Description
Technical field
It is especially a kind of using fused cast refractories rubbed brick 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.
Fused cast refractories blank brick needs to finish, and so that fused cast refractories is reached final accurate dimensions, process of lapping is electric smelting
Brick is ground by diamond abrasive tool, in order to avoid high temperature that friction is formed when grinding, it is therefore desirable to which recirculated water is played in grinding
Cooling effect, recirculated water sedimentation basin can be entered with water flow by grinding the rubbed brick powder to get off, about 10 kilograms of the stock removal of brick per ton, be produced per year
10000 tons of fused cast refractories will generate 100 tons of rubbed brick powder.Due to rubbed brick powder metal impurities and other impurity (rubbed brick meal component itself
From brick ingredient without different, the iron content that only diamond abrasive tool during the grinding process is ground away is mingled in rubbed brick powder, is made
Its use value substantially reduces), it is consequently belonging to the waste product material of generation when fused cast refractories production, can no longer be used to fused cast refractories
Raw materials for production, thus this is the huge loss in a production process, effective use of the rubbed brick powder in fused cast refractories production again
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 ground with fused cast refractories
Brick powder is the sand mo(u)ld special coating of main material production, can effectively solve to produce coating using fused cast refractories rubbed brick powder, reduce cost
The problem of.
The technical solution that the present invention solves is: a kind of using fused cast refractories rubbed brick 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, rubbed brick powder 10.75-14.75kg, xanthan gum 6-10g, polyethylene 38-
42g。
Preferably, the raw material including following weight: water 6kg, rubbed brick powder 12.75kg, xanthan gum 8g, polyethylene 40g.
The rubbed brick powder mainly includes the ingredient of following weight percent: silicon 17.48%, aluminium 50.89%, zirconium 27.56%,
Iron 1.35%, sodium 1.46%, surplus are other ingredients (element and/impurity)；
The rubbed brick powder the preparation method comprises the following steps: rubbed brick powder is dried, then carry out making except iron program in ferromagnetic deironing device
Iron control is in weight percent less than 0.05% in rubbed brick powder.
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 rubbed brick powder and 6-10g xanthan gum is added, and is stirred to mixed
It closes uniform；
(2) remaining rubbed brick 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 rubbed brick powder can all recycle use, substantially increase the recycle value of rubbed brick powder, it is miscellaneous containing metal in rubbed brick powder
Its fusing point reduces when matter, and metal impurities will affect brick face quality, but contains through too strong magnetic except iron removes the iron in rubbed brick powder
Amount, the fusing point of rubbed brick powder can be improved, and fusing point can reach about 1690 DEG C to 1710 DEG C, can meet fused cast refractories sand mo(u)ld high-temperature resistant coating
High temperature resistant requirement.The exactly sintered temperature of rubbed brick powder, thus it is higher using the grade of fit that rubbed brick powder is sand mo(u)ld coating, because
To form one layer of hard shell after coating sintering, gaseous contamination brick face when not only resin being prevented to burn, what coating was formed at high temperature
Hard shell can smoothly fall off naturally in brick output, and the cleaning of brick face is more convenient, improves the efficiency of brick face cleaning, be that fused cast refractories sand mo(u)ld applies
Innovation on material has good social and economic benefit.
