Problems solved by technology

The disadvantages of this structure are: on the one hand, due to the large length of the electrolytic cell, a very large space is required; on the other hand, the length of the cell body is limited, and the time for the steel strip to pass through the cell body is short, and the effect is often not good.
"This patent not only has a complex structure, but also adds many new processes, which obviously increases the production cost.

Abstract

The invention discloses a neutral salt electrolytic cell which comprises a cell body and a cell cover. Wringing rollers are arranged on the two sides of the cell body, a plurality of protruded portions are arranged on the bottom of the cell body, a plurality of immersing rollers are further arranged in the cell body, and the heights of the immersing rollers are different. Band steel is driven by the wringing rollers to move along the immersing rollers, a plurality of electrode plates are arranged on the two sides of the band steel, and the electrode plates are connected with a power supply. The neutral salt electrolytic cell can deeply clear the surface of the band steel, the surface of the manufactured band steel is smooth and free of impurities, and the band steel with the more excellent surface can be obtained.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to an electrolytic cell. Background technique [0002] On the surface of the cold-rolled steel strip of stainless steel, since the oxidation annealing process will generate scale, it is necessary to remove impurities such as scale on the surface of the strip steel; in production practice, a neutral salt electrolytic cell is generally used to solve this technical problem. The usual electrolytic cell structure is a flat-bottomed cell, and the steel strip moves from one end to the other. During this process, the neutral salt (sodium sulfate) solution injected into the cell, the electrode plate, and the strip steel form an electrochemical circuit. , so as to remove impurities such as iron oxide scale on the surface of the strip. The disadvantages of this structure are: on the one hand, due to the large length of the electrolytic cell, a very large space is required; on the other hand, the leng...
