Cold Rolling/Process Line

Overview

The cold rolling mill is used to pass hot-rolled coils produced from the hot rolling mill between two rotating rolls and produce products of the desired thickness. The cold rolling process provides a more refined surface, improved mechanical properties and excellent thickness product precision. Cold rolling mills are largely divided into the TCM (Tandem Cold Rolling Mill) and the RCM (Reversing Cold Rolling Mill). In the TCM, material passes 5 or 6 rolling mills continuously to obtain the desired thickness, while in the RCM, material passes a single rolling mill multiple times.

We have established the foundation for independent implementation of cold rolling mill projects through continuous technology development and commercialization processes. Recognized for our technological excellence, we are penetrating the global market, as shown through winning the contract for the CSS and CRM project in Brazil.
