Description

TECHNICAL FIELD

[0001] The utility model relates to steel wire electroplating technical field especially relates to an alkali washing device that improves steel wire quality. BACKGROUND

[0002] The electroplated steel wire forms an oxide skin on the surface after heat treatment, and the oxide skin on the surface of the steel wire needs to be removed completely before electroplating, if there is residual oxide skin, it will cause the problem that the surface of the steel wire cannot be electroplated or the plated layer falls off. In order to better remove the surface oxide skin, the industry commonly uses electrically conductive alkali washing + pickling method, the electrically conductive alkali washing is to horizontally place two anode plates in the electrolytic alkali tank, the alkali solution overflows from the plate and immerses the steel wire, each plate is relatively independent with the overflow alkali solution, the electroplated steel wire passes through the two plates and is immersed in the alkali solution, a certain distance is kept between the plate and the steel wire to prevent the steel wire from contacting the plate and short-circuiting, the alkali solution is used as a conductor to connect the electroplated steel wire and the plate, one plate is an anode and the other plate is a cathode, a loop is formed through the electroplated steel wire. When the inlet plate is connected to the anode, the outlet plate is connected to the cathode, at this time, the current passes through the alkali washing solution to the electroplated steel wire, and from the electroplated steel wire to the cathode, under the action of the current, the electrolytic water releases H + , and the surface of the electroplated steel wire uses H + In the cathode, Fe 3+ →Fe 2+ , thereby changing the properties of the oxide, causing the oxide skin to crack and crack, and facilitating the immersion of the pickling solution under the oxide skin, and the pickling tank can quickly remove the oxide skin on the surface of the high-speed produced steel wire. With the reaction, part of the oxide skin falls on the plate, and at the same time, the cathode and the anode of the plate are exchanged by adjusting the current, a large amount of hydrogen gas generated by the cathode is used to flush away the oxide deposited on the original anode position, and the reaction efficiency of the plate is improved.

[0003] In the existing electroplating assembly line, in order to better arrange different order production specifications, two large modules are generally divided according to the width of the assembly line, the A face close to the operation surface and the B face away from the operation surface, the steel wire specifications of the A / B face are different, and the number of steel wires is the same, generally 40-60 electroplated steel wires are arranged on each face, and the alkali washing is not divided into A / B face, and the current is output by the electric cabinet, when the specifications of A / B face are different, the current deviation of different specifications of A / B face is large, the electrolysis efficiency is inconsistent, the oxide skin of the thick specification steel wire is not broken enough, the acid solution cannot be immersed in the bottom of the oxide layer in the next pickling process, and finally the thick specification steel wire is not cleaned by pickling.
