key technology to improve the production efficiency and quality of flat steel. The flat steel/ribbon iron high-speed width measuring system developed by our company can monitor the whole process of flat steel production in real time. It can be used for the on-line analysis, processing, display and function alarm for the detected parameters of the width and thickness. We can provide customers with professional solutions. The measuring principle of the system The device adopts industrial laser sensor, through the principle of laser triangulation reflection: the laser beam is amplified to form a laser line and projected onto the surface of the object to be measured, the reflected light passes through the high-quality optical system to be projected onto the imaging matrix. Then the distance (Z axis) from the sensor to the measured surface and position information (X axis) along the laser line can be got after calculating. By moving the measured object or sensor, a set of three-dimensional measured value can be obtained. When measuring, we need to install a laser measurement sensor device directly above and below the ribbon iron. When the ribbon iron passes through, the width distance from the left and right of the ribbon iron and the height distance from the sensor to the ribbon iron can be measured by laser scanning. The thickness of flat steel can be measured by two sensors up and down. The flat steel width measuring system is mainly composed of line laser measurement sensors, connectors, front-end data acquisition, operation station (workstation) and server, mechanical structure, cooling protection device, etc. These devices form an independent measurement and calculation network, and through the high-speed data measurement and calculation of the system to achieve the alarm control of the detection record.

LDC-X200 Laser Diameter Measurement System Overview The non-contact diameter measuring system, is mainly used in the measurement of the outer diameter of various wire rods, bars, wires and pipes. The system can detect the change of the diameter (outer diameter) of the measured object in real time under the high temperature state. The working principle The diameter measuring system takes the laser scanning method as an example. It adopts the probe imported from Japan, which can achieve an accuracy of plus or minus 2 microns in the range of 0.3 to 30 mm. The acquisition frequency reaches 2000 times/second. The probe uses a self-excited infrared light source, which overcomes the measurement problem in dim environments. It adopts the measurement method of pulse parallel light scanning, and has a strong ability to resist the jitter of the measured object. (As shown in Figure 1) Since the shaking frequency of the measured object is much smaller than the scanning frequency, when the measured object A moves in the shakeable area, the measurement result will be able to ensure its accuracy because the time it blocks the beam does not change. Figure 1: Probe Scanning Radiation Area The detection principle is as follows Figure 2: Working Principle First, the crystal oscillator generates self-excited high-frequency pulses, which are sent to the comparator and the stepping servo motor respectively. The stepping servo motor drives the octahedral prism to rotate at a high speed, and reflects the infrared laser emitted by the laser generator to the convex lens A. It becomes parallel light, and then collects on the photosensitive element C through the convex lens B in the infrared receiving probe. The photosensitive element C converts this signal into a corresponding electrical signal and sends it to the other end of the comparator to compare with the original signal. When there is no object to be measured in the measuring probe, the pulse signal at both ends of the comparator will be the same. Therefore, there is no difference output: when there is an object to be measured in the measuring probe, the photosensitive element C will output no pulse signal during the period of scanning through the object to be measured. Therefore, there will be a difference input for a period of time at both ends of the comparator, which corresponds to the diameter of the measured object. By calculating the oscillation period of the pulse and the length of the time slice without pulse, the diameter of the measured object can be known. The composition and functions of the system The system consists of the following main parts (as shown in Figure 1) 1. A measurement frame with four pairs of high-frequency laser scanning probes and non-contact infrared thermometers is installed 2. Four intelligent signal processors connected with four pairs of high frequency laser scanning probes 3. Cold air blowing system for cooling and cleaning the measuring frame 4.

LAG-S400 Infrared Converter Slag Detection System Overview The infrared converter slag detection system uses a far-infrared thermal imager to monitor the situation of converter tapping in real time, and is connected to the main control computer in the electrical room through the conversion and transmission of video signals. The radiation intensity in the infrared wavelength range of 7-14um is different to distinguish molten steel and slag. In the later stage of the converter tapping, the molten steel gradually decreases, and the steelmaking slag is involved in the molten steel and flows out of the tapping hole. After the thermal imager recognizes the steelmaking slag in the imaging temperature measurement, it will give an alarm according to the slag content ratio threshold set by the software. The thermal imager will start the slide plate to close the tapping hole, so as to realize the control of the slag in the converter tapping, and ensure the maximum yield of molten steel and the minimum control of the steelmaking slag content. The effect of slag detection in converter tapping is of great significance to the control effect of the slag amount. The converter slag detection and control system developed by our company conducts non-contact monitoring of the tapping steel flow through the far-infrared detector thermal imager. It can detect the slag condition in real time and output an alarm signal and control system, which can replace manual visual inspection and provide accurate, efficient and stable slag detection effect. When the system finds the slag, the intelligent control unit quickly makes a judgment of lifting the furnace and blocking the slag and outputs an alarm signal. As shown in Figure 1, the system includes thermal imager, front purge protection box, front electrical box, power distribution cabinet, main control monitor, monitor of rocking furnace chamber, sound and light alarm, infrared converter slag monitoring software system, etc. The features of thermal imager 1.

