Product Overview
The Cold Rolling Mill range covers 20-high Sendzimir, 18-high, offset 8-high, 6-high and 4-high systems. Selection is based on material strength, incoming thickness, target thickness, strip width, line speed and required strip shape.
JINYE developed a domestic 20-high mill solution capable of rolling 201 stainless steel, helping customers expand material compatibility and production range. Energy-saving drive systems and AGC/AFC-ready automation can be included when the process requires higher precision and repeatability.
Specification Range
- 20-high, 18-high and offset 8-high mills: width options from 350 mm to 1780 mm, with reference speeds from 500 to 800 m/min.
- 6-high mills: width options from 550 mm to 1780 mm, with reference speeds from 600 to 1500 m/min.
- 4-high mills: width options from 350 mm to 1450 mm, with reference speeds from 200 to 500 m/min.
- Power consumption can be reduced by approximately 30% compared with conventional configurations, depending on process and drive design.
| Mill configuration | Typical strip width | Reference speed | Application focus |
|---|---|---|---|
| 20-high Sendzimir | 350-1780 mm | 500-800 m/min | High precision rolling for stainless steel, silicon steel and carbon steel strip. |
| 18-high | 350-1780 mm | 500-800 m/min | Flexible reduction, stable thickness control and strip-shape performance. |
| Offset 8-high | 350-1780 mm | 500-800 m/min | Compact roll arrangement, reduction flexibility and project-specific strip-shape control. |
| 6-high | 550-1780 mm | 600-1500 m/min | Higher-speed rolling where process route and material strength allow. |
| 4-high | 350-1450 mm | 200-500 m/min | General cold rolling and project-specific upgrade applications. |
Final rolling force, motor power, roll system, coil weight and automation scope are confirmed after material and production target review.
Typical Applications
- Cold reduction of stainless steel, silicon steel and carbon steel strip.
- Production lines requiring stable thickness control, surface quality and strip flatness.
- Lines combined with Strip Cleaning Line, Steel Coil Slitting Line and Tension Leveler equipment.
