Technical field
The present invention relates to industry metallurgy smelting equipment field, more particularly to a kind of to smelt for various special alloys
Stove interior-heat convert formula arc metallurgy equipment.
Background technology
Metallurgical industry, refer to exploration to metalliferous mineral, exploitation, it is selected, smelt, and rolling become a useful person
Industrial department, metallurgical industry are important raw and semifinished materials industries departments, provide metal material for each department of national economy
Material, and the material base of economic development, metallurgical industry can divide ferrous metals industry and colored metallurgical industrial,
Iron and steel industry refers mainly to the production for including the pig iron, steel and ferroalloy (such as ferrochrome, ferromanganese etc.), nonferrous metallurgy
Refer to that the latter includes the production of remaining all various metal, in addition metallurgy can be divided into metallurgy of rare metal industry and
Powder metallurgy industry, the metallurgy of many of special alloy smelt particularly important.
The metallurgical smelting of traditional various special alloys, it is desirable to have the heat outside a kind of stove converts technique, for example：Silicon
The smelting of " double zero ferrum " of ferrum series, " middle low Carbon Manganese ", and industrial silicon smelting etc., be required for closing
In golden smelting process when tapping a blast furnace, be blended into a number of flux in ladle, purification alloy or increase is closed
The trace element of gold, and the flux that heat is converted, are by being manually quantitatively added in ladle with spade, in batches
With molten iron mixing, while a certain amount of compressed air will be also blown in the bottom connecting tube of ladle entering
In the middle of molten iron, along with the chemical reaction that molten iron is violent during heat is converted, there is substantial amounts of gas to produce, make
Into air pollution, while also resulting in the molten iron splash in ladle, the ladle bottom of technique is converted due to smelting heat
There is the mouth of pipe led in ladle in portion, needs to be blown into the compressed air of certain pressure, it is ensured that the change of molten iron
Reaction is learned, pressure is excessive or too small being all likely to result in below molten iron is flowed out and splash above, and heat converts process
Middle ladle is the motor performance in the middle of overhead traveling crane hanging, and ladle bottom is also associated with the pipeline ventilated, in ferrum
The factor such as easily break in water casting process, also control difficulty is increased to equipment operation operation, if control
The bad damage for often resulting in equipment, burn out, the outflow of molten iron causes the scald of personnel, causes whole iron clad
Water landing become waste product, increased serious potential safety hazard to operator, due to molten iron splash also simultaneously
The splash of special alloy product, outflow is caused to cause the waste of product, while the air also resulted in Factory Building is dirty
Dye the Technology difficult problem for puzzlement special alloy smelting industry.
The content of the invention
It is an object of the present invention to provide a kind of stove interior-heat smelted for various special alloys converts formula electric arc smelting

Smelt all operationss that heat converts technique, the molten iron after heat is converted, by tapping a blast furnace for the side-lower of the body of heater of electric furnace 6
Mouthful, after outflow, ladle is directly entered, pouring practice is carried out into finished product.
The invention has the beneficial effects as follows, simple structure is novel in design, practical reliable, simple to operation,
Steel pipe opening top in coreless armature 5 during not working is blocked, air can be avoided to enter by this equipment,
The too early scaling loss of furnace lining is prevented, when heat being carried out to the inside of electric furnace 6 and converting, due to having yet suffered from above molten iron
Furnace charge, formed closing space, molten iron will not splash, effectively can prevent Injection In Molten Iron spatter loss lose and various harm,
Reduce air pollution, the design of the tapping hole of the side-lower of the body of heater of electric furnace 6, after the completion of can convert heat
Molten iron, directly imports ladle by tapping hole, carries out finished product cast, main pipeline 4, branch by ladle
Heat can be converted flux, compressed air and be led in electric furnace 6 by the design of pipeline, coreless armature 5 and its inside
The design of steel pipe is set, the heating surface (area) (HS of electrode paste can be effectively increased, electrode paste is fully sintered, disappeared
Except soft disconnected phenomenon, using the construction featuress of steel pipe, the volatile matter of electrode paste smoothly can be discharged, improve electricity
The sintering quality of pole paste, in stove, smelting Continuous Heat converts technique makes whole smelting process just convert technique with respect to stove exterior-heat
More perfect, the heat for meeting special alloy smelting converts the operation needs and smelting requirements of technique, while reducing
Stove exterior-heat converts the various drawbacks of technique, improves the safety in smelting process, decreases product molten iron
Splash loss, saved due to the energy that consumes in smelting of molten iron of splash loss, shortened and operated
Journey, eliminates operator near deathtrap, the potential safety hazard for being formed, and reduces connecting line, pressure
Installing and using for the equipment such as the nozzle of contracting air, improves the controllability and stability of equipment operation.
