THE HYDRAULIC SYSTEM FOR ALUMINIUM FOIL ROLLING MILL
Hydraulic system including: press-up system, bending roll balance, auxiliary, and centering systems.
- The system pump station adopts the integrated installation form of the oil tank and the pump, and the structure is compact; the system is equipped with a backup pump, and when one fails, the other is started, providing a reliable guarantee for continuous production.
- The system adopts self-enclosed filter cooling method, which has high cleanliness, which is beneficial to improve the adaptable life of hydraulic components; the filter element is simple and convenient to replace, which is beneficial to reduce the oil temperature of the oil.
- The pump station is equipped with liquid level alarm display, liquid temperature alarm display, pressure alarm display and other functions to provide more effective guarantee for the normal operation of the equipment.
- The improvement of the system technology effectively reduces the leakage rate of the pump and valve installation surface and ensures a good working environment.
- The valve station adopts the frame structure of the integrated block, which is compact and simple and convenient for maintenance.
Press-up system and roll control system
- Press-up system
The press-up system provides energy to the press-up cylinder of the rolling mill, and performs servo control on it according to the pressure, tension, strip thickness and position feedback signals to ensure product thickness accuracy. The system adopts advanced electro-hydraulic servo control technology to make the rigidity of the rolling mill adjustable. Under the control of the AGC system, it effectively realizes the thickness accuracy and shape accuracy requirements of the rolled strip.
