1.0. Summary

概述

500MM four roller irreversible cold rolling mill is used to roll hot rolled coils,which are ordinary

carbon steel as material and 2mm as thickness, into cold rolled coils which are 1.5mm thick and

have required surface hardness

500MM 四辊不可逆轧机组是在常温状态下，将材质为普通碳钢，厚为2MM热轧带卷，轧制成

厚为1.5MM 并具有所需光洁度的冷轧带卷
