Iron rolls are the backbone of modern metal forming, essential for plate mills, wire rod mills, and section mills. Beyond merely providing pressure, high-quality iron rolls must maintain surface integrity under extreme thermal stress.
At CYKC Group, we engineer our iron rolls to bridge the gap between cost-efficiency and heavy-duty performance, ensuring your production line experiences less downtime and superior strip quality.
Our Core Series: Alloy Iron Rolls Overview
The CYKC Series features a range of specialized cast iron rolls, including Indefinite chilled cast iron roll (ICCI) and Pearlitic ductile cast iron rolls (SGP). These are specifically designed for finishing stands where surface finish is non-negotiable.
Key Advantages:
- Superior Hardness Gradient: Optimized microstructure ensures consistent hardness throughout the working layer.
- Enhanced Thermal Fatigue Resistance: Specifically treated to prevent surface spalling and “fire-cracking” during high-speed rolling.
- Reduced Friction Coefficient: Minimizes power consumption and prevents material sticking.

Industrial Applications
CYKC Group’s iron rolls are field-proven in the following environments:
Wire Rod Mills: Finishing blocks for high-speed delivery.
Plate & Strip Mills: Work rolls for roughing and finishing stands.
Section Mills: Universal stands for H-beams and structural steel.
Why Partner with CYKC Group?
We don’t just manufacture rolls; we provide rolling solutions. By utilizing vertical and horizontal centrifugal casting technology, we ensure a dense microstructure free of internal defects. Every roll undergoes rigorous Ultrasonic Testing (UT) and Hardness Verification before shipment.
With a track record of supporting over 50 mills globally, our technical team can help you select the exact grade to optimize your “tons per roll” ratio.
