Abstract
The invention provides a method for recycling a waste aluminum material to manufacture aluminum casting. The method comprises the following steps: a, screening: magnetically separating the waste aluminum material to remove iron, magnetically separating or manually sorting to remove other impurities; and carrying out dehydration and oil removal on the impurity-removed waste aluminum material at a temperature of 300-400 DEG C; b, smelting: weighing and adding crude aluminum into a smelting furnace for being molten into crude molten aluminum at a temperature of 850-950 DEG C, then, adding the waste aluminum material, which accounts for 5-8% of the total mass of the crude aluminum, obtained in the step a into the crude molten aluminum, and stirring and melting to obtain mixed molten aluminum; and c, casting: casting the mixed molten aluminum obtained in the step b into a casting mould to obtain the aluminum casting. The method has the advantages of being simple in process, high in waste aluminum adaptation, low in cost, high in aluminum recovery rate, and the like.
Description
Technical field
The invention belongs to technical field of metallurgy industry, be specifically related to a kind of aluminium scrap material and reclaim the method manufacturing aluminium casting.
Background technology
Aluminium scrap ash is the waste that the waste of electrolytic aluminium factory and various aluminum profile extrusion industry produce, again through secondary trade waste that the recovery operation of aluminium is remaining.This waste contains a certain amount of aluminum contained compound, and its composition and structure is all comparatively complicated, adopts common acid-soluble or that alkali is molten processing method to be difficult to reclaim wherein contained aluminium; And this aluminium scrap ash light weight grain is thin, easily produces floating dust in atmosphere, causes atmospheric pollution and the environmental disruption of surrounding area.And at present, the treatment process of its aluminium scrap ash is mostly adopted to the mode of piling up or burying, like this, again can cause environmental pollution, be unfavorable for environment protection.
Along with society and expanding economy, day by day increase the demand of aluminium, consequent waste-aluminium scrap ash also increases day by day, causes the environmental protection problem of surrounding area to become increasingly conspicuous.For this reason, the effective process for aluminium scrap ash more and more comes into one's own.Therefore, recycling treatment is carried out to aluminium scrap ash, and utilize the research of its production price product more and more to come into one's own.Like this, aluminium scrap ash both can be made to obtain effective resource utilization Appropriate application, the environmental pollution of aluminium scrap ash and a difficult problem for environmental improvement can have been solved again, for the Economic development of society and the fully effectively utilization of resource, there is sizable promoter action.
Summary of the invention
There is provided a kind of aluminium scrap material to reclaim to manufacture the method for aluminium casting to solve prior art problem, the method is simple, make aluminium scrap ash resource obtain the most effectively utilizing.
To achieve these goals, the present invention adopts following technical scheme:
The invention provides a kind of aluminium scrap material and reclaim the method manufacturing aluminium casting, comprise the steps:
A. screen: irony is removed in the magnetic separation of aluminium scrap material, and magnetic separation or hand-sorted remove other impurity; Then to dewater removing the aluminium scrap material after impurity at 300 ~ 400 DEG C oil removing;
B. melting: take primary aluminum throwing and be smelted into raw aluminum liquid at temperature is 850 ~ 950 DEG C to smelting furnace, then add the aluminium scrap material that primary aluminum total mass 5 ~ 8% step a obtains in raw aluminum liquid, stir fusing and obtain aluminum mixture liquid;
C. pour into a mould: the aluminum mixture liquid obtained by step b is poured in mold and obtains aluminium casting.
The material of aluminium scrap described in step a is useless section bar or useless section bar scrap stock.
Stir described in step b as mechanical stirring, induction stirring or permanent magnetic stirring.
Described useless section bar is pie section bar, briquetting section bar, strip section or tubulose section bar.
compared with prior art, the beneficial effect that obtains of the present invention:
1. the present invention adopts magnetic separation to remove irony impurity, can effectively reduce and control the irony content of final cast aluminum-molykote composite material foundry goods, has both been conducive to the extensibility and the mobility that improve cast aluminum-molykote composite material foundry goods, can improve again casting sticking to mould characteristic; And screening can also strengthen the adaptive faculty of reclaiming process to aluminium scrap material in earlier stage, also can by controlling aluminium scrap material moisture, the significantly objectionable constituent hydrogen of reduction finished product.
2. the present invention calculates according to energy conservation, show that in raw aluminum liquid, to add aluminium scrap material that primary aluminum total mass 5 ~ 8% step a obtains stirs fusing to obtain aluminum mixture liquid be the best amount of melting down by test of many times; Because the amount of melting down very little, cannot realize maximum economic benefit, the amount of melting down is too much, can cause again the rising of temperature raising gas consumption, add production cost, cause economic benefit to reduce.Only need to utilize raw aluminum liquid temperature to melt completely according to the best amount of melting down.Go out aluminium link and improve requirement, generally must not go out aluminium too early, prevent Aluminum from shelving and cause calorific loss, but aluminum mixture liquid temp must not lower than 830 DEG C.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but does not limit content of the present invention.
Embodiment
Aluminium scrap material reclaims the method manufacturing aluminium casting, comprises the steps:
A. screen: irony is removed in the magnetic separation of aluminium scrap material, and magnetic separation or hand-sorted remove other impurity; Then to dewater removing the aluminium scrap material after impurity at 300 ~ 400 DEG C oil removing;
B. melting: take primary aluminum throwing and be smelted into raw aluminum liquid at temperature is 850 ~ 950 DEG C to smelting furnace, then add the aluminium scrap material that primary aluminum total mass 5 ~ 8% step a obtains in raw aluminum liquid, stir fusing and obtain aluminum mixture liquid;
C. pour into a mould: the aluminum mixture liquid obtained by step b is poured in mold and obtains aluminium casting.
The material of aluminium scrap described in step a is useless section bar or useless section bar scrap stock.
