炉卷轧机张力对钢板下表面缺陷影响

Effect of Steckel Mill Tension on Lower Surface Defects of Steel Plate

钢板表面质量是板材的重要质量指标,本文详细分析炉卷轧机建张过程的原理及硬件组成,分析影响钢板下表面缺陷的关键因素。对钢板在卷轧道次的张力控制做了优化,并通过一段时间的生产验证了张力优化对钢板下表面缺陷的改善效果。

The surface quality of steel plate is an important quality index of steel plate.This paper analyzes the principle and hardware composition of steckel mill tension process in detail,and analyzes the key factors affecting the lower surface defects of steel plate.The tension control of steel plate in rolling passes is optimized,and the improvement effect of tension optimization on the lower surface defects of steel plate is verified through a period of production.
