Description
Technical Field
The utility model relates to the technical field of continuous rolling pickling of plates, in particular to pickling equipment for a continuous rolling process of plates.
Background
In the process of continuously casting and rolling a hot rolled sheet, as the continuous casting speed is high, the floating of inclusions in steel is difficult, molten steel in a crystallizer is easy to disturb, so that casting powder is wound on the continuous casting surface and under the surface, and surface defects such as slag inclusion, inclusions and the like are formed on the surface of the hot rolled sheet. If the surface defects remain on the surface of the steel plate after hot rolling, the surface defects are generally removed by adopting an acid washing method, and a lot of slag inclusion and impurities can be removed along with liquid flow by chemical reaction with acid liquor or dissolution in the acid liquor. However, surface defects such as slag inclusion and impurities, etc. remained on the surface of the pickled steel strip are insoluble in acid liquid, and cannot be removed by pickling. If the residues cannot be removed during pickling, the surface quality of the pickled steel strip product produced by the subsequent cold rolling process is very harmful, especially in the production of products with high requirements on surface quality, such as CGL production lines, the slag inclusion and the impurities are further pressed into the pickled steel strip substrate after rolling by a cold rolling mill to form surface defects which are difficult to remove, and serious damage is caused to subsequent cold rolling process equipment, such as damage to rolling and the cold rolling mill thereof, therefore, we propose a pickling equipment for the continuous rolling process of plates.
