Skin Pass Mill
The Features And Specs
The perfect automatic control : including automatic constant rolling force control (AFC), automatic constant elongation control(AEC), automatic position control(APC) and automatic constant tension control(ATC).
The higher automation level: Roll gap quick automatic open and recover when welding seam passing, automatic calibration online, quick change roll online and hydraulic locking.
The latest soft rolling mode developed by YWLX: The soft rolling mode has carried out not to open rolls, when welded seam passing. If rolling force is less than 2000KN, the welded seam can pass directly. If rolling force is more than 2000KN, it will decrease up to 2000KN and welded seam will pass directly without opening rolls. Soft rolling mode will ensure not to damage roll surface.
The higher electrical control system: Driving control system will use full digital inverter speed control and Siemens’ or ABB’s speed control device. Basic automation will use Siemens’ or ABB’s PLC control with touch screen. Bending roll system will use servo control.
The perfect HMI: The mill will use HMI to collect, display and store the data.
Flatness control: The mill will use positive/negative bending system of work roll to control flatness.
Automatic elongation control: By rolling force control to carry out elongation control.
Process of the mill: skin passing by wet/dry as the process requirement.
Equipped with high pressure water system and anti-crimping roll and anti-cross breaker roll.
Auxiliary system of the mill: including medium pressure hydraulic station and high pressure servo station.
