Automatic Hydraulic Reversing Cold Mill AGC Reversible Cold Rolling Mill Machines

Automatic Hydraulic AGC Reversible Cold Rolling Mill Machines

Hydraulic AGC rolling mill is popular and advanced in high precision high speed cold rolling metallurgical industry 

Hydraulic press down or up system cold rolling mill Advantages:

1. Small inertia, fast reaction and high sensitivity guarantee high precision rolling, thickness deviation can be controlled within 1% and increase the percentage of quality strip.
2. hydraulic system fast and precise response can effectively remove the interference of frequently periodic change of roll gap caused by roll eccentricity
3. Collect , Record and Display Rolling Process parameters including faults. Good HMI Dialogue.
4. Rolling speed can be very high, like 240m/min, 480m/min, 600m/min.
5. Hydraulic AGC high precision is especially obvious on medium and large width rolling mill.

Characters:

1. Hydraulic AGC press-up system with automatic control, including hydraulic press-up cylinders, AGC control system, hydraulic station, thickness gauges, with functions of constant roller clearance position control, constant pressure control and automatic tilt adjusting control.
2.  CPU computer automatic control system
3. HIM touch screen for dynamic display, rolling parameters setting, breakdown alarms and report printing.
4. Digital DC or frequency AC drive
5. Drive middle rollers (separately drive upper middle roller and lower middle roller.
6. rollers cooling control divided in five zones , emusified water flow control
7. work roller positive/negative bending control
8. Presetting of middle roller transfer and middle roller positive bending control
9. zero setting of rolling centerline by wedge.
10. work rollers and middle rollers fast changing equipment
11. automatic adjustment of rolling speed and tension
12. Protection measures in case of strip break, accidents alarms and emergency stop.
13. oil gas lubrication for work rollers, middle rollers and backup rollers.
14. Roller bearings for backup rollers
15. X-ray thickness gauge
16. Rolling process linkage and defect alarms controlled by PLC
17. The presetting of rolling process, the inspection, display and alarm of rolling process parameters and critical machine parameters
