Features:
1. Single motor drives the helical gear reducer (hard tooth face) through gear box and coupling. PLC and touch screen are adopted for control system.
2. Compressing: by air-liquid booster pump and underneath type of oil cylinder;
3. Roll clearance adjusting: automatically adjusted by servo motor driving middle slide wedge.
4. Top roll and bottom roll are horizontally positioned. Square-shape casting stands. Special bearing for high precision mills and bearing clearance eliminating device.
5. Unwinder, rewinder, dust collecting for trimming process, damping device are designed for continuous rolling process. The roll self-unloader is easy operated for roll changing.
6. Options for continuous rolling process: S roll preheating device, thickness tester, jointing platform.
