Flat Tungsten Carbide Roll Rings Ribbed Surface , Tungsten
Carbide Parts For High Speed Wires
Product Description& application:
Tungsten Carbide roll rings 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 roll rings, 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.
Recommended Grade: LZ30/LZ40
Grade Recommended: LZ30/LZ40
LZ30 Used for rolling cold rolled ribbed steel bar.
LZ 40 Used for rolling cold rolled ribbed steel bar with strong strength.
