Selection of Traditional Hot Rolling Mill Roll Material and Heat Treatment Process. Hot rolling rolls often work in a high-temperature environment of 700°C to 800°C. They are in contact with hot steel billets and need to withstand strong rolling force. Subject to thermal fatigue with large temperature changes.

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.

The roll making procedure is always to be under control. The ratio of roll costs to the tons of material rolled is decreasing because of (i) better mill technology, and (ii) better roll performance. It is not due to the lower cost of the rolls. Low priced rolls are ultimately counter-productive. Rolls and roll material properties
