帯及び鋼板の片面酸洗法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for surface pickling of steel sheets, which is a method for single-sided pickling of copper strips and steel sheets, in which only the lower surface of the copper strip or steel sheet is continuously pickled, and no acid solution is attached to the upper surface. Regarding the law.

せるシャワー・ブラッシング法等がある。Surface pickling of steel plates is widely used for surface treatments such as degreasing, mill scale removal, and rust removal. As a pickling method for steel plates with an acid solution, there is an immersion method in which the steel plate is immersed in an aqueous solution of acids such as sulfuric acid, hydrochloric acid, phosphoric acid, etc. in a container, and the steel plate surface Km
There is a shower brushing method, etc. in which the liquid is distributed and supplied by a spray and then diffused by a rotating brush.

た。However, when using these pickling methods to pickle only one side of a steel plate, the one side that does not require pickling treatment is covered in advance with acid-resistant paint or an acid-resistant film such as vinyl. It is often necessary to prevent the acid solution from adhering to the steel plate, or to remove the acid solution adhering to one side after pickling treatment to prevent discoloration of the steel plate due to acid solution erosion. In short, the processing capacity was poor, and the acid solution was not wasted.

所の手入等の工数が省力された。As explained above, in the present invention, a rotatable endless magnetic belt, which has acid resistance, flexibility, and magnetic force, is brought into close contact with a certain circumference of both sides of a copper strip or a steel plate. Pickling is carried out by supplying an acid solution to the lower surface of the copper strip or steel plate using an acid solution supply means while rotating at the same speed as the transfer speed of the copper strip or steel plate. Unnecessary acid solution adhesion to the top and side surfaces is reliably prevented, and man-hours such as measures for preventing acid solution adhesion before pickling and maintenance of areas where acid solution is attached after pickling are saved.
