Embodiment 1

[0014] The process tank in the continuous copper plating of the steel strip adopts a closed isosceles trapezoidal tank with a transparent automatic opening observation window, and the tank body is designed as an isosceles trapezoidal tank body above; There are three transparent observation windows that can be opened automatically; a hydrogen concentration alarm is set above the plating tank, and the probe of the alarm is placed in the coating tank; there are emergency air valves on both sides of the tank; Air pipe; air valve, hydrogen concentration alarm are connected with the controller. During the continuous copper plating production process of the steel strip, hydrogen gas will be precipitated at the same time as the cathode discharges, and a hydrogen enriched area will be formed above the plating tank. The alarm probe will detect the concentration of hydrogen in the plating tank. When the hydrogen concentration reaches or exceeds the preset alarm When the value is reached,...

Embodiment 2

[0016] The mother tank of the plating solution is equipped with a sodium carbonate concentration sensor and a sodium carbonate concentration alarm; the sodium carbonate concentration sensor is connected to the sodium carbonate concentration alarm; the sodium carbonate concentration alarm is connected to the controller; connected to the filter pump. The sodium carbonate sensor detects the concentration of sodium carbonate. When the sodium carbonate content exceeds 75g / L, the sodium carbonate alarm sends the signal to the controller, and the controller controls the filter pump to pour the plating solution in the plating solution mother tank into the treatment tank. Sodium carbonate is crystallized by the refrigerator in the treatment tank, and then the plating solution is sent back to the mother tank of the plating solution, and the mother tank of the plating solution returns the plating solution to the plating tank. It avoids the decrease of the current efficiency of the platin...

Embodiment 3

[0018] An infrared probe, a control cabinet, a motor and a deviation-correcting roller are arranged between the continuous copper-plating drying of the steel strip and the coiling machine. The infrared probe is connected to the control cabinet; the control cabinet is connected to the motor; the motor is connected to the deviation-correcting roller. When in use, the infrared probe senses the position of the steel strip, measures the distance from the edge of the steel strip, and transmits the signal to the control cabinet at the same time. The tape machine then completes the tape work.

Abstract

The invention relates to steel band continuous copper plating VI which adopts a cyanation copper plating technique to perform electroplating. The steel band continuous copper plating VI mainly comprises a pretreatment process and a copper electroplating process, wherein the pretreatment process mainly comprises the steps of ultrasonic oil removal, electrolytic oil removal, water washing, activating, water washing and the like; and the electroplating process mainly comprises the steps of copper plating, recycling, water washing and the like. A technical tank in the steel band continuous copper plating adopts a closed transparent simultaneous-gas-discharge isosceles trapezoid tank with openable view windows, wherein the upper part of the tank body is designed as an isosceles trapezoid; three transparent automatic-opening view windows are respectively designed at two slope parts of the tank; a plating solution in the plating tank in steel band continuous copper plating is circulated and filtered by double mother tanks; a pretreatment waste liquid and an electroplating waste liquid in the steel band continuous copper plating are circulated and filtered by three mother tanks, and sodium carbonate is treated on line; a funnel and a filter screen are arranged below a conducting roller for steel band continuous copper plating, and the residual plating solution on the steel band is recovered in an atomization spray mode; and a steel band outlet end of the steel band continuous copper plating is provided with a vacant tank which is about 100mm long, and the residual plating solution on the steel band is recovered in an atomization spray mode.

Description

technical field [0001] The invention relates to the technical field of alkaline copper plating, in particular to continuous copper plating on a steel strip. Background technique [0002] With the development of my country's industry, especially the rapid development of automobile and other industries, the demand for copper and copper products is increasing day by day. However, my country is a copper-poor country. Copper mainly depends on imports. In addition, the price of copper in the world has risen rapidly, which has brought great cost pressure to my country's automobile and other industries. After demonstration and practice, it is feasible to replace copper products with copper-plated steel products in industries such as automobiles and home appliances, and even have better performance than copper in some aspects. Copper-plated steel strips are mainly used to produce help pipes, which are widely used in automobile oil pipes, floor heating pipes, air-conditioning pipes, ...
