Cemented Carbide Roll Rings
Overview
Cemented Carbide Roll Rings, also known as Tungsten Carbide Roll Rings, deliver exceptional performance in high-speed wire rod, bar, and rebar rolling mills. Combining superior thermal conductivity, high hardness retention at elevated temperatures, excellent wear resistance, and remarkable fatigue strength, these roll rings outperform traditional materials in demanding production environments.
SC-ROLLS™️manufactures high-quality Cemented Carbide Roll Rings in two material series: WC-Co and WC-Co-Ni-Cr, offering optimal mechanical properties to meet diverse rolling applications.
Features
- High Hardness & Wear Resistance: The tungsten carbide (WC) phase provides outstanding hardness and wear resistance, ensuring long service life under continuous operation.
- Excellent Strength & Toughness: The metallic binder system (Co, Ni, Cr) delivers superior impact toughness and bending strength, with bending strength up to 2200 MPa and impact toughness of (4–6)×10⁶ J/㎡.
- Thermal Stability: Maintains hardness and strength under high temperatures, reducing wear and thermal fatigue during high-speed rolling.
- Optimized Composition: WC-Co offers balanced hardness and toughness, while WC-Co-Ni-Cr enhances thermal fatigue resistance and overall durability.
Applications in Rolling Mills
Cemented Carbide Roll Rings are designed for both front and rear stands in modern finishing and precision rolling mills:
- Front Stands: Handle larger cross-sections and higher loads. Roll rings here require high strength and excellent thermal fatigue resistance, with wear resistance as a secondary priority.
- Rear Stands: Operate under lower loads and impacts. Roll rings for these stands prioritize wear resistance and thermal fatigue protection, ensuring consistent surface quality of rolled products.
Typical applications include:
- High-speed wire rod mills
- Bar mills
- Rebar rolling
- Precision finishing lines
