CSP生产SPHC板材的冷轧退火工艺优化

Optimization of Cold Rolling and Annealing Processing for Hot Rolling Strip(CQ/SPHC) of CSP

摘要: 对酒钢CSP生产的SPHC热轧钢进行了冷轧退火及相关试验。研究表明,当冷轧压下量为70%,退火温度为700℃时,可以得到良好的织构和优异的冲压性能。

Abstract: Cold rolling and annealing tests for hot rolling strip steel of JISCO CSP were performed and the results show that the hot rolling strip(CQ/SPHC) of CSP exhibits favorable texture and optimal drawing properties at the cold-rolling reduction rate of 70% and annealing tempreture of 700℃.
