A control device for dynamic soft reduction of slab continuous casting

Abstract

The invention discloses a control device for dynamic soft reduction of slab continuous casting, which can make the lower block or buffer lower pressure seat have a certain vertical buffer effect through the setting of a strong buffer spring, so that , the rear end of the dynamic roll seat can have a certain buffering effect, so that when the continuous casting workpiece moves from the rear pressure roller to the direction of the front pressure roller, the continuous casting workpiece can be pressed down step by step. The elastic down-pressing of the pressure roller facilitates the rigid down-pressing action of the subsequent front-pressing roller, realizes the dynamic down-pressing control, ensures the performance of the continuous casting slab, and prevents the internal defects of the slab and excessive strain and concentration during the straightening process. problems, reduce the internal cracks of the continuous casting billet, and at the same time provide certain favorable conditions for increasing the casting speed of the continuous casting billet. Real-time monitoring of working conditions.

Description

technical field [0001] Specifically, the invention relates to a control device for dynamic soft reduction of slab continuous casting, and relates to the relevant field of auxiliary equipment for continuous casting machines. Background technique [0002] For continuous casting of slabs, due to dynamic soft reduction, the continuous caster can control the final solidification stage, avoid loose center of slab and minimize segregation. Dynamic soft reduction produces slabs with the best intrinsic quality. As the principle of direct strip rolling from thin slabs has been successfully practiced around the world, iron and steel enterprises producing high-quality products have generally adopted soft reduction control technology. However, during the production of the slab under dynamic soft reduction, since the slab will be subjected to tension and pressure during the production process, when the pressure is not stable or the pressure changes rapidly, large cracks are likely to occ...

AI Technical Summary

Problems solved by technology

However, during the production of the slab under dynamic soft reduction, since the slab will be subjected to tension and pressure during the production process, when the pressure is not stable or the pressure changes rapidly, large cracks are likely to occur inside the slab. Problems such as cracks and large stress concentration affect the quality of the slab, thereby affecting the manufacturing rate of the slab, resulting in reduced precision and low efficiency
