What materials made the rollers ?

The roller is an important part of the rolling mill in the steel rolling mill. It uses the pressure generated by a pair or a group of rollers to roll steel. It mainly bears the effects of dynamic and static loads, wear and temperature changes during rolling.

There are many types of rolls. The commonly used roll types include cast steel rolls, cast iron rolls and cast iron rolls. In order to ensure the accuracy of rolling steel bars and the service life of the rolls, more and more steel plants choose carbide rolls (tungsten carbide rolls). 

Carbide rollers have high hardness and good wear resistance. The hardness value at 700°C is 4 times that of high-speed steel; that is to say, the service life is 4 times that of steel rollers, so it can reduce the trouble of replacing molds and ensure Bar size and rolling efficiency.
