Problems solved by technology

The traditional method has strict requirements on the shape of the incoming steel plate. If the cross-sectional size of the strip changes greatly in the length and width directions, the traditional deviation correction method cannot correct the deviation of the strip steel to meet the requirements of the rolling mill.

Abstract

The invention relates to a deviation rectification device. A piston rod of a driving side hydraulic cylinder extends in the longitudinal direction of a first frame, and then is connected with a first bearing block, a piston rod of an operating side hydraulic cylinder extends in the longitudinal direction of a second frame, and then is connected with a second bearing block, one end of an upper working roll is connected with the first bearing block, the other end of the upper working roll is connected with the second bearing block, at least two first annular protrusions are arranged on the circumferential surface of the upper working roll, the surface of each first annular protrusion is an arc-shaped surface, a third bearing block is fixed to the first frame, and is arranged below the first bearing block, a fourth bearing block is fixed to the second frame, and is arranged below the second bearing block, one end of a lower working roll is connected with the third bearing block, the other end of the lower working roll is connected with the fourth bearing block, at least two second annular protrusions are arranged on the circumferential surface of the lower working roll, and the surface of each second annular protrusion is an arc-shaped surface. The deviation rectification device achieves deviation rectification on the situation that the dimensions of fed steel plates are not strictly required.

Description

technical field [0001] The invention relates to the technical field of strip steel hot rolling production lines, in particular to a deviation correction device. Background technique [0002] In recent years, with the rapid development of hot rolling technology, the rolling speed has been continuously increased, and the production capacity requirements of the rolling line have become higher and higher. technology. In the hot rolling production line or the new thin strip continuous casting and rolling production line, the shape of the thin strip steel plate is poor, and the cross-sectional dimensions in the two directions of length and width are inconsistent, often irregular, and the thin strip steel needs to be corrected before entering the rolling mill. Real-time deviation correction ensures that the strip enters the rolling mill smoothly for normal rolling. [0003] For users, they do not want a very complicated rectification device, so they require a rectification device...
