摘要
平整工序作为热轧全流程控制的最后一道工序,起着至关重要的作用。特别是在当前钢铁市场异常严峻的形势下,如何保证经平整工序的钢卷表面质量,保证进入到冷轧或是终端用户手中的热轧钢卷质量优良,显得尤为关键。本文通过对京唐公司2250热轧平整线生产过程中出现的主要质量缺陷种类及成因进行简要介绍,并有针对性的提出控制措施,杜绝了带钢在平整机组产生中产生的次生质量问题。
The Skin Pass process,as the last working procedure of the whole process control of hot rolling,plays an important role.Especially in the current iron and steel market is unusually grim situation,how to ensure the surface quality of the rolling process of the steel coil,to ensure the quality of hot rolled steel coils into the hands of the end users of the cold rolled or end users,appears particularly critica.The JingTang 2250 Hot rolled flat production line in the process of main quality defects causes and types are briefly introduced in this paper,And the control measures are put forward,the secondary quality problems of steel coils in the generation of flat rolling mills are avoided.
