High Precision Hydraulic AGC Cold Rolling Mill Machine Reversible or Tandem

Hydraulic AGC rolling mill is becoming more and more popular in metal strip rolling industry for its high precision, high speed and high automation

Screw down of Rolling Mill has options of mechanic type and hydraulic AGC type,

• mechanic type is composed of motor,speed reducer,brake,worm screw, spherical pad,etc. upper roll can be adjusted quickly and frequently with large stroke and without rolling load, simpler structure and easier maintenance, complex transmission system and lower sensitivity, not suitable for high speed high precision rolling.
• Hydraulic screwdown is composed of hydraulic cylinder, servo valves, hydraulic system, as well as checking meters and computing control system, which don't have complex transmission structure.

Hydraulic press down or up system cold 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
