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.

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.

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.

Overview: In the steelmaking production process, the ladle is the key equipment for holding molten steel, secondary refining, and continuous pouring. In a modern steelmaking plant, refractory materials are required for converters, refining, and ladles. In the steelmaking process, ladle is the most important part in the use and consumption of refractory materials. Improving the service life of ladles and reducing refractory consumption is the key technology for steelmaking plants to save costs and reduce energy consumption for green production. In order to ensure the orderly operation of the ladle, save the consumption of refractory materials, prolong the service life of the ladle, and ensure the safe operation of the ladle, Wuhan CenterRise M&C Engineering CO. developed and launched the LDT-N200 integrated management system for the ladle. Introduction: LDT-N200 ladle integrated management system integrates LDT-L200 ladle lining thickness gauge, TBP-S300 ladle, tundish baking temperature and leakage monitoring system, RFD -C100 metallurgical electronic positioning system, and also integrates SQL Server database and NeuralWare (American computer software company) neural network software NeuralWorks to realize intelligent and optimized management of ladles. LDT-L200 ladle lining thickness gauge uses a laser area array scanning sensor to accurately measure the real-time thickness of the ladle lining, calculate the lining loss, and predict the service life of the ladle. TBP-S300 ladle, tundish baking temperature and leakage monitoring system uses infrared thermal imaging camera and embedded armor wire system to comprehensively monitor and prevent ladle leakage. RFD-C100 metallurgical electronic positioning system installs RFID electronic tags on all ladles to realize full-time and full-space ladle positioning and tracking. LDT-S200 ladle optimization control and analysis software, based on SQL Server database, B/S network structure, realizes online management of ladles, and adopts BP neural network system to realize intelligent optimization control of ladles. LDT-N200 ladle integrated management system can realize ladle age management based on ladle lining data and neural network algorithm, safety process control of ladle turnover and use, full-time tracking management of steelmaking production and full-space tracking management of ladle use and provide optimal control and management of steelmaking production and ladle maintenance. Comprehensive ladle measurement and monitoring, ladle positioning and management, and data management and optimization enable the LDT-N200 ladle integrated management system to fully realize ladle entire process management, optimize the service life of ladles, and comprehensively reduce the cost of refractory materials.
