Description
Technical field
It is especially a kind of using fused cast refractories dust-removing powder as the sand of main material production the present invention relates to zirconia-corundum refractory brick coating
Mould special coating.
Background technique
In order to produce the fused cast refractories of higher quality, the sand mo(u)ld of fused cast refractories production at present has upgraded to resin sand sand mo(u)ld, sets
Rouge sand sand mo(u)ld can generate carbon dioxide gas and other gases under the condition of high temperature in casting process, these gases can make brick
Disadvantage more than face color pastiness, brick face stomata, in order to avoid these disadvantages, sand mo(u)ld inner core needs brushing high-temperature resistant coating, with painting
Layer separation gas endangers fused cast refractories surface, and the high-temperature coatings that fused cast refractories sand mo(u)ld uses are helped with zirconium matter material of main part, with other
Water based paint made of the non-auxiliary material of agent, coating cost is very big, 15000 yuan of zirconium quality high-temperature finished product coating market price per ton,
20 kilograms of mo(u)ld blacking dosage per ton, 300 yuan are converted into, this is a very big investment in fused cast refractories production process, occupies electricity
Molten brick sells a certain proportion of profit, therefore the reduction of fused cast refractories sand mo(u)ld coating cost is imperative.
The batch of fused cast refractories is the zircon sand of about 50% alumina powder and about 50%, and batch is added to electric furnace and carries out high temperature
The adding procedure of fusing can generate a large amount of dust, also known as dust-removing powder, and dust flies upward meeting to operative employee's noise health hazard, and
Dust is also more pure refractory material, and 1 ton of charging about generates 50 kilograms of dust, and 2 can be collected by producing 40 tons of fused cast refractories daily
Ton dust, due to aluminum oxide lighter in weight, aluminum oxide is most ingredient in dust, and dust includes following heavy
The raw material of amount: aluminum oxide 82.9%, silica 6.3%, zirconium dioxide 8.3%, sodium carbonate 1.5%.Dust-removing powder fire resisting
Degree can reach 1750 DEG C or more, meet high temperature resistant requirement as fused cast refractories coating.Annual 10000 tons of fused cast refractories of production generate
100 tons of dust.Dust-removing powder cannot be used for the raw material of fused cast refractories production, so dust-removing powder value is significantly less than the value of raw material,
This respect is a waste of material.All it is often heap not to be available, and cannot abandons, with the Far East fire resisting of applicant Zhengzhou
For Materials Co., Ltd, 3000 tons or more of dust-removing powder is overstock, when these dust-removing powders can only be as fused cast refractories production
Generation waste product material, can no longer be used to the raw materials for production of fused cast refractories, effective use of the dust-removing powder in fused cast refractories production
It is one project necessarily faced of enterprise.
Summary of the invention
For above situation, for the defect for overcoming the prior art, the purpose of the present invention is just to provide one kind and is removed with fused cast refractories
Dirt powder is the sand mo(u)ld special coating of main material production, can effectively solve to produce coating using fused cast refractories dust-removing powder, reduce cost
The problem of.
The technical solution that the present invention solves is: a kind of using fused cast refractories dust-removing powder as the dedicated painting of the sand mo(u)ld of main material production
Material, the raw material including following weight: water 5.3-6.7kg, dust-removing powder 10.75-14.75kg, xanthan gum 6-10g, polyethylene 38-
42g。
Preferably, the raw material including following weight: water 6kg, dust-removing powder 12.75kg, xanthan gum 8g, polyethylene 40g.
The dust-removing powder mainly includes the ingredient of following weight percent: aluminum oxide 82.9%, silica
6.3%, zirconium dioxide 8.3%, sodium carbonate 1.5%, surplus are impurity.
A kind of preparation method of sand mo(u)ld special coating, comprising the following steps:
(1) water of 4.5-5.5kg is poured into blender, and 250g dust-removing powder and 6-10g xanthan gum is added, and is stirred to mixed
It closes uniform；
(2) remaining dust-removing powder is added in mixture made from step (1), is stirred until homogeneous；
(3) 0.8-1.2kg water is poured into pot, and 38-42g polyethylene is added, be placed on stove fire, tanning is until poly- second
Alkene melts completely；
(4) polyethylene solution of step (3) is poured into while hot in mixture made from step (2), stir evenly to get.
Preferably, the Baume degrees of sand mo(u)ld special coating obtained is 79-82.
The formula of the invention is reasonable, greatly reduces the cost of manufacture of fused cast refractories sand mo(u)ld coating, and fused cast refractories per ton can save painting
Material expense is about 200 yuan, and 10,000 tons of fused cast refractories sand mo(u)lds can be 2,000,000 yuan of saving color expense, can not be reused in production process
A large amount of dust-removing powders can all recycle use, substantially increase the recycle value of dust-removing powder, dust-removing powder fusing point is lower than zirconium English
Powder, fusing point can reach about 1750 DEG C, can meet the high temperature resistant requirement of fused cast refractories sand mo(u)ld high-temperature resistant coating.Exactly dust-removing powder can be burnt
The temperature of knot, thus it is higher using the grade of fit that dust-removing powder is sand mo(u)ld coating, because forming one layer of hard shell after coating sintering, not only
Gaseous contamination brick face when resin being prevented to burn, the hard shell that coating is formed at high temperature can smoothly fall off naturally in brick output, brick
Face cleaning is more convenient, improves the efficiency of brick face cleaning, is the innovation on fused cast refractories sand mo(u)ld coating, there is good society and economy
Benefit.
