Abstract
The invention discloses a method for preparing an aluminum ingot using waste aluminum as a raw material. The method specifically comprises the following steps: an ash collector is arranged beside a conventional smelting furnace; a raw material is pressed to a block shape in production; then, the raw material pressed to the block shape is put into the smelting furnace; meanwhile, a refining agent, a large sand agent, coal slag and sodium silicate are filled and uniformly mixed until all the raw materials are totally dissolved to obtain molten aluminum; on management, the ash collector is used for picking ash in the molten aluminum to guarantee the purity improvement of the molten aluminum; and finally, the molten aluminum is put into a mold, and is cooled to obtain a finished aluminum ingot. Through the method, the raw material is pressed to the block shape, is put into the smelting furnace, and is not liable to be oxidized, so that the recovery rate of the aluminum ingot is improved. The ash collector is used for collecting the ash, so that the ash can be precisely collected, the molten aluminum and the ash can be clearly separated, the collected ash contains no molten aluminum, the molten aluminum contains no ash, nothing is wasted, the purity of the molten aluminum is kept, and the preparation of the aluminum ingot with high quality is guaranteed. The prepared aluminum ingot is high in percentage to 8.8-9%.
Description
Technical field
The invention belongs to a kind of preparing technical field of aluminium ingot, being specifically related to a kind of is the method that aluminium ingot prepared by raw material by aluminium scrap.
Background technology
Aluminium is a kind of silvery white metal, and in the earth's crust, content is only second to oxygen and silicon comes the 3rd.The density of aluminium is less, is only 34.61% of iron, 30.33% of copper, therefore also referred to as light metal.Aluminium is that output and consumption are all only second to the non-ferrous metal of iron and steel in the world.The density of aluminium only has 2.7103g/cm3, is about about 1/3 of steel, copper or brass density.Because the material of aluminium is light, be therefore usually used in manufacturing the land, sea and air vehicles such as automobile, train, subway, boats and ships, aircraft, rocket, airship, increase loading capacity to alleviate deadweight.
At our daily industrial raw material aluminium ingot, should cry " remelting aluminium ingot " by national standard (GB/T 1196-2008).The production of aluminium ingot is made up of production links such as the electrolysis of bauxite exploitation, alumina producing, aluminium.
The production raw material mainly bauxite of aluminium ingot, distributes fewer due to bauxite resource, so, not that place can produce aluminium ingot.And utilize the aluminium scraps such as pop can for raw material production aluminium ingot, can turn waste into wealth, its meaning is very great.
Traditional utilize the aluminium scraps such as pop can for its method of raw material production aluminium ingot be that in high temperature environments, pop can easily produces oxidation by raw material if pop can is single input smelting furnace, the rate of recovery is not high.Meanwhile, traditional production technique takes manually to adopt ash, and such technique one adopts ash totally, and containing lime-ash in aluminium liquid, the quality of ingot aluminum prepared is unstable; Two is that adopted thing contains a large amount of aluminium water, significant wastage raw material; Three is that labour intensity is high, there is potential safety hazard.
Utilize traditional method to produce, the aluminium ingot product obtained becomes number to only have 7 ~ 8 one-tenth.
Summary of the invention
Object of the present invention be exactly overcome prior art processes deficiency and provide brand-new a kind of be the method that aluminium ingot prepared by raw material by aluminium scrap.Specifically comprise: be provided with on the smelting furnace side of routine and adopt grey machine, bulk will be pressed into during production, then throw in smelting furnace by being pressed into block raw material, drop into refining agent, large sand agent, cinder, water glass simultaneously, then carrying out stirring until various raw material dissolves to obtain aluminium liquid completely, management is utilize to adopt grey machine and carry out fishing for the lime-ash in aluminium liquid, ensures that aluminium liquid purity improves, finally aluminium liquid is placed in mould, makes aluminium liquid cooling but obtain finished product aluminium ingot afterwards.
The present invention is achieved through the following technical solutions:
Be the method that aluminium ingot prepared by raw material by aluminium scrap, be in technical scheme to comprise the steps:
1, device layout: conventionally build smelting furnace, and be provided with on smelting furnace side and adopt grey machine.
2, feedstock capture: the aluminum dross of collection containing aluminium component, pop can, aluminium alloy are raw material.
3, Feedstock treating: above-mentioned raw materials is pressed into bulk.
4, feed intake: conventionally the temperature of smelting furnace is brought up to the temperature needed for smelting aluminum liquid, then throw in smelting furnace by being pressed into block raw material, drop into together according to the proportioning of following various raw material when feeding intake, above-mentioned aluminium scrap 1 ton, refining agent 8 kilograms, large sand agent 8 kilograms, cinder 25 kilograms, water glass 5 kilograms.
5, melting: after above-mentioned aluminium scrap, refining agent, large sand agent, cinder, water glass are put into smelting furnace, carry out stirring until various raw material dissolves to obtain aluminium liquid completely.
6, manage: utilization is adopted grey machine and carried out fishing for the lime-ash in aluminium liquid, ensure that aluminium liquid purity improves.
7, finished product: be placed in mould by aluminium liquid, makes aluminium liquid cooling but obtain finished product aluminium ingot afterwards.
Tool of the present invention has the following advantages:
What 1, the present invention carried is the method and measure uniqueness that aluminium ingot prepared by raw material by aluminium scrap, easily implements.
2, by implementing the present invention, raw material is pressed into bulk, after smelting furnace thrown into by raw material, raw material is not easy oxidation, improves the rate of recovery of aluminium ingot.
When 3, manually adopting ash (burner ash), the burner ash that institute adopts, often containing a large amount of aluminium water, if be not used to collected burner ash, then produced and wastes greatly.By implementing the present invention, be provided with on smelting furnace side and adopt grey machine, and carry out adopting ash by adopting grey machine, can to gather accurately lime-ash, and aluminium water be separated with lime-ash clear, the lime-ash adopted without aluminium water, and also without lime-ash in aluminium water, neither waste, also maintain the purity of aluminium liquid, guarantee to prepare high-quality aluminium ingot.
4, utilize traditional method to produce, the aluminium ingot product obtained becomes number to only have 7 ~ 8 one-tenth.By implementing the present invention, various proportioning raw materials is scientific and reasonable, and measure in production management of adding is unique, so the aluminium ingot prepared becomes number high, can obtain 8.8 ~ 9 one-tenth.
5, by implementing the present invention, the quality of ingot aluminum prepared is superior, and manufacturing enterprise makes a profit abundant.
6, by implementing the present invention, can the development of evil in febrile disease filter residue, aluminium alloy, pop can etc. discarded in a large number, make refuse reclamation, resource continuous utilization, then that the bauxite resource preparing aluminum products at present lacks day by day, aluminum products are worth more and more higher meaning today is very great.
