3RCM is so called reversing cold rolling mill and dedicated to producing high-grade electrical steel (ES). High ductile-to-brittle transition temperature of high silicon content ES is apt to suffer brittle fracture while being rolled at room temperature. Therefore, it’s necessary for coils to be processed with pre-heating treatment beforehand. 3RCM is equipped with a pre-heating furnacefor high-grade ES. However, longer pre-heating time and poor inside coil lap temperature uniformity become the bottleneck of production. With improvement remedies applied herein, it not only improves the longer pre-heating time and poor inside lap coil temperature uniformity issue, but also saves the energy of natural gas and electricity consumption. 3RCM is so called reversing cold rolling mill and dedicated to producing high-grade electrical steel (ES).
