Efficient cold-rolled steel pickling device for shear blade production

Abstract

The invention relates to the technical field of cold-rolled steel production, in particular to an efficient cold-rolled steel pickling device for shear blade production. The device comprises a box body, an acid liquor tank is formed in the box body, a liquor outlet is formed in the middle of the inner bottom wall of the acid liquor tank, a steel inlet is formed in the middle of the left side of the box body, a steel outlet is formed in the position, corresponding to the steel inlet, of the right side of the box body, an observation opening is formed in the middle of the upper end of the front face of the box body, a control box is fixed to the position, located below the observation opening, of the front face of the box body, a transmission assembly is arranged in the box body, the transmission assembly comprises a first transmission roller set, a second transmission roller set and a guide roller set, a cleaning assembly is arranged in the box body, and the cleaning assembly comprises two fixing blocks. By arranging a filter assembly, acid liquor can be filtered, the purity of the acid liquor can be improved, meanwhile, a filter plate can be replaced without affecting the pickling process, and the filter efficiency of the filter plate to the acid liquor can be improved.

Description

technical field [0001] The invention relates to the technical field of cold-rolled steel production, in particular to a high-efficiency cold-rolled steel pickling device for cutting edge production. Background technique [0002] Pickling is an important link in the production process of cold-rolled steel strips. Pickling is the process of removing the oxide scale on the metal surface by chemical methods. Hydrochloric acid is usually used, so it is also called chemical pickling. [0003] At present, after the steel strip is produced, it is necessary to pickle the steel strip through a pickling device. During the pickling process of the steel strip, a large amount of colored oxides will be produced, and these oxides will be mixed in the acid solution. The existing The pickling device does not have the function of filtering the acid liquid. If the oxides in the acid liquid are not filtered and removed for a long time, the purity of the acid liquid will be reduced, thereby reduc...
