Automation core: Industrial PLC/HMI runs closed loop control of roll penetration, crown compensation, speed, and pass schedules; one touch recipe start triggers an auto threading sequence to minimize setup time and scrap. 
Work roll cassette: 7/9/11 precision ground, induction hardened alloy steel rolls with synchronized entry/exit pinch rolls ensure stable feeding and contact; optional chrome finish supports coated stock. 
Backup system: Multi row backup bearings beneath each work roll limit deflection to preserve flatness uniformity across the strip width, enhancing downstream quality. 
Drives: An electro mechanical main drive with helical gearbox and VFD maintains consistent surface speed, while servo actuators position penetration and left/right crown trim with high repeatability. 
Structure: A stress relieved welded frame with heavy side plates and tie bars reduces vibration and supports long term geometric accuracy under continuous duty. 
Sensors: Load/current monitoring with optional laser or roller flatness sensing at exit, entry edge guides, and loop control provide the inputs required for fully automatic pacing and adaptive correction.
