As the ceaseless development of metallic smelt industry, aluminous goods has applied in each industries, the be called by a joint name of furnace of hot project kiln that aluminous fusion uses is frit aluminous furnace. Aluminous melting point is 660 ℃ , relatively inferior between numerous metal, but, aluminous active is very tall, have very strong osmosis ability, corrode of extremely easy dip is fireproof and pouring makings lining produces function to change, cause crackle, flake. Because this is in fireproof and pouring it is very important that the material of makings chooses to go up character.
Do not touch aluminium pouring if makings head is aggregate with tall aluminous aluminous grog, mix with tall aluminous aluminous grog and magnesia in all crocus expects for pink, make for bond with water glass, can use as bucket flourishing steel, ladle and liner of tapping chamfer collectivity. This series with high pure the low cement content that Shi Weiji of line of Molaishi, red cornerstone, silicon expects, up-to-date data that exceeds small pink union.
Because choose high pure material, exceed small pink union, this series data has stability of high volume density, high strenth, crackajack thermal shock, through increasing right amount “ ”(is like not damp agent high pure the) such as salt of oxidation chromium, compound barium, compound zinc salt, can drop substantially aluminium and alloy, slaggy the damp sex to fireproof data, progressed fireproof data is chemical to containing salinity, flux to wait the corrosion resistance of the aluminous fluid of composition, fight erode gender, do not touch aluminium and broken bits function, namely obstruct aluminium and alloy, slaggy enter fireproof data, outspread lining birthday is counted. Very apply to fused furnace, quiet place furnace, launder, aluminium to wrap liner.
Do not stick aluminium pouring expecting is a kind of new-style and complex fireproof material pouring makings, profession of the treatment that it is aluminium is special data, principal with Yu Rong the aluminous furnace boiler setting, hearth, box that remove gas, launder is mixed stream mouth, before box, it induced organic the character with inorganic bond, enter certain amount not dissolve at aluminium new-style and compound pouring makings, can direct to fireproof data and aluminous fluid space, because the harmful gas that breaks out in the process is refined in bead of aluminous fluid essence, played havoc with pouring the arrangement structure of makings, fight radiation for what this attends to be measured certainly data and counteract sexual data, intensity of agglomeration of stimulative low temperature, remove crackajack inhibition, progressed usefully of fireproof data use birthday number.
1, processing aluminium is industrial fireproof data the resonant problem at aluminous fluid, the up-to-date data that chooses proper motion research and development does not break out in process of aluminous fluid fusion aluminous ash, do not corrode, do not written guarantee tumour. Can huge drops the aluminous fluid loss in aluminous fusion process.
2, in pouring guess attend compound exceed fine pink to drop pouring the porosity of makings and stomatic aperture, adhere to and soak what avoid aluminous fluid. In aluminous fusion process, do not stick aluminium, do not hang broken bits, do not break out aluminous ash.
3, the echo that huge reduced aluminous fluid and fireproof data, the quality of ascensive aluminium alloy.
Do not touch aluminium pouring expecting is to be aimed at profession of domestic frit aluminium technically large frit aluminous furnace and the aluminium alloy fusion of the program is used pouring makings. This is pouring makings can be apparent ascensive frit aluminium alloy of furnace use birthday number, do not break out in aluminous fusion process aluminous ash, do not written guarantee corundum tumour, prevent metallic aluminous solution at fireproof endowment guessed elemental fit is resonant, avoid foreign matter to enter quality of aluminium alloy of the influence in aluminium alloy next. Drop the adherent rate of aluminous fluid, progress prevents ooze ability.
Do not touch makings is pouring makings in using a process, should notice the following 4 crucial link: Mix namely close, pouring, conserve, barbecue. Any link problem will bring about product function to drop or use failure among them.
One, mix close
1, equipment and tool: Forced shovel of mixer, pail, vibrating head, tool, barrow.
2, construction water consumption: Do not touch makings is pouring expect the quantity that add water should be controlled in 6.5-8% , need to use clean tap water.
3, construction site temperature needs to use under 10 Celsius warm up heat preservation measure square but construction. Can cause otherwise do not touch aluminium pouring makings construction difficulty or function drop, cause is invariable construction.
4, mix close: Will come loose first the packet inside makings and bag falls into mixer, press the quantity of the regulation that add water, accurate weigh out mix every time add up to place to need to use water, fall to already mixed in the drier that close, sufficient agitate, time not less than 1-3 minute, make have appropriate liquidity.
5, note: The place in construction process is like pail, mixer, shovel to wait with the tool must clean clean beforehand, do not allow to stick cement of dirty content, sundry, silicate waits. Construction uses water must clean tap water, mix every time add up to a quantity to should not be too big, answer to be decided according to mixer type name, careful water consumption answers in construction process too big.
2, pouring makings
1, pouring makings working face asks must clean (the mark that do not have salt, anhydrous mud mark) dry. Maintenance needs will former remains will pouring makings is cleared and clean.
2, pouring time: Mix newly those who had closed is pouring makings should undertake quickly pouring, finish inside 20 minutes commonly.
3, pouring: Will mix those who had closed is pouring expect, use vibrating head in time (60 vibrating head) shake, have bleb eduction face.
4, note: Pouring what fluidity already lost to already condensed namely in the process is pouring makings cannot add water agitate to use. Pouring good pouring makings should maintain natural appearance. Unfavorable wipe light with the tool, more cannot the surface scatters cement fine pink to wipe light. After construction ends, namely construction inside 24 hours, especially pouring expect before sclerosis, forbidden beat or shake, can produce crackle otherwise, and even destroy completely.
3, conserve
Pouring makings it is after sclerosis, must cover with polyethylene plastic film instantly construction system appearance, wet careless bag is built above, evaporate in order to prevent moisture, make cement activation. Sclerosis hind is forbidden beat, shake, the basis is sclerotic the situation is general a day can drawing of patterns. Conserve of add of succeed of drawing of patterns, plastic film and careless bag are uncovered after 3 days, make sclerotic system natural in air dry 3 to 5 days can barbecue.
4, roast
Roast it is pouring expect use the last crucial segment, because this are pouring makings is more compact, because this is in roast when prohibit warming up absolutely fast. Can cause otherwise pouring makings occurrence crackle, perhaps cause burst apart accident, the influence is pouring the use effect of makings.
