Description

Technical Field

[0001] The present invention relates to the field of copper-clad steel processing, and specifically relates to a copper-clad steel processing device without the participation of acid and alkali. Background Art

[0002] Since pure copper conductors are expensive and galvanized steel has poor corrosion resistance, while copper-clad steel is a new type of bimetallic composite material. It not only has the high strength, excellent elasticity, large thermal resistance and high magnetic permeability of steel, but also has the good electrical conductivity and excellent corrosion resistance of copper. Therefore, copper-clad steel materials are widely used in grounding materials at home and abroad.

[0003] The Chinese invention patent with the application number 201710133600.5 discloses a method for preparing large-diameter tin-copper-steel wire by continuous hot dipping tin. Among them, in the copper casting process of step (2), pickling and alkali neutralization processes are required. The acids and alkalis used in this process will not only pollute the environment, but may also exist on the surface of the steel in small amounts, forming bubbles between copper and steel during copper casting, affecting the reliability of their cooperation. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a copper-clad steel processing device without the participation of acid and alkali, which can improve the quality of finished products, reduce environmental pollution and improve processing efficiency.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: including a first wire unwinding device, a first straightening device, a first polishing machine, a boronizing bath, a first dryer, a first dust collector, a wire drawing machine, a second wire unwinding device, a second straightening device, a second polishing machine, a second dust collector, a copper casting furnace, a traction device, a second wire drawing machine, a third wire unwinding device, a vacuum annealing furnace, and a first wire winding device;

[0006] The coiled steel wire is unwound by the first wire unwinding device, straightened by the first straightening device, polished by the first polishing machine, boronized by passing through the boronizing bath, the liquid carried by the boronized steel wire is dried by the first dryer, the surface of the steel wire is dusted by the first dust collector, and then made into a steel coil wire by the wire drawing machine;

[0007] The steel coil wire is unwound by the second wire unwinding device, straightened by the second straightening device, polished by the second polishing machine, dusted by the second dust collector, and then enters the copper casting furnace for copper casting to form a copper-clad steel blank. The copper-clad steel blank is guided by the traction device and made into a copper-clad steel coil wire by the second wire drawing machine;

[0008] The copper-clad steel coil wire is unwound by the third wire unwinding device, heat-treated by the vacuum annealing furnace, and then wound by the first wire winding device after the copper-clad steel wire is obtained.

[0009] By adopting the above technical scheme, polishing, boronizing, heating and dust removal are used instead. Boronizing can not only demagnetize the polished steel, but also remove most of the waste chips with the boronizing solution, completing the removal of most of the oxide layer. With the subsequent heating and dust removal, the waste chips will not enter the wire drawing machine with the steel. Moreover, the above equipment can reduce the amount of oxide layer removal required before copper casting, so only polishing and dust removal are required to achieve a better oxide layer removal effect, eliminating the "pickling and alkali neutralization" steps in the traditional steps, thereby avoiding the pollution of the environment caused by acids and alkalis, and also avoiding the small amount of acids and alkalis on the surface of the steel, which will form bubbles between copper and steel during copper casting and affect the quality of the finished product.

[0010] The present invention is further configured to include: a fourth wire unwinding device, an ultrasonic device, a film-forming immersion tank, a second dryer and a second wire winding device. The fourth wire unwinding device unwinds the rolled copper-clad steel wire, cleans the copper-clad steel wire with an ultrasonic device, immerses the copper-clad steel wire in a film-forming immersion tank until a nano-oxide protective film is formed, and then dries and solidifies it in the second dryer, and then is wound up by the second wire winding device.

[0011] By adopting the above technical solution and adding a film-forming process, the surface of the copper-clad steel wire can remain unoxidized for a long time after processing, ensuring that the copper-clad steel continues to maintain excellent grounding performance.

[0012] The present invention is further configured such that: the first straightening device comprises a vertical straightening part and a transverse straightening part.

[0013] By adopting the above technical solution, the parts are straightened in two directions, which not only makes the straightening effect better, but also can peel off a large amount of easy-to-peel oxide layer through pressure, and reasonably utilizes the structure to optimize the effect of removing the oxide layer.

[0014] The present invention is further configured as follows: the copper casting furnace is provided with a temperature control module for continuously maintaining a set temperature.

[0015] By adopting the above technical solution, the temperature control module can stably maintain the set temperature, thereby ensuring a stable steel casting effect. BRIEF DESCRIPTION OF THE DRAWINGS
