Abstract
The invention discloses a refining agent for recovering red composition brass, which is prepared by smelting the following ingredients by weight percentage: 8-20% of Na2B4O7, 20-35% of MgF2, 45-70% of Na2CO3, and 1-3% of Y. The refining agent for recovering the red composition brass is low in cost, and service cost, has obvious deoxidation, degassing and impurity removal effects, can effectively purify brass liquid, and improves conductivity of regenerated red brass.
Description
Technical field
The present invention relates to purple composition brass and reclaim refining techniques field, is a kind of refining agent reclaiming for purple composition brass and preparation method thereof specifically.
Background technology
Purple composition brass refers to that copper content is greater than 96% and above copper alloy.The method that fine copper is prepared in the recovery of current purple composition brass is mainly that purple composition brass is first cast to anode copper through pyrogenic attack, and then electrorefining becomes electrolytic copper.Pass through refining, certainly will consume a large amount of energy, relatively by ore smelting, carry out refining, the method of product is produced in regeneration, directly utilize purple composition brass to produce fine copper alloy product by energy-conservation more than 80%, than refining regeneration, produce the method saving energy 50% of product, and electrolytic process environmental pollution is serious.With minimum investment, improve purple composition brass utilization ratio and utilize level, reducing metal loss, reducing environmental pollution, all significant to enterprise, industry, country, society.
No. 1 purple composition brass is mainly copper cash and clean copper pipe and other fine copper block material that clean, alloy-free, uncoated processing fent, conducting plates, diameter are greater than 1.6 millimeters, and copper content is more than 98%, and purity is higher, recycles Maximum Value.Mainly by direct refining removal of impurities, recycle at present, the refining agent that refining removal of impurities is used is mainly the composite refiner that copper boron master alloy or copper phosphorus master alloy and common charcoal form, but impurity-eliminating effect is unsatisfactory, patent documentation CN103146943A discloses a kind of purple composition brass refining agent and preparation method thereof, the purple composition brass refining agent of the present invention is a kind of multicomponent alloy, and its chemical composition (weight percent) is: B=3.5～5.5%; Mg=3.5～5.0%; Ce=8.0～11.5%; Pr=6.0～8.0%; Y=6.0～8.0%, the total content of rare earth element ce, Pr, Y is 20.0～27.5wt%, surplus is Cu; Can effectively remove Ni, clearance can reach more than 68%.But this refining agent has been used the rare earth metal that a large amount of prices is high, and use cost is high, utilization and extention is worth limited.
Summary of the invention
The object of the invention is for above-mentioned deficiency of the prior art, a kind of refining agent reclaiming for purple composition brass and preparation method thereof is provided.
The object of the invention is to be achieved through the following technical solutions:
The refining agent reclaiming for purple composition brass, is founded and is formed by Sodium Tetraborate, magnesium fluoride, sodium carbonate and yttrium powder, and the weight percent of each component is: Na

The present invention has following outstanding beneficial effect:
Purple composition brass of the present invention reclaims refining agent due to the absorption in refining process and chemosynthesis, have obvious deoxidation, degasification, go deimpurity effect, thereby purifying copper liquid effectively improves the conductivity of regeneration red copper; Meanwhile, refining agent cost of the present invention is low, manufactures use cost little, has very high economic worth.
