Gauge stability
High-precision control helps reduce off-gauge strip and downstream rework.
Cold Rolling Mill
High-precision mills for demanding strip reduction.
JINYE cold rolling mills are configured for multi-grade production, accurate thickness control and energy-conscious operation in stainless steel, silicon steel and carbon steel plants.
Overview
From 20-high precision rolling to practical 4-high production.
The rolling mill is specified around material strength, entry and exit gauge, coil weight, target speed, flatness requirement and automation level. JINYE supports AGC and AFC integration for more stable production.
- Self-developed 20-high cold rolling mill capability for 201 stainless steel and multi-grade production.
- Strip width coverage from 350 mm to 1780 mm across multiple mill types.
- Typical energy reduction around 30% when the complete drive, control and process route are optimized.

| Offset 8-high mill | 350-1780 mm | 500-800 m/min | Balanced stiffness, efficiency and process flexibility |
| 6-high cold rolling mill | 550-1780 mm | 600-1500 m/min | High-speed rolling and wider strip production |
| 4-high cold rolling mill | 350-1450 mm | 200-500 m/min | Conventional rolling and cost-focused production |
Production Value
Stable gauge, flexible grades and lower operating cost.
Mill performance is created by the mechanical stand, drive system, roll technology, tension control and automation working together.
Grade flexibility
Multiple mill configurations support stainless steel, silicon steel and carbon steel routes.
Energy focus
Drive, lubrication, control and schedule optimization reduce total power demand.
Custom layout
Equipment arrangement, automation and utility interfaces are matched to the plant.
