Description
Technical field
A kind of Bundy tube continuous copper-plating of steel strip technique, is specifically related to the technical field of continuous steel strip electroplating.
Background technology
What Bundy tube was mainly manufactured by steel band copper facing, it is commonly utilized in automobile oil pipe, floor heating pipe, air-conditioner pipe etc.
Aspect.Cyanide electroplating can obtain the good coating of fine and close, smooth, adhesion, so continuous copper-plating of steel strip uses cyanide electroplating
Technique, although the clearly superseded cyanidation technology of country, but the technique of replacement is not found till now, and because it is widely used in essence
The fields such as close electronic instrument, precision instrument, Aero-Space, can only delay to eliminate.
According to documents, steel band is dropped in from a coating bath into can take plating solution out of during next coating bath
Outside coating bath, the waste of plating solution can be so caused, because plating solution is poisonous, can also polluted, be unfavorable for clean manufacturing.While steel band
Surface can adhere to all kinds of impurity and dirt, if all kinds of impurity and dirt are brought into next operation and can pollute plating solution and influence plating
Layer quality, it will cause the appearance of substandard product.In present invention, during copper facing, the water after atomizing spray cleaning
Female groove is flowed into using the high potential difference of room groove and female groove, and plating solution is transmitted back to coating bath using filter pump；Plating solution waste water passed through
Filter pump enters closed processes groove, and the plating solution after treatment is transmitted back to female groove by filter pump, and female groove conveys plating solution by filter pump
To copper plating groove, realize the online treatment of sodium carbonate and recycle.When running into the emergency cases such as power failure, the plating solution in copper plating groove
Flow into closed processes groove by female groove under gravity to store, it is therefore prevented that the waste of plating solution.Conductive rollers are carried out to spray clearly
Wash, and rinse water recycled, the liquid in female groove is the plating solution for being in saturation state, if lack it is a certain from
Son, can add in closed processes groove, be transported in female groove, then be transmitted back to coating bath by filter pump, at the same steel band be it is S-type walk
To saving production line cost about 1/2nd.
