Cemented Carbide Composite Roll

Cemented Carbide Composite Rolls

Longer Roll Life. Lower Rolling Cost. Higher Rolling Efficiency.

Replace conventional alloy steel rolls with precision-ground cemented carbide roll rings to significantly improve rolling quality, reduce roll changes, minimize mill downtime, and increase productivity for bar mills, wire rod mills, and section mills.

Typical Applications

Rebar rolling mills

Intermediate Stands.
Pre-finishing Stands.
Finishing Stands.
Bar Mills.
Wire Rod Mills.
High-Speed Wire Mills.

Why Choose  Composite Rolls Instead of Alloy Steel Rolls?

Compared with traditional alloy steel and cast iron rolls, Cemented Carbide Composite Rolls provide exceptional wear resistance, superior thermal stability, and excellent groove retention throughout the rolling campaign. Their composite design combines precision-ground tungsten carbide roll rings with a reusable alloy steel shaft, ensuring consistent rolling accuracy and extended service life.

Advantages of Cemented Carbide Composite Rolls

Instead of conventional alloy steel rolls, CYKC Cemented Carbide Composite Rolls help rolling mills:

Improve rolling quality.
Maintain stable groove accuracy.
Reduce roll consumption.
Increase mill productivity.
Extend rolling campaigns.
Reduce maintenance downtime.
Lower production cost per ton.

Engineered with premium tungsten carbide roll rings, CYKC Group Composite Rolls improve rolling quality, reduce roll changes, minimize mill downtime, and maximize productivity in modern bar and wire rod mills.

Technical Specifications

Cemented carbide is mainly made of tungsten carbide particles and metal binder (often cobalt),When needed, nickel, chromium, etc., is added in order to improve its hot cracking resistance and corrosion resistance. Different binder content and corresponding WC particle size can yield different cemented carbide grades. CYKC Group has a series of cemented carbide roll rings grades to apply different rolling mills and stands.

The relationship between the physical and mechanical properties of cemented carbide grades and the content of metal binders:

Applications

FAQ

Which rolling mills are suitable?

• Traditional Bar Mills.
• Wire Rod Mills.
• High-Speed Wire Mills.
• Rebar Rolling Mills.
• Small Section Mills.

Can the roll rings be replaced separately?

Yes. One of the key advantages of Cemented Carbide Composite Rolls is that the carbide roll rings can be replaced independently when worn. The steel shaft and other components can continue to be used, significantly reducing replacement costs, maintenance time, and overall operating expenses.

Do you provide OEM service?

Yes. CYKC Group provides comprehensive OEM and custom manufacturing services. We can manufacture Cemented Carbide Composite Rolls according to customer drawings, technical specifications, groove designs, roll dimensions, and rolling mill requirements. Our engineering team also provides technical support for product selection and application.

Every Cemented Carbide Composite Roll undergoes strict quality inspection before shipment. Available inspection reports may include:

• Chemical Composition Analysis.
• Hardness Test Report.
• Density Test Report.
• Dimensional Inspection Report.
• Surface Quality Inspection.
• Mechanical Properties Report (when required).
• Material Certificate.
• Final Inspection Report.
