【摘要】 讨论了不同退火工艺对 St1 2 冷轧薄板性能的影响。全速加热 ,6 80℃保温 2 0 h,能明显改善钢的性能 ,全氢罩式炉退火后钢板为等轴铁素体晶粒 ,并可观察到明显的饼形晶粒特征更多还原

【Abstract】 This paper discusses the effect of different annealing process on properties of St 12 cold-rolled steel sheet Full-speed heating to (680 ℃) and twenty hour holding can improve the properties After annealing in bell-type furnace under H 2, the structure of the sheet is characterized by equiaxed ferrite grains and cake-type grains can be observed clearly更多还原
