Cold-Reduction Mill Components
Precision-engineered for metal sheet cold-reduction mills, our heavy-duty calendar rollers and backup rolls deliver extended campaign life and consistent strip quality. Each roll undergoes controlled heat treatment and ultrasonic inspection to ensure freedom from internal defects.
Why choose us
Induction-hardened work rolls deliver up to 40% longer runs between regrinds, cutting unplanned stops and boosting throughput.
Proven in tandem cold mills processing 0.15–2.0 mm sheet.Precision-ground roll profiles and tight concentricity reduce vibration, helping you hold gauge tolerances within ±0.005 mm across the coil.
Backup rolls with optimized neck geometry maintain gap stability.Heavy-duty calendar rollers with chrome or ceramic coating resist marking and corrosion, extending service intervals by 30% in continuous lines.
Dynamic balancing minimizes runout at operating speeds.Controlled heat treatment creates a 12–18 mm hardened shell while preserving core toughness, preventing spalling under high rolling loads.
Ultrasonic inspection confirms freedom from internal defects.Standardized diameters and face lengths fit existing mill stands without adapter modifications, slashing changeover time by 25%.
Available for 4-high and 6-high mill configurations.Multi-stage finishing yields micro-surface uniformity below 0.2 µm Ra, critical for exposed automotive and appliance panels.
Options for chrome plating or ceramic coating available.Each roll type is engineered for a specific load path and wear pattern. The table below shows how our metallurgy and heat-treatment choices translate into measurable production benefits.
Deep, uniform hardened layer (60–65 HRC) with a tough alloy-steel core. Precision-ground to ±0.005 mm on diameter and face. Suitable for single-stand and tandem cold-reduction mills processing carbon steel, stainless, and non-ferrous strip.
Extended campaign life — fewer intermediate roll changes per shift
Forged high-alloy steel with grain-flow orientation that follows the roll contour. Proprietary heat-treatment schedule yields a wear-resistant shell (55–60 HRC) and a ductile core. Ultrasonically inspected to ASTM A388 standards.
Tighter gauge tolerance across all stands — less scrap at coil ends
Specialized steel grades selected for thermal conductivity and marking resistance. Multi-stage finishing achieves Ra ≤ 0.2 µm surface finish. Dynamically balanced for operating speeds up to 1200 m/min. Chrome-plating or ceramic-coating options available.
Consistent surface quality on coated and foil products — fewer rejects
On-site dimensional inspection and re-grinding to original OEM tolerances. Includes ultrasonic and magnetic-particle crack detection. Turnaround typically 5–7 working days for standard sizes.
Restored roll geometry at 40–60 % of new-roll cost
Induction-hardened work rolls, backup rolls, and calendar rollers built for cold-reduction mills that demand consistent surface integrity and extended campaign life.
Our induction-hardening process delivers a uniform hardened layer 8–12 mm deep while preserving core toughness. This reduces spalling risk under high rolling loads and extends time between regrinds compared to flame-hardened alternatives.
Backup rolls are forged from high-alloy steel to align grain structure with load paths. The result is a roll that resists fatigue cracking in multi-stand tandem configurations, maintaining gap geometry across long production runs.
Calendar rollers undergo multi-stage finishing to achieve surface roughness below 0.2 µm Ra. This consistency prevents marking on foil and film lines, reducing rejection rates and extending roller service intervals.
Every work roll, backup roll, and calendar roller is ultrasonically tested for internal defects before dispatch. This documented quality check gives mill engineers confidence in structural integrity before installation.
Roll necks are ground to bearing-seat tolerances within 0.01 mm. This minimises runout at operating speeds, reduces bearing wear, and helps mills achieve tighter gauge tolerances without additional pass schedule adjustments.
