For example, the one shown in FIG. 5 is known. According to this method, a positive electrode plate c and a cathode arranged along a longitudinal direction (traveling direction) of the steel strip b are provided on a stainless cold-rolled steel strip b passing through a tank a filled with a neutral salt electrolyte. The scale on the surface of the steel strip b is removed by applying an electrolytic current through the electrode plate d.

The steel strips b are arranged on the upper and lower surfaces along the longitudinal direction, and a power supply voltage e is applied between the positive electrode plates c, c and between the negative electrode plates d, d. Therefore, the upper and lower surfaces of the steel strip b passing between the positive electrode plates c and c are negatively charged, while the upper and lower surfaces of the steel strip b passing between the negative electrode plates d and d are positively charged. As a result, the current of the power source e becomes an electrolytic current from the positive electrode plate c and flows to the negatively charged portion on the surface of the steel strip b, and then flows to the negative electrode plate d side of the steel strip b to reach the positively charged portion, An electrolytic current flows from the positive charging portion to the negative electrode plate d and returns to the power source e. At this time, the positively charged portion of the steel strip b becomes the anode surface, and the scale on the surface of the steel strip b is chemically removed by the progress of the dissolution of the metal or metal oxide and the generation of oxygen gas due to the chemical reaction on the anode surface. It is supposed to be done.

多くの電流が費やされて電流の無駄が発生し、電力の原
単位を悪化させるという問題があった。By the way, when electrolytic pickling is applied to a stainless steel strip, the electrolytic current density applied to the steel strip b is increased within a range satisfying conditions such as use of pickling equipment to improve the pickling ability. I am going to the maximum. However, in the above conventional electrolytic pickling method, the upper and lower fixed electrode plates c, c
Since the steel strip b moves between (d, d) and pickling is performed,
When the electrode length is long, as shown in FIG. 6, a so-called gradient current density distribution is generated in which the electrolytic current density has a gradient in the longitudinal direction of the electrode plates c and d (the positive / negative of the current density in FIG. It represents the direction of flow.) In the case of such a gradient current density, on the high density current side, a large amount of current is consumed for the generation of oxygen gas, which results in a waste of current, which deteriorates the power consumption rate.

を目的とする。Further, there is a problem that unevenness in current density distribution due to the gradient current density causes uneven gloss called an electrolytic pattern on the surface of the steel strip b. The present invention has been made in order to eliminate such inconvenience, and it is possible to suppress the electric power consumption to a low level by making the current density distribution in the longitudinal direction of the steel strip surface uniform, and to form a uniform glossy surface on the steel strip surface. An object of the present invention is to provide a method for electrolytic pickling of a steel strip that can be formed.