Overview: LGK-S107 analog heat source instrument (heating tool) is independently developed and designed by Wuhan CenterRise M&C CO.,. This instrument is a heating and testing equipment used to test the performance of the couple installed in the mold in continuous casting machine. After the installation of the mold breakout forecast couple is completed, the analog heat source instrument is used to test these couples before they go online. After the thermocouple is connected to the mold thermocouple detector, the current temperature of each thermocouple point will be displayed. By using our heating device to heat the copper plate point of each thermocouple at a fixed point, the thermocouple will have a synchronous temperature rise and then we can observe the temperature rise curve of the same column of temperature points to see whether the temperature measurement consistency of the column of couples is consistent, so as to judge the overall status of couples installed in the mold. If an abnormal point occurs, it needs to be repaired and replaced, so as to ensure the stable operation of the mold breakout prediction system. The working principle: The heating tool generates high heat by 220v alternating current and the electric heating element. The heat is transmitted to the copper plate of the mold through the copper head to simulate the heat source of molten steel, so that the thermocouples of the mold can sense the temperature change to achieve the purpose of calibrating the temperature measurement system.

Overview: Laser taper measuring instrument (multi-dimensional detection) is a new type of mold multi-taper measuring instrument developed by our company. The instrument adopts a high-precision, high-sensitivity laser measurement and positioning sensor, which scans the copper plate of the mold by a fixed- width laser line, and returns the measurement data in real time. The host computer shows the data of mold taper, surface cracks, surface flatness and other data after modeling and analyzing the returned measurement data. The upper computer software intuitively reflects the situation of the multi- taper surface of the tested mold to the user in the form of data table, data curve and 3D model diagram of the mold taper, and provides a true and reliable theoretical basis for the on-site operators to maintain the mold. The measurement principle: The mold multi-taper measuring instrument is a high-precision instrument. The whole instrument includes a high-precision laser ranging sensor, two digital servo motors, an encoder, a horizontal sliding screw, a vertical sliding screw, and a calibration console and controller etc. The equipment has many advantages such as high measurement accuracy, strong stability, easy installation and strong observability. The instrument is suitable for the multi-taper detection, surface flatness analysis and surface flaw detection of continuous casting molds in the continuous casting process of major iron and steel enterprises. It is suitable for round billets, square billets, slabs, etc., widely used and powerful. When measuring the multi- taper characteristics of the mold, the instrument is fixed on the top of the mold as shown in Figure 1. After the equipment is started, the self- inspection process is automatically completed, and the laser measuring sensor automatically returns to the initial zero position, and then the laser sensor scans along the inner surface of the mold under the drive of the digital servo motor, and then the laser sensor descends to a certain height to continue scanning for a circle. The entire inner surface of mold is repeatedly scanned from top to bottom. After the scanning is completed, the data is transmitted to the host computer through wireless communication or wired communication. The host computer software imports the collected data into the model base, and obtains the multi-taper status, surface flatness, cracks and other situation of the mold through calculation and analysis, which provide reliable maintenance reference data for on-site production and avoid production accidents on site due to the equipment failure. The features: Humanized human-computer interaction interface Convenient system settings Portable low power consumption design Compatible detection structure with lots of specifications High-speed and stable wireless data transmission High-precision laser scanning measurement One-click measurement design Own network wireless transmission Small and lightweight front-end measurement The parameters: Mold width range: 60~400mm Measurement accuracy: 0.01mm Spot diameter: 1.0x1.5mm (spot scan), 1.0x20mm (line scan) Measurement method: laser displacement measurement Measuring beam: 3200 points Movement mode: high precision servo Movement accuracy: 1mm/65536 pulses Single measurement time: less than 2min Power supply: DC12V Operating temperature: -20~80℃ Shock resistance: 50G (X, Y, Z axis)
