Rolling mills contain at least one pair of rollers. Steelmaking companies use them to manipulate the physical properties of raw sheet metal, including steel sheet metal. By passing sheet metal through a rolling mill, its physical properties will change. While they've evolved over the years, rolling mills have been around for centuries.

The singlegroove steel passing capacity of the finished roll is only 50 ~ 400t / groove according to the rolling specifications and process conditions. This means that a bar production line with a single shift (8h) output of about 1000t has to replace the rolling groove 35 times per shift, resulting in a long cumulative time for roll changing ...

In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its recrystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.
