摘要
介绍了从奥地利引进的全氢罩式退火炉的特点,结合唐钢冷轧厂的生产实际情况,分析了影响退火工艺的多种因素,对主要产品SPCC钢种的退火工艺制度进行了优化,退火周期缩短了4～6h,机组月产量提高12.1%,产品合格率由95.5%提高到98%以上。
It is introduced the features of full- hydrogen bell- type annealing furnace imported from Austria. Based on the practical production of cold rolling mill of Tang Steel, it is analyzed various factors to affect an- nealing process, optimized the annealing process system of SPCC steel. And the annealing circulation is shortened by 4 to 6 hours, month output of a set raised by 12.1%, qualified product ratio increase from 95.5 to 98 percent.
