Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting slab production, in particular to a continuous casting slab longitudinal cutting laser alignment and verification device. Background Art

[0002] Continuous casting is an advanced casting method. Its principle is to pour molten metal into a special metal mold called a crystallizer, and the solidified (crusted) casting is continuously pulled out from the other end of the crystallizer. It can obtain castings of any length or specific length. With the continuous increase in the output of continuous casting production and the acceleration of the pace, customers have higher and higher requirements for the quality of billets. Due to the amount of customer orders, the phenomenon of online adjustment of billet width often occurs during the production of continuous casting billets, which results in billets with inconsistent widths at both ends. It is called "width-adjusted billet". In order to improve the utilization rate of molten steel and reduce the comprehensive cost of steelmaking, each steel mill cuts the two sides of the width-adjusted billet longitudinally into qualified billets with regular shapes for sale.

[0003] Before cutting, the cutting position needs to be determined on the billet, and the temperature of the billet is generally 20-650°C. Under this condition, the measurement and alignment of the hot billet will face the following problems: 1. The operator is in danger of burns when measuring close to it under high-temperature baking; 2. The length of the ruler changes due to thermal expansion, resulting in inaccurate measurement data; Therefore, providing a laser alignment and verification device for longitudinal cutting of continuous casting slabs is a technical problem that technical personnel in this field urgently need to solve.
