Continuous casting slab laser sizing system

Abstract

The invention discloses a continuous casting billet laser sizing system. The continuous casting billet laser sizing system comprises a PLC unit, a laser detection unit, a display unit and a calculation unit, wherein the PLC unit controls a roller bed of a continuous casting machine and a flame cutting machine; the laser detection unit is connected with the PLC unit and is used for detecting relative positions of continuous casting billets; the display unit is connected with the PLC unit and is used for monitoring operating conditions of the whole system and allowing workers to input necessary data during debugging; the calculation unit is connected with the PLC unit and is used for converting the relative positions, detected by the laser detection unit, of end surfaces of the continuous casting billets into actual lengths of the continuous casting billets. The continuous casting billet laser sizing system has the advantages of being high in sizing precision, stable and simple in calibration, easy to install, debug, operate and maintain, low in operation cost and accurate in cutting, improves sizing rate and yield and reduces rejection rate.

Description

technical field [0001] The invention relates to the field of continuous casting machinery and equipment, in particular to a continuous casting slab laser sizing system. Background technique [0002] In the production process of continuous casting machines in metallurgical enterprises, the precision of continuous casting slab sizing directly affects the output, product quality and cost of continuous casting machines. With the change of the market and the improvement of the quality requirements of continuous casting slabs, the pressure of cost is increasing, the specifications of cut-to-length are more and more, and the requirements for the accuracy of cut-to-length are getting higher and higher, especially for full-length production and continuous casting The implementation of billet hot-feeding process puts forward stricter requirements for continuous casting billet cut-to-length. [0003] At present, there are mainly three cut-to-length methods for continuous casting machi...
