The gravity aluminum melting furnace has the effect of integrating feeding, heating and melting, heat preserving, filtering and degassing and is suitable for being used for a melting furnace for casting aluminum alloy.

Description

A kind of gravity melts aluminium stove and molten aluminium method
Technical field
What the present invention proposed is that a kind of gravity of field of metal casting technology melts aluminium stove and molten aluminium method.
Background technology
Molten aluminium stove is the common equipment of used in aluminium alloy casting, and traditional handicraft is continous way, or heat preserving type gravity furnace:
Continous way is divided into the technique of feeding tower+melting chamber+moist closet+liquid taking port; Heat preserving type adopts the technique that aluminium water pours moist closet+liquid taking port into outside adopting; The heat-conduction principle that two kinds of gravity furnaces all adopt, utilizes moist closet to heat and ensures that liquid taking port place temperature can meet liquid taking port temperature of aluminum liquid and meet need of production, finally form product.
The said equipment utilizes a large amount of energy resource consumptions to ensure the high temperature about 750 DEG C of moist closet, conducts to aluminium liquid middle and lower part liquid taking port temperature of aluminum liquid is reached 650 DEG C from aluminium liquid liquid level.Continuously heat, consume mass energy carry out production ensure.
Summary of the invention
In order to overcome the shortcoming that existing molten aluminium stove exists, the present invention proposes a kind of gravity and melting aluminium stove and molten aluminium method.This molten aluminium stove, by arranging moist closet in aluminium liquid melting furnace, arranges filter between moist closet and liquid taking port, by adding aluminium material, fusing, insulation, filtration and degasification, extracting aluminium liquid, using as casting.Solve the technical problem of aluminium liquid heat fused, insulation, filtration and degasification.
The scheme that technical solution problem of the present invention adopts is:
Moist closet is provided with in aluminium liquid melting chamber, moist closet sidewall and upper wall are respectively equipped with smoke dust duct, the first burner, the second burner and the 3rd burner, dog-house is provided with on moist closet top, in moist closet, be provided with aluminium liquid melting channel and adopt liquid mouth outward, between moist closet and liquid taking port, filter is installed, heating rod is equipped with in liquid taking port bottom, and liquid taking port wall is provided with heat-insulation layer, and liquid taking port is built with L shape degasification bar.
In aluminium liquid melting chamber, aluminium material is added by dog-house, then by the first burner, second burner and the 3rd burner light natural gas, natural gas combustion flame heating aluminium material, aluminium material is melted, simultaneously at moist closet inside holding, the waste gas that gas-firing produces is discharged by smoke dust duct, the aluminium liquid that institute's heat fused is also incubated flow in liquid taking port by aluminium liquid melting channel through filter, under the effect of L shape degasification bar, the gas in aluminium liquid is discharged, extract aluminium liquid by liquid taking port and be used for casting, when needs cleaning moist closet, by adopting liquid mouth outward, the aluminium liquid in moist closet is discharged.
Good effect, the present invention has the effect of reinforced, heat fused, insulation, filtration and degasification function integration.The suitable melting furnace application as aluminium alloy casting.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention
In figure, 1. heating rod, 2. the first burner, 3. the second burner, 4. dog-house, 5. melting chamber, 6. moist closet, 7. liquid taking port, adopt liquid mouth 8., 9. the 3rd burner, 10. heat-insulation layer, 11. filters, 12. aluminium liquid melting channels, 13. smoke dust ducts, 14.L shape degasification bar.
Detailed description of the invention
According to the figure, moist closet 6 is provided with in aluminium liquid melting chamber 5, moist closet sidewall and upper wall are respectively equipped with smoke dust duct 13, first burner 2, second burner 3 and the 3rd burner 9, dog-house 4 is provided with on moist closet top, in moist closet, be provided with aluminium liquid melting channel 12 and adopt liquid mouth 8 outward, being provided with filter 11 between moist closet and liquid taking port, heating rod 1 is equipped with in liquid taking port bottom, liquid taking port wall is provided with heat-insulation layer 10, and liquid taking port is built with L shape degasification bar 14.
The course of work of the present invention:
In aluminium liquid melting chamber, aluminium material is added by dog-house, then by the first burner, second burner and the 3rd burner light natural gas, natural gas combustion flame heating aluminium material, aluminium material is melted, simultaneously at moist closet inside holding, the waste gas that gas-firing produces is discharged by smoke dust duct, the aluminium liquid that institute's heat fused is also incubated flow in liquid taking port by aluminium liquid melting channel through filter, under the effect of L shape degasification bar, the gas in aluminium liquid is discharged, extract aluminium liquid by liquid taking port and be used for casting, when needs cleaning moist closet, by adopting liquid mouth outward, the aluminium liquid in moist closet is discharged.
Aluminium liquid runner carries out aluminium liquid balance by gravity, is beneficial to liquid taking port and gets liquid.
Feature:
Install in aluminium liquid liquid taking port bottom and immerse heating rod, utilize heat energy by lower hoist conduction characteristic, carry out bottom-heated, bottom-heated can make liquid taking port aluminium liquid remain at 650 DEG C, after liquid taking port heating, moist closet temperature can be down to 680 DEG C by 750 DEG C, and reduce gas consumption, monoblock cast can consume 15%.
Online except airway dysfunction, compare with former degassing rotor, add degassing effect, separately decrease and pollute because graphite degassing rotor is oxidized the aluminium liquid caused that comes off.Bottom degasification continuously, adopts argon gas, nitrogen inert gas, improves degassing effect, increases 200ppm.
