Description

Technical Field

[0001] The utility model relates to the technical field of slab continuous casting and cutting, in particular to a numerically controlled double-flame continuous casting width-adjustable hot slab cutting machine. 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] The temperature of the steel billet is generally between 20-650℃. Under this condition, the measurement and alignment of the hot steel billet becomes a problem that needs to be solved. The specific problems are as follows: 1. The operator is in danger of burns when measuring close to the steel billet under high temperature baking; 2. The length of the ruler changes due to thermal expansion, resulting in inaccurate measurement data; 3. It is difficult to position and align the steel billet when it is placed at an angle.
