Abstract
The invention discloses a method for producing anaerobic polished copper bars by waste red copper wires. The method includes: adding wood charcoal into smelting liquid according to a mass ratio of 1:0.012 during smelting, and using carbon in the wood charcoal as reducing agent to reduce copper oxide into copper at high temperature, wherein a reaction equation is expressed as CuO+C=Cu+CO2. The method successfully replaces electrolytic copper with waste red copper wires to produce the anaerobic polished copper bars. Production cost is lowered by more than 20%, energy conservation and environment protection area achieved, and social benefit and comprehensive economic benefit are increased.
Description
Technical field
The invention belongs to the technical field of nonferrous materials deep processing, relate to anaerobic glitter copper lever production method, more particularly, the present invention relates to the anaerobic glitter copper lever production method that the useless red copper wire of a kind of usefulness is made raw material.
Background technology
The anaerobic glitter copper lever is the upstream product of making electric wire and high frequency resistance welding copper cash, requires electric conductivity high, does not allow to contain other metallic impurity such as iron, and anaerobic, so this product is made raw material with electrolytic copper always.
A large amount of useless red copper wires are arranged on the material market now, also fully rationally do not utilized.If can directly do raw material with useless red copper wire, production anaerobic glitter copper lever will reduce production costs more than 20%.
Summary of the invention
The invention provides the useless red copper wire of a kind of usefulness and make the anaerobic glitter copper lever production method of raw material, its objective is to reduce production costs.
To achieve these goals, the technical scheme taked of the present invention is:
The useless red copper wire of usefulness provided by the present invention is made the anaerobic glitter copper lever production method of raw material, described production method is in fusion process, be 1: 0.012 ratio in mass ratio, in melting liquid, add charcoal, utilize in the charcoal carbon to make reductive agent, under the high temperature copper oxide reduction is become copper, its reaction formula is CuO+C=Cu+CO
2
Described production method is in fusion process, adds an amount of plant ash at the upper layer of melting liquid and makes sorbent material.
In described production method, adopt UPCAST technology and bull take-up technology to produce oxygen-free copper bar.
The diameter of described oxygen-free copper bar is φ 17mm.
Described production method is: adopt three roller Y-series copper bar tandem rolling units, oxygen-free copper bar is carried out continuous rolling.
The present invention adopts technique scheme, has successfully realized substituting electrolytic copper with useless red copper wire, produces the anaerobic glitter copper lever, and not only production cost has reduced more than 20%, and has obtained the effect of energy-saving and environmental protection, has improved social benefit and overall economic efficiency.
Description of drawings
The below is briefly described the expressed content of the accompanying drawing of this specification sheets and the mark among the figure:
Fig. 1 is the structural representation of the three-roll rolling that adopts among the present invention.
Be labeled as among the figure:
1, roll, 2, the copper bar.
Embodiment
The below contrasts accompanying drawing, and the description by to embodiment is described in further detail the specific embodiment of the present invention, to help those skilled in the art inventive concept of the present invention, technical scheme is had more complete, accurate and deep understanding.
The present invention is the anaerobic glitter copper lever production method that the useless red copper wire of a kind of usefulness is made raw material, and the gordian technique that the present invention makes raw material production anaerobic glitter copper lever with useless red copper wire is deoxygenation, removal of contamination and the technique such as rolling.
In order to solve the problem that prior art exists and to overcome its defective, realize the goal of the invention that reduces production costs, the technical scheme that the present invention takes is:
The useless red copper wire of usefulness provided by the present invention is made the anaerobic glitter copper lever production method of raw material, described production method is in fusion process, be 1: 0.012 ratio in mass ratio, in melting liquid, add charcoal, utilize in the charcoal carbon to make reductive agent, under the high temperature copper oxide reduction is become copper, its reaction formula is CuO+C=Cu+CO
2
Aforementioned production method is in fusion process, adds an amount of plant ash at the upper layer of melting liquid and makes sorbent material.
Because fusing point is higher than copper to the proportion of the impurity such as iron (ferric oxide) less than copper, after copper dissolves, all floats on copper liquid.The main component of plant ash is salt of wormwood, belongs to salt of weak acid, and under the dual function of chemistry and physics, it is removed with all dirt secure bond together smoothly.
In described production method, adopt UPCAST technology and bull take-up technology to produce oxygen-free copper bar.
The diameter of described oxygen-free copper bar is φ 17mm.
As shown in Figure 1, described production method is: adopt three roller Y-series copper bar tandem rolling units, oxygen-free copper bar is carried out continuous rolling.
Owing to being three rolls 1, copper bar 2 is in the three dimensional stress state all the time in deformation process, and the unrestricted spread of copper bar 2 is played certain effect of contraction, and copper bar 2 deflections are large, is better than two rollers along the distribution of the compressive stress of rolling direction.Density and the conductive capability of finished product bar are significantly improved, the surface color light.
By technique scheme, realized that successfully substituting electrolytic copper with useless red copper wire produces the anaerobic glitter copper lever, not only production cost has reduced more than 20%, and has realized the purpose of energy-saving and environmental protection.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
