摘要
根据攀钢热轧板厂工艺设备现状,以Q235钢为研究对象,通过理论分析和现场试验,摸索出了超细晶粒钢的热轧工艺,使晶粒细化至4～5μm,σs、σb均提高100MPa左右,提高了产品的综合性能,实现了在攀钢1450mm普通热轧机上生产超细晶粒钢的技术创新。
According to the conditions of process and equipment in Hot Strip Mill of PZH steel,the reseaonable process for ultra-fine grained steel of Q235 has been established.It is a technological innovation of using 1450mm conventional hot mill to produce ultra-fine grained steel in PZH steel.
