Tungsten Carbide Roller
- Used on the stretch-reducing mill for bars, thread steel bars and common wire with the durability 10 to 20 times higher compared to common steel roller. Applied for reinforcement wire cold rolling and forming.
- Reducing effectively the production cost and improving the quality.
- The material of roll blanks is sintered in the HIP furnace, 100% virgin material.
Why Choose Tungsten Carbide Roller
Tungsten carbide roller has superior performance, stable quality, high precision, good wear resistance and high impact resistance. Carbide roller has high hardness, which is not affected by environmental or external temperature change, therefore it can be used in an extremely hot or cold environment.
1. Excellent surface mirror finish.
2. High hardness, round HRA 87 or even to HRA91.
3. High wear resistance and corrosion resistance.
4. The service life of tungsten carbide is 50 times longer than common steel tools.
