What Are Cemented Carbide Rolls?
Cemented carbide rolls are precision tools made from cemented carbide, combining tungsten carbide particles with a cobalt binder through vacuum sintering for exceptional hardness and wear resistance in wire rolling applications. Rettek's manufacturing integrates this process to produce parts with uniform grain size, ideal for high-speed, high-impact environments like VSI crushers and adaptable to rolling mills.
Why Do Wire Rolling Mills Need Carbide Rolls?
Wire rolling mills need carbide rolls to combat rapid wear from abrasion, impact, and thermal stress that degrade steel rolls, causing frequent replacements and downtime. Cemented carbide's wear resistance, corrosion resistance, and high strength, as seen in Rettek's rotor tips and studs, provide longer service life and cost savings in demanding metal forming operations.
| Property | Steel Rolls | Cemented Carbide Rolls (Rettek Style) |
|---|---|---|
| Wear Life | 1x baseline | 3–5x longer via welded construction |
| Key Properties | Moderate hardness | Wear, impact, corrosion resistance |
| Environment Suitability | Standard | High-impact, high-heat |
| Downtime Impact | High | Reduced by preventing breakage |
How Are Precision Cemented Carbide Rolls Manufactured?
Precision cemented carbide rolls are manufactured through Rettek's full in-house chain: raw material preparation, batching, pressing, vacuum sintering, tool design, production, and automated welding. This ensures consistent quality, with proprietary temperature control for uniform grain size, mirroring processes used for HPGR studs and VSI components.
