OverviewrnrnLDT-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 transmission 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 the certain measuring point 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.rnrn rnrnThe measuring principlernrnThe 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.rnrnDuring 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.rnrnIn 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 scanningrnrn rnrnThe main componentsrnrn1. Laser measuring headrnrn2.
