Description
Technical field
The present invention relates to a kind of refractory material, particularly a kind of light-weight mullite cordierite glazed tile and preparation method thereof.
Background technology
Coke oven provides important coke and coal gas for smelting industry, is indispensable auxiliary equipment, and cordierite fire door serves as a contrast
The thermal coefficient of expansion of brick is smaller, and intensity is relatively high, using without decomposing and converting at 1300 DEG C, has adapted to coke oven door
Requirement.Because the fire door lining brick of iron and steel enterprise and the coking coke oven of coking industry for a long time by thermal shock, chemical attack and
Mechanical shock, cause its service life shorter, thus the fire door lining brick of high quality should possess higher thermal shock resistance and resist
Infiltration, anticorrosive and anti-carbon, while the furnace door brick glazed tile that should have energy-conservation and environmental protection efficacy concurrently arises at the historic moment.
In response to national environmental protection power conservation requirement so that the cost of coking industry passively improves, and reduces its production
Benefit, and the large-scale appearance for pouring furnace door brick of Idiotype in recent years so that this problem of coking industry has obtained changing well
It is kind.Because the product has energy-conserving and environment-protective, thermal shock resistance height, impermeabilisation, anticorrosive, anti-carbon performance by force and installs maintenance side
Just, liking for users has been obtained, there is the trend popularized on a large scale.
The content of the invention
Goal of the invention：It is big it is an object of the invention to solve existing furnace door brick weight, thermal conductivity factor height and production cost
The problem of high.
Technical scheme：The present invention uses following technical scheme：A kind of light-weight mullite cordierite glazed tile, in parts by weight
Including 10~20 parts of light-weight mullites, 17~35 parts of flint clays, 5~13 parts of vitreous silicas, 14~25 parts of cordierites, 3~13 parts
Alpha-alumina, 8~15 parts of alumina and 6~13 water.
Further, the matter of the light-weight mullite, flint clay, vitreous silica, part cordierite, alpha-alumina and alumina
The mass ratio for measuring summation and water is 9:1.
Further, in parts by weight including 15 parts of light-weight mullites, 26 parts of flint clays, 9 parts of vitreous silicas, 19 parts of violet green grass or young crops
Stone, 8 parts of alpha-aluminas, 11 parts of alumina and 9 water.
Further, the dioxide-containing silica of the fused quartz powder is more than 99%.
Further, the light-weight mullite particle diameter is 1~5mm, and alumina content is more than or equal in light-weight mullite
70%, iron content is less than or equal to 1.03%.
Further, alumina content is more than or equal to 79% in the alumina, and iron oxide content is less than or equal to 1.0%.
A kind of preparation method of light-weight mullite cordierite glazed tile, comprises the following steps：
1) dispensing：Require that weight needed for each raw material of calculating accurately weighs each raw material according to formula rate；
2) pour into a mould：First prepare various cast utensils before cast, mould is fixed in vaccum-pumping equipment；By formula rate
It is required that the various raw materials added in addition to composition water carry out dry-mixed 3-5min, add additive and water inventory 85% is stirred
Mix, start wet mixing 2-5min or so, be shaped to require with pug flowing sexual satisfaction, depending on its dry and wet situation, add remaining water, continue
1-3min, discharging are mixed again；Start vacuum equipment to be vacuumized, when vacuum reaches 0~0.6Torr, open vacuum equipment
Charging aperture, the pug mixed is added to the charging aperture of vacuum equipment, bumper power supply is opened, while is vibrated with shock club,
Lasting charging, pay attention to observing material position in mould, until expecting position, hence it is evident that be vented mistake, surface bleeding is preferably；
3) conserve and be stripped：Base substrate after the shaping that step 2) obtains takes off in natural environment after curing in the mold 5-20 hours
Mould；Standard curing 3-7 days is carried out after the demoulding；
4) inspection of semifinished product：Quality inspection personnel is pressed to the semi-finished product after the demoulding《Pour into a mould fire door lining brick semi-finished product acceptance criteria》Enter
Performing check；
5) biscuiting：The biscuiting 24h-72h under the conditions of 500-1000 DEG C；
6) glazing：The good slurry of ball milling is used into spray gun even application on the working face of furnace door brick, thickness about 1.2-
1.5mm；
7) dry：12h is dried in the environment of the furnace door brick sprayed is placed in into 80-100 DEG C；
8) burn till：The dried brick of step 7) is put into kiln, burnt till under oxidizing atmosphere, firing temperature 1300~1320
℃；
9) finished product is checked and accepted：After product kiln discharge, product is carried out an acceptance inspection by quality inspection personnel.
Further, raw material includes light-weight mullite, flint clay, vitreous silica, part cordierite, α-oxygen in the step 1)
Change aluminium powder and alumina.
Further, vaccum-pumping equipment is closed after the step 2) casting complete, mould is removed, while fragment of brick is poured
Note face carries out floating.
Further, in the step 6), the material of glazing balls milled will be stone, spodumene powder, fused quartz powder, α-
Alumina powder, raw talcum powder, zirconium dioxide and zinc oxide.
Beneficial effect：The present invention is compared with prior art：
1) the product thermal conductivity factor is small, light-weight mullite material is added in raw material, the porosity of light-weight mullite is higher, makes material
The internal sealed porosity of material increases, and apparent porosity is greatly improved, and internally dry air content is higher, and its thermal conductivity coefficient is got over
It is low, therefore reduce the thermal conductivity factor of the product.It is additionally, since and uses light-weight mullite, makes the overall weight of the product reduce,
Raw material resources consumption is reduced, improves economic benefit.
2) strong ability to resist penetration of the product, the product in process of production, can be in one layer of high-temperature glaze of surface spraying, glaze
Material forms glassy state when burning till, and has certain mobility, is tightly combined with brick body surface, and flows and cause itself
Hole etc. filled up so that it has good compactness, and air permeability significantly declines, so that glaze can resist
Carbon and harmful substance, which enter in furnace door brick body, in the course of work damages, and improves impermeabilisation and corrosion resistance.
3) flint clay mainly plays support brick strength in the feed using 5-10mm grain graininess as aggregate
Effect, similar to the stone in concrete floor, but it is again higher in the presence of its intensity referring now to the stone of prior art, quality is lighter
Advantage, and can be good at mixing with light-weight mullite, play synergy.
