Cold Rolling Mill. Cold Rolling Mill. Unlike hot rolling, Cold rolling mill involves the passing of steel and other metal materials sheet between more than one rotating roll at a temperature below the recrystallization temperature. In this case, the rotating rolls are not heated at all, thereby making the metal harder and more long-lasting.
