Definition of composite roll
Cemented carbide roll ring is a kind of tool material which consists of tungsten carbide and cobalt with high hardness and wear resistance.
The composite roll is that cemented carbide roll rings and steel shaft are compounded into a whole through the special method, which is used for rolling round steel, screw steel, square steel,, flat steel and angle steel,etc.
Suitable rolling speed of composite roll
2-50m/s
