LDT-L200 Ladle Lining Laser Thickness Gauge

LDT-L200 Ladle Lining Laser Thickness Gauge


Overview

LDT-L200 is a new generation of ladle lining thickness gauge launched by our
company. The system equipment emits a pulsed laser beam to the lining
surface of the ladle, and receives the returned laser light to measure its
flight time. Then the system equipment calculates the distance between the
equipment and the target point according to the transmission speed of the
laser. During measurement, the user pushes the equipment to a certain
position on the platform in front of the ladle, and the equipment can start
to scan and measure the target area of the ladle after the equipment
performs rapid self-positioning.



The detection principle

The measurement speed of LDT-L200 can reach up to 2,000,000 points per
second, and each scan can obtain distance data of more than 1.5 million
points. The actual surface curve of the entire ladle lining can be obtained
by combining the measurement data of different positions.

During the measurement, the laser head of the equipment rotates at a certain
step angle to rapidly change the angle of the pulsed laser beam. Within 1
minute, the three-dimensional surface contour of the ladle lining can be
formed, and the thickness information of the furnace lining can be obtained
through coordinate conversion calculation. The measurement accuracy up to
±2mm.

In order to accurately calculate the thickness of the lining in the ladle,
the measuring head of the laser thickness gauge is installed on the ladle
repairing platform. By moving the swivel arm for hoisting, the laser
scanning head is moved to the intersection position during measurement, and
the relative position of the laser head to the ladle mouth will be
calculated during installation. Through mathematical modeling, a complete 3D
figure of the thickness of the entire ladle lining can be displayed after
laser scanning
