Description

Technical Field

[0001] The invention relates to the technical field of rolling mills, in particular to a steel processing rolling mill. Background Art

[0002] The rolling mill includes a frame, a roll system, a roll box, a pressing device, and a driving device. Its characteristics are that the frame is a rectangular integral frame arch cast by high-quality steel, the roll box is an upper and lower split roll box that slides with the arch window, and a backing bearing rectangular saddle is installed in the roll box. The rectangular saddle and the roll box are connected by a locking device. The lower roll box is equipped with a double wedge adjustment mechanism including a swing cylinder, a swing arm, a connecting rod, and a wedge. A convexity control device including a hydraulic cylinder, a rack, and a gear piece is provided between the upper support rollers A and B and between C and D. The rolling mill has a good plate shape control effect, and the thickness accuracy of the produced strip steel can reach 0.001mm. The rectangular saddle and the arch are easy to process and have high matching accuracy. The lower roll box is easy to adjust, which can keep the rolling line at a standard height.
