Description

Technical Field

[0001] The utility model relates to the technical field of steel strip deviation correction, in particular to a deviation correction device for preventing the steel strip from deviating and an acid continuous rolling looper. Background Art

[0002] The looper of the acid continuous rolling mill is used to store materials and buffer the production rhythm. The looper mainly relies on winches, wire ropes and looper cars to store steel strips. At present, the acid continuous rolling looper has a total of six layers of steel strips. The looper is filled with dust and iron sheets on the surface of the hot-rolled coils, resulting in poor working conditions. During the long-term operation of the looper car, the wheels and rails are worn, resulting in unbalanced operation of the looper car. The unbalanced looper car can easily cause the middle two layers of steel strips to deviate, which can seriously affect the normal production of the acid continuous rolling mill. However, since the replacement of the acid continuous rolling looper rails requires a long time to adjust, resulting in high production costs, this application proposes a technical solution to solve how the acid continuous rolling can produce normally after the rails are worn.
