6 High Rolling Mill Solution
JINYE positions the 6 High Cold Rolling Mill as the core equipment for steel strip rolling mill projects that require plate shape control, stable gauge control, cold rolling production reliability and high production efficiency.
Each project is reviewed against strip grade, entry thickness, target gauge, maximum strip width, coil weight, rolling speed, plant layout and power supply conditions before engineering release.
Key Engineering Focus
Plate Shape Control
Roll system, hydraulic screw-down and flatness strategy support stable strip shape during rolling.
Automatic Control System
AGC, AFC, HMI, PLC and edge position control coordinate the steel strip rolling mill line.
Stable Operation
Drive, tension, roll gap and control settings are configured for repeatable production stability.
High Production Efficiency
The system supports high-speed cold rolling production and efficient steel strip processing.
