[0002] The rolling mill, consisting of a frame, roll train, roll box, screw-down device, and drive unit, features a rectangular, integral frame arch cast from high-quality steel. The roll box consists of upper and lower split roll boxes that slide in tandem with the arch window. A rectangular saddle with backing bearings is housed within the roll box, connected to the roll box by a locking device. The lower roll box features a double wedge adjustment mechanism consisting of a swing cylinder, swing arm, connecting rod, and wedge. Crowning control devices, consisting of a hydraulic cylinder, rack, and gear, are located between the upper support rolls A and B, and between C and D. The mill provides excellent strip shape control, achieving a strip thickness accuracy of 0.001mm. The rectangular saddle and arch are easy to machine and precisely mate with, and the lower roll box is easily adjustable, maintaining a standard rolling line height.
