Embodiment 1

[0015] This embodiment is used to illustrate a steel strip electroplating tank for Bondi pipes provided by the present invention.

[0016] (1) Pretreatment tank

[0017] (1) Hot water washing tank: Bring the 200mm wide steel into the hot water at 70-80°C. The size of the tank body: length 6000mm, width 1800mm, height 500mm.

[0018] (2) Ultrasonic degreasing tank, ultrasonic degreasing cleaning agent, the concentration is 5%, the temperature is 40 ~ 50 °C, the ultrasonic frequency is 25 kHz, the size of the tank body: length 6000mm, width 1800mm, height 500mm;

[0019] (3) Electrolytic degreasing tank: immerse the steel strip treated in step (2) into the electrolytic degreasing solution, the temperature of the alkali solution is 60-80°C, and the current density is 8-10A / dm2. Anode degreasing for 15s (after degreasing, use low chloride ion water or pure water with a concentration below 600ppm for cleaning).

Abstract

The invention discloses a steel strip electroplating process tank for a band pipe. The tank is characterized in that a steel strip is electroplated in an S form; empty grooves are respectively formed in the left and right two sides of the tank; separation plates are arranged in the empty grooves; high-pressure nozzles are arranged above and below two sides of each separation plate; the nozzle can clean the steel strip up and down by an angle of 45 degrees; the empty grooves adopt a gas knife formed through high-pressure gas generated by a gas pump to clean the steel strip before copper plating; the empty grooves adopt high-pressure water spraying after copper plating; an electric conducting roller is arranged out of the plating tank, and consists of a rubber roller and a steel roller; the steel roller can be used for conducting electricity; the rubber roller rectifies the steel strip; and an openable transparent plating tank cover is arranged above the plating tank. In the steel strip electroplating process tank, the high-pressure water washing and the gas knife in the two empty grooves are combined to clean the steel strip, so that the cleanness is largely increased before the steel strip enters plating liquid, and the product quality is improved; and the S-shaped steel strip saves the cost by about 1 / 3.

Description

technical field [0001] The invention relates to a steel strip electroplating process tank for Bondi pipes, specifically relating to the technical field of continuous electroplating of steel strips. . Background technique [0002] Bondi tubes are mainly produced by copper-plated steel strips, and are widely used in automobile oil pipes, floor heating pipes, air-conditioning pipes, etc. Cyanide copper plating can obtain a dense, smooth, and well-bonded coating, so the continuous copper plating of steel strips adopts the cyanide copper plating process. Although the country has clearly eliminated the cyanide process, no alternative process has been found so far, and because Widely used in precision electronic instruments, precision instruments, aerospace and other fields, it can only be deferred and eliminated. Cyanide copper plating is the most widely used and earliest copper plating method, but most of the continuous copper plating process tanks for steel strips can only pro...
