Key of refine aluminous furnace has furnace of reverberator, bowl and intermediate frequency electric induction furnace to wait, working temperature is 700-1000 ℃ normally. The infiltration that the damage key of system of line of this kind of burner is aluminous fluid and erode cause, its line system reachs fireproof Molaishi with clay brick, tall aluminous firebrick normally wall of bricky build by laying bricks or stones, also can make errant body with tall aluminium fireproof material, for example pouring makings, but plastic wait a moment and fire prevention material but plastic make, because applied standard is good, burner service life is longer.
Reverberator uses firebrick:
This furnace divides 2 kinds into movable type and bend to use formula, choose liquid gas or heavy oil to make normally expect like that. Aluminous smelt is used commonly fixed do not move reverberator to be not working layer to use heat preservation of qualitative heat insolation of fireproof fiber felt and clay wall of firebrick build by laying bricks or stones, the working middle-level of position of dissolve pool left and right sides has with wall of clay brick build by laying bricks or stones, also can make errant body with tall aluminium fireproof material, for example pouring makings, but plastic wait prefabricated components a moment piece remove condole or be in irrigate or be being begun on the spot is to use tall aluminium to make fire prevention material but plastic pound hit and become, provision of application of basis of middle-level of dissolve pool job is different, its material is different also, al2O3 water content is chosen below the state normally 75% tall aluminous firebrick of the left and right sides wall of build by laying bricks or stones, also can be 80% tall aluminium of the left and right sides to make errant body with Al2O3 water content fireproof material, for example pouring makings, but plastic irrigate etc overall job middle-level, when smelt tall bullion belongs to material aluminium, appropriate of middle-level of dissolve pool job uses high pure Mo Laishi brick, zirconium stone brick or wall of corundum brick build by laying bricks or stones. Put aluminous mouth, chamfer drifting aluminium and line system, so that resist,the infiltration of aluminous fluid is mixed corrode, choose normally large and medium-sized wall of carborundum brick build by laying bricks or stones.
Protect furnace of wet filling water and solution and aluminium alloy makings to solve room the photograph of used firebrick and reverberator is consistent. When choosing aluminous ingot or useless aluminium to make raw material, but from put makings mouth to be put into instantly smelt is begun inside furnace. If use,electroanalysis when aluminous fluid makes raw material. Most use siphon or vacuum bag to absorb aluminous fluid from the end end aluminous electrobath first, subsequently carry is gone to reverberator. From put makings mouth to fall into, put makings hind, the edge adds Wen Bian the insufflate inside Xiang Rongchi is hydric begin dehydrogenation place to bury, the line in siphon raises form of adventitious of light qualitative concrete with fireproof fiber normally fireproof material, for example pouring makings, but plastic make heat insulating materials etc, also can use firebrick of sticky earthy and adiabatic heat preservation wall of build by laying bricks or stones, its job middle-level chooses brick of high density clay or wall of corundum brick build by laying bricks or stones extensively. What vacuum wraps the thermal insulation board of li of line and siphon is same. Its job middle-level uses brick of high quality clay or tall aluminous firebrick wall of build by laying bricks or stones.
Bowl furnace uses firebrick:
Layer of job of this furnace blame pledges with clay firebrick of adiabatic heat preservation or bleach wall of bead brick build by laying bricks or stones, the form of adventitious of light qualitative concrete that also can be 1.0g/cm3 relative to density with cubage is fireproof material, for example pouring makings, but plastic irrigate etc or make prefabricated components piece wall of build by laying bricks or stones: The wall of tall aluminium firebrick build by laying bricks or stones that working middle-level perhaps is Al2O3 water content to exceed 55% with brick of high density clay, bowl furnace furnace life is 300-500 furnace normally second. Should add smelt of acerbity salt solution when aluminium piece. Because organic chemistry corrodes accentuation, its furnace life decreases then.
Intermediate frequency electric induction furnace uses firebrick:
This furnace lining uses clay brick or wall of firebrick build by laying bricks or stones of 3 class tall aluminium normally. Hearth adds tall aluminium to make errant body first occasionally fireproof material, for example pouring makings, but plastic irrigate etc rural basic level, subsequently again firebrick of tall aluminium of build by laying bricks or stones. Cubage of intermediate frequency electric induction furnace under 10t when, its line physical ability is the tall aluminous indeterminate form of 75% about with Al2O3 water content fireproof material, for example pouring makings, but plastic wait a moment or fire prevention material pounds dozen of makings to make, also can use form of fireproof qualitative adventitious fireproof material, for example pouring makings, but plastic wait a moment or dry-well type shakes makings. The line system of periphery of coil of electromagnetism of burner induction switch, choose form of fireproof qualitative adventitious normally fireproof material, for example pouring makings, but plastic etc overall irrigate or shake with dry-well type makings shake packing. What because raw material type is mixed,operate a level actually is different, burner operating period also is a difference. It is inside applied period, the line system of electromagnetism coil periphery fragile the position should begin 1-5 second small long.
Holding furnace uses firebrick:
Aluminous holding furnace is divided into silk of furnace of groovy body response, resistor to heat Chi Shilu and furnace of type of liquid gas chamber. Because equipment of this kind of machine operates temperature inferior, make line system with the raw material such as clay brick normally, also got higher operating period.
Furnace of groovy body response uses firebrick:
The line system construction of this furnace spreads 10mm to rely on furnace casing originally asbestine board or fireproof fiber felt, again firebrick of heat preservation of qualitative heat insolation of clay of wall of build by laying bricks or stones or the working middle-level that bleach bead brick to make heater of; of heat insulating materials and system of line of electromagnetism coil periphery choose material of sticky earthy fire prevention extensively to pound dozen of makings make, also can use sticky earthy and indeterminate form fireproof material, for example pouring makings, but plastic irrigate on the spot etc, large and medium-sized the working middle-level of furnace of groovy body response, the tall aluminous firebrick that also can exceed 55% with Al2O3 water content wall of build by laying bricks or stones.
