Product Description

1. Characteristics of tungsten carbide:

High hardness and good wear resistance: Hardness at room temperature can reach HRA78-89, good red hardness under high temperature, 600ºC over high-speed steel, 1000ºC over the room temperature of carbon steel.
 
High mechanical strength: The compressive strength of up to 6000MN/, 900ºC,the bending strength can still above 6000MN/. 
 
High modulus of elasticity: Good rigidity at room temperature, no significant plastic deformation. Young's modulus is 2-3 times than steel.
 
Corrosion resistance and good oxidation resistance: acid, alkali, at 6 00-800ºC without significant oxidation.
 
The linear expansion coefficient is small: in the range of 20 to 400ºC for steel 0.35-0.65 . 
 
 Conductivity: similar with iron and ferroalloy.

The new generation of high-speed wire and rod composite roll is mainly used in the front frame of deformed steel bar and bar mill, which is using a new generation of high-speed wire rod and hot roll material can significantly reduce the change slot and roll changing times, also reduce labor intensity and improve labor productivity, improved surface quality and lumber rolled percentage, thereby obtaining a significant economic benefit.
