What is the cold rolling coil line (cold rolled coil mill)?

The cold rolled coil line refers the cold rolled steel coils production lines and mills, the rolling process for such coils are under the steel recrystallization temperature, so it calls cold rolling process. It is professional equipments to produce the cold rolled steel coil and steel sheet.

Mostly, the cold rolling temperature is at room temperature, but the cold rolled steel coils is also at a high temperature after the rolling because of the pressing process. The raw material of the cold rolled coil are from hot rolled steel coil mills, the cold rolled coil production line press the thicker hot rolled coils to thin coils by extrusion.Befor the pressing and extrusion process, the raw material hot rolled coils need to do the pickling first, and after the rolling, the coils need to do the heat treatments(mainly annealed) and leveling process. They are all necessary in a cold rolled steel coils production line.

In a cold rolled coils plant, the finished coils could be recoiling coiles, steel sheet or strips. For different purpose, there are different equipments in the line. The engineering and design work should be done accordingly. Tianjin Tianzhongzhongzhi will persist in the business ethic of technology as guide, product as core, quality as guarantee, service as foundation. With innovative design concept,sincere enthusiastic attitude, enterprising spirit, honest reputation, spirit of team cooperation , we keep up with the latest frontier of metallurgical technology and provide customers with the best products and services.
