Description
Technical field
The present invention relates to a kind of refractory material, the refractory ceramics glaze and its system of particularly a kind of large-scale cast sintering furnace door brick
Preparation Method.
Background technology
Coke oven provides important coke and coal gas for smelting industry, is indispensable auxiliary equipment, fire door cordierite lining
Brick thermal coefficient of expansion is smaller, and intensity is relatively high, using without decomposing and converting at 1300 DEG C, has adapted to coke oven door
Use requirement.But it is due to that its porosity is too high, the harmful substance produced by coking is easily to brick body internal penetration, causing
The corrosion physical property of lining brick is learned, while tar is readily adsorbed in lining brick surface with carbon ash forms carbon formation layer, carbon formation layer
Removal accelerate the damage of brick body, reduce the life-span, increase workload.
The content of the invention
Goal of the invention:Too high it is an object of the invention to solve the existing furnace door brick porosity, harmful substance is easily permeated, drop
The problem of low lining brick physical property, reduction life-span.
Technical scheme:The present invention uses following technical scheme:A kind of large-scale cast sinters the refractory ceramics glaze of furnace door brick, presses
Include 5~8 parts of feldspars, 40~45 parts of spodumene powder, 20~30 parts of fused quartz powders, 7~13 parts of α-aluminum oxide according to parts by weight
Micro mist, 5~10 parts of raw talcum powder, 2~5 parts of zirconium dioxides, 2~5 parts of zinc oxide and 48~70 parts of water.
As optimization, the feldspar, spodumene powder, fused quartz powder, Alpha-alumina micro mist, raw talcum powder, zirconium dioxide
It is 5 with the quality summation of zinc oxide and the mass ratio of water:3.
As optimization, include 6 parts of feldspars, 43 parts of spodumene powder, 25 parts of fused quartz powders, 10 parts of α-oxygen according to parts by weight
Change aluminium micro mist, 8 parts of raw talcum powder, 4 parts of zirconium dioxides, 4 parts of zinc oxide and 59 parts of water.
As optimization, the dioxide-containing silica of the fused quartz powder is more than 99%.
A kind of preparation method of the refractory ceramics glaze of large-scale cast sintering furnace door brick, comprises the following steps:
1) dispensing:According to required yield, require that weight needed for calculating each raw material accurately weighs each original according to formula rate
Material;
2) ball milling:The raw material prepared is added in ball grinding cylinder, 37% water is added, start shooting ball milling 24h, and slurry is made;
3) glazing:Use spray gun even application on the working face of furnace door brick the good slurry of ball milling, thickness is 1.2-
1.5mm;
4) dry:12h is dried in the environment of the furnace door brick sprayed is placed in into 80-100 DEG C;
5) burn till:Dried brick is put into kiln, burnt till under oxidizing atmosphere, 1300~1320 DEG C of firing temperature;
6) finished product is checked and accepted:After product kiln discharge, product is carried out an acceptance inspection by quality inspection personnel.
As optimization, the step 1) in raw material include feldspar, spodumene powder, fused quartz powder, Alpha-alumina micro mist, life
Talcum powder, zirconium dioxide and zinc oxide.
Principle:Glaze is widely used as functional material, and its main characteristic is its high compactness and very strong impermeabilisation
And resistance to corrosion, a floor height temperature glaze is coated on the surface of cordierite, can prevent it from forming carbon formation layer at work, is caused simultaneously
The high glaze layer of close property can reduce erosion of the pernicious gas to brick body.So the service life in order to improve cordierite furnace door brick,
Production cost is reduced, is increased economic efficiency, we study the system that is prepared for for Li2O-MgO-Al2O3-SiO2The large-scale cast of system
Sinter the refractory ceramics glaze of furnace door brick.
Beneficial effect:The present invention is compared with prior art:
1) the refractory ceramics glaze for the large-scale cast sintering furnace door brick that the present invention is developed has good melting behaviour, heat swollen
The expansion coefficient similar of the characteristics of swollen coefficient is smaller, temperature in use is high, its thermal coefficient of expansion and cordierite, the attachment that can stablize
On the surface of cordierite furnace door brick, it will not ftracture, peel off during long-term use.Due to cordierite and the crystallization of spodumene
Temperature is all more than 1300 DEG C, so the glaze is adapted to burn till at 1350 DEG C, so being worked at a temperature of 1200 DEG C of coke oven
When it is more stable.This just improves the service life of cordierite furnace door brick, and reduction maintenance number of times is increased economic efficiency.
2) thermal coefficient of expansion is small, and the main composition of the glaze layer is glass state material and a small amount of zircon, quartz and β-lithium brightness
ZrO in stone solid solution crystals, raw material2Separated out with zircon crystal, and vitreous silica is partially converted into the quartz of crystalline state, and lithium
Pyroxene generates β-spodumene solid solution, under accurate controlled temperature conditions, extends soaking time, largely separates out β-spodumene solid solution
Body so that the coefficient of expansion reduction of glaze.
3) strong ability to resist penetration of glaze, material forms glassy state when burning till, blue or green with violet with certain mobility
Stone furnace door brick surface is tightly combined, and flowing make it that hole of itself etc. is filled up so that it has fine and close well
Property, air permeability significantly declines, and enters and is made in furnace door brick body so that glaze can resist carbon and harmful substance in the course of work
Into destruction.
