100% virgin material 150*15*95 YG15 tungsten carbide roller for rebar

The rolling force, rolling torque, and thermal conductivity properties of different stands are different, so different stands should use different brands of carbide rolls. In the design process of cemented carbide roll materials, it is necessary to ensure a reasonable match between the strength, hardness and impact toughness of the rolls. A database of thermophysical parameters of different alloy grades should be established, and computers should be used to optimize roll material design.

During the rolling process, the wear of cemented carbide rolls is not only affected by external conditions such as temperature, rolling pressure and thermal shock load, but also by internal factors such as the existence between the hard phase WC and the bonding phase Co/Co-Ni-Cr. It is affected by quite complex physical and chemical reactions. This makes the wear situation more complicated. Therefore, it is necessary to strengthen the research on the mechanism in this aspect.
