Tungsten Cemented Carbide Roll Ring

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

Advantage of composite roll

• 1.The quality of steel products can be promoted. The surface quality and tolerance of products can be thoroughly improved. The negative deviation can be controlled more precisely.
• 2.The change frequency of groove and roll can be reduced. The downtime can be shortened. The labor intensity can be reduced in rolling workshop, increasing productivity and output can create greater economic benefit at the same time
• 3.The rejection rate of products can be reduced
• 4.Greatly reducing the steel cost per ton is an effective way for enterprise to reduce cost and increase benefit

Note: We can supply them according to the drawings provide by customers.
