As the steel industry evolves, the demand for efficient and durable rolling solutions has never been greater. Tungsten carbide roll rings, known for their superior performance, have become essential in high-speed wire rod mills and cold-rolling ribbed steel bar mills. Combining advanced materials with cutting-edge engineering, these roll rings are reshaping modern steel production.
Applications of Tungsten Carbide Roll Rings
Tungsten carbide roll rings excel due to their exceptional thermal conductivity, heat resistance, and wear resistance. These properties allow them to maintain hardness under high-temperature conditions and withstand heavy impact loads. Initially developed for high-speed wire rod rolling, these roll rings now play a crucial role in manufacturing wire rods, bars, and deformed steel bars.
In finishing mills, requirements vary by stand position:
- Front stands: Handle heavy loads and strong impacts, requiring high hardness and thermal fatigue resistance.
- Rear stands: Encounter lighter loads, making wear resistance and thermal fatigue resistance the primary concerns.
This tailored approach ensures superior performance across the rolling process.
Material Properties: Strength Meets Toughness
Our tungsten carbide roll rings are crafted from two advanced material systems:
- Wc-Co
- Wc-Co-Ni-Cr
These materials balance the hardness and wear resistance of tungsten carbide (WC) with the toughness and strength of binders (Co-Ni-Cr). Key metrics include:
- Bending strength: Up to 2800 N/mm²
- Impact toughness: 4-6×10⁶ J/m²
These properties make our roll rings ideal for high-stress environments and demanding steel production processes.
Advanced Manufacturing Processes
Our tungsten carbide roll rings are produced using state-of-the-art manufacturing technologies, including:
- World-class paraffin and spray-drying granulation for consistent grain quality.
- 500-ton alpha press, imported from the USA, ensuring high compaction density.
- Hot isostatic pressing (HIP) to enhance internal structure and eliminate voids.
- Low-voltage sintering furnace for improved material microstructure.
- Precision grinding and finishing equipment from Germany for exceptional dimensional accuracy.
These processes ensure that every roll ring delivers unmatched durability and performance.
