Abstract
A regenerated aluminum high-efficiency iron-removing device and a method thereof are characterized in that: 1) two hollow stirring rods are selected, the two stirring rods are allowed to be welded in parallel and be fixed on an iron-made sealed container, a water cooling circulation system is formed in the cavities of the stirring rods and the interior of the sealed container, the strong-magnetism iron-removing device with water cooling is prepared, and the exterior is coated with heat resistant asbestos cloth; 2) when iron removal of a regeneration aluminum molten liquid is required, the water cooling circulation system of the strong-magnetism iron-removing device is started, iron in the molten aluminum is absorbed and cleared up by utilizing a magnetic force of a strong magnet during stirring; and 3) the strong-magnetism iron-removing device can be recycled. The method is simple, is convenient for practical operation, good in iron removing effect and low in cost, and quite easily removes the impurity iron by utilizing magnetism adsorption. Moreover, with adopting of the water cooling circulation system, the magnetism of the magnet is ensured to not lose due to the high temperature, so that the strong-magnetism iron-removing device can be recycled.
Description
Technical field
The present invention relates to aluminium smelting technique field, be specifically related to the strong magnetic deironing apparatus of a kind of secondary aluminum and method.
Background technology
Secondary aluminum is the indispensable resource of aluminium industrial sustainable development, compare with aluminum production, secondary aluminum per ton can be saved the energy and reach 95%, the noxious emissions such as carbonic acid gas greatly reduce, not only save energy, environment purification, the production cost that can also greatly reduce Al-alloy products, has good Social benefit and economic benefit.Whole world secondary aluminum accounts for 45% of aluminium market aggregate demand, the raw material sources of aluminium scrap regeneration are complicated, of a great variety, inevitably can bring the inclusion of some amount into, especially the content of iron is higher, easily cause the defects such as generation in aluminium alloy cast ingot is loosened, slag inclusion, very large on the use properties impact of aluminium, high ferro aluminium can not directly be used.Secondary aluminum is produced in aluminium alloy process, and deironing is very important step, and traditional method is to carry out deironing by adding iron removing reagent, and cost is high, has again other material and generates.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of technique simple, the strong magnetic deironing apparatus of easy to operate secondary aluminum and method, cardinal principle is stronger than iron according to the reductibility of aluminium, in molten aluminum liquid, impurity iron exists with simple substance form, thereby utilize magnetic absorption to be very easy to remove impurity iron, can not produce other materials, and with low cost.Consider the volatile magnetic of high temperature magnet, take water-cooled assurance magnet magnetic not lose.
Technical problem to be solved by this invention realizes by the following technical solutions:
The strong magnetic deironing apparatus of secondary aluminum and a method, comprise following methods step:
1) choose two hollow agitator arms, allow two agitator arms walk abreast and be fixedly welded on an iron sealed vessel, agitator arm cavity communicates with sealed vessel;
2) on iron sealed vessel, there is a sealing cover that can conveniently open and close, by sealing cover, a strong magnet or electro-magnet are inserted in iron sealed vessel;
3) with heat-resisting woven asbesto, agitator arm cavity and sealed vessel are wrapped up;
4) two of agitator arm cavitys connect respectively a water injection pipe and a rising pipe, at agitator arm cavity and sealed container interior, form a water-cooling circulating system, make one with the strong magnetic deironing apparatus of water-cooled;
5) while needing deironing, open the water-cooling circulating system of described strong magnetic deironing apparatus, the agitator arm of hand-held strong magnetic deironing apparatus extend into iron sealed vessel one end in melted aluminium liquid and stirs, and utilizes the magnetic force of strong magnet by the iron adsorption removal in aluminium liquid;
6) after stirring finishes, take out strong magnetic deironing apparatus, after strong magnetic deironing apparatus is cooling, close water-cooling circulating system, this device can be recycled;
7) when the impurity iron filings that adsorb on strong magnetic deironing apparatus too much need to be removed, can be when stirring end, first close water-cooling circulating system, from molten aluminum liquid, take out again strong magnetic deironing apparatus, while hot the woven asbesto of strong magnetic deironing apparatus outer wrap is dismantled rapidly, leave concentratedly, accumulate and again drop into molten bath when more and carry out circulation deferrization, woven asbesto fusing is removed with slag form.
Described strong magnet inside is densely covered with the water stream channel being interconnected, and is filled with water coolant in water stream channel, for strong magnet is carried out to cooling process, guarantees that its magnetic is not subject to temperatures involved and disappears.
The invention has the beneficial effects as follows: the inventive method is simple, be convenient to actually operating, utilize magnetic absorption to remove impurity iron and be very easy to, good iron removal effect, can not produce other materials, with low cost.And the water-cooling circulating system of taking guaranteed magnet magnetic not Yin Gaowen lose, strong magnetic deironing apparatus can be recycled.
