Description

 

Ribbed Wear Resistant Tungsten Carbide Roller , Tungsten

 

Carbide Parts Enhance Strength
 

Product Description& application:

Tungsten Carbide Roller as the characters of high wear resistance, high corrosion resistance and good compressive properties which is an important parts in the steel bar and wire rod rolling. The rolls are primarily applied in high speed wire line, Kocks three roll mill, seamless pipe stretch reducing mill, three dimensional rolls for cold-rolled ribbed steel bar, and composite roll for hot-rolled bar screw thread steel etc

 

ZHUZHOU LIZHOU carbide roller, which ribbed accuracy and mark clear, at same time to improve the performance of steel, enhance the strength. It makes sure that the quantity of a rolling reach to 800-1500 tons. Carbide roller can be repaired repeatedly, and greatly reduces the production cost, significantly improves the efficiency.


Production Process:

Below are the production processes of tungsten carbide roller, to ensure high quality, we assureed our customers that:
1. All materials are tested in terms of density, hardness and T.R.S before use.
2. Every piece of product goes through in-process and final inspection.
3. Every batch of product can be traced.
