Description
Technical field
The present invention relates to a kind of melting method of solid aluminum, especially a kind of method of dielectric heat aluminum melting.
Background technology
The processing of aluminium and its alloy first has to carry out it melting formation liquid, is reprocessed into various required
Shape, traditional aluminum melting method uses dry method aluminum melting technology, i.e. dry fluxing method.The exothermic heat source of dry fluxing method has external-heat and Nei Re
Formula, heat transfer type have radiation+convection current and conduction, and the type of furnace has burning (oil, gas or coal etc.) reverberatory furnace, resistance furnace and crucible furnace.Instead
Stove is penetrated with high-temperature flue gas caused by fuel combustion, heat is mainly heated into melting aluminum material in a manner of radiation+convection current, its shortcoming is
Blackness is small, and the absorption radiation thermal efficiency is low, and high-temperature flue gas residence time in burner hearth is of short duration, and convective heat exchange rate is low, and aluminaization is burnt
Damage is big, aluminium liquid air-breathing is more, and combustion air heat absorption is big, discharge amount of exhaust gas and takes away that heat is big, body of heater radiating is big, the thing such as energy consumption and aluminium
Material consumption is high, and pollutant discharge amount and labor intensity are big；Resistance furnace is generated heat with electric current by resistance wire, mainly with radiant heat transfer side
Formula melting aluminum material, shortcoming are that the slow production capacity of temperature rise is low, and fusing time length, heat loss is higher, are used for moisturizing and are used without making fusing；
The advantages of though crucible furnace has combustion product not contacted with furnace charge, and aluminium scaling loss is low, crucible capacity is small, and pot wall thermal resistance is big, poor heat transfer,
Short life；Within heat and conduction heat transfer mode aluminum melting have intermediate frequency and power frequency induction furnace, be to produce aluminium material in stove with electromagnetic induction
Raw secondary induced-current generates heat and melting aluminum, temperature rise are fast, and melting rate is high, and environmental protection is good, but melting stage power factor is low, magnetic field
Aluminium liquid is swelled, increases aluminium oxidation reaction from stirring is fiercer, the small short life of furnace capacity, difficulty meets that big industrial production will
Ask, especially when handling fritter bulk stock, energy consumption is high.It is conventional dry aluminum melting method above, aluminium material is exposed to before melting
In oxidisability furnace gas and air, although using flux covering protection, the scaling loss of aluminium still occurs and makes aluminium liquid air-breathing, causes degasification
The consumption such as agent and slagging agent is big, cost increase, wastes time and energy.
The content of the invention
A kind of method of dielectric heat aluminum melting is provided it is an object of the invention to overcome weak point of the prior art.
The method of this dielectric heat aluminum melting is the method melted by liquid resistance aluminium melting furnace to need aluminium material to be processed,
It is after liquid medium is placed in into liquid resistance aluminium melting furnace, then solid aluminum material to be processed will be needed to immerse in liquid medium,
Liquid medium reaches in aluminium material to heating in the state of air exclusion and takes the aluminium material of liquid when melting requires
Go out；Liquid medium is chloride or fluoride, and for its proportion less than aluminium material to be processed is needed, described aluminium material can be fine aluminium,
Can also be alloy aluminum, aluminium scrap.The present invention has the advantages that：The thermal efficiency is high, and exhaust emission is extremely low, and aluminium damages low and aluminium liquid
Not air-breathing, degasification operation need not be carried out, final product quality is high, consumption is low, cost is low, and labor intensity, raising security is greatly reduced.
Brief description of the drawings
Fig. 1 is the structural representation of liquid resistance aluminium melting furnace used in the method for dielectric heat aluminum melting.
Embodiment
The essentiality content of the present invention is described in further detail below in conjunction with specific embodiments.
In figure：1 --- outer --- --- bell 4 --- electrode-inserting holes 5 --- peephole of partition wall 3 of burner hearth 2
6 --- --- --- --- furnace lining anticorrosion layer 10 --- aluminium material 11 --- bases of furnace lining thermal insulation layer 9 of body of heater 8 of liquid medium 7
12 --- bottom girder 13 --- internal furnaces of seat
According to shown in Fig. 1, liquid resistance aluminium melting furnace used in the method for this dielectric heat aluminum melting mainly by burner hearth,
Bell, body of heater, furnace lining and pedestal composition.Body of heater 7 is located on pedestal 11 and bottom girder 12, has in body of heater 7 by furnace lining thermal insulation layer 8 and stove
Serve as a contrast the furnace lining that anticorrosion layer 9 forms.Bell 3 is located at the top of body of heater 7, and bell 3 is provided with electrode-inserting holes 4 and peephole 5, is easy to see
Examine the situation in measurement burner hearth.Space between body of heater 7 and bell 3 forms burner hearth, sets partition wall 2 in body of heater 7, and partition wall 2 is by burner hearth
Outer burner hearth 1 and internal furnace 13 two parts are separated into, mobile lid can be set on outer burner hearth 1, outer burner hearth 1 is easy to feed and discharged
Technological operation.Liquid medium 6 and aluminium material 10 to be processed is needed to be placed in burner hearth, liquid medium 6 is chloride or fluoride, liquid
For the proportion of state medium less than aluminium material to be processed is needed, described aluminium material 10 can be fine aluminium or alloy aluminum, aluminium scrap.
The method of this dielectric heat aluminum melting is to needing the method that aluminium material to be processed is melted, by liquid by aluminium melting furnace
After state medium 6 is placed in liquid resistance aluminium melting furnace, then solid aluminum material 10 to be processed will be needed to immerse in liquid medium 6, liquid
Medium 6 heats to aluminium material 10 in the state of air exclusion, reaches the aluminium of liquid in aluminium material 10 when melting requires
Material 10 takes out, and liquid medium 6 is chloride or fluoride, and the proportion of liquid medium 6, which is less than, needs aluminium material 10 to be processed, described
Aluminium material 10 can be fine aluminium or alloy aluminum, aluminium scrap.It is notable through practical effect.
