Description

The refractory ceramics glaze and preparation method thereof of large size casting sintering furnace door brick
Technical field
The present invention relates to a kind of refractory material, especially a kind of the refractory ceramics glaze and its system of large-scale casting sintering furnace door brick Preparation Method.
Background technique
Coke oven provides important coke and coal gas for smelting industry, is indispensable ancillary equipment, fire door cordierite lining Brick thermal expansion coefficient is smaller, and intensity is relatively high, and use has adapted to coke oven door without decomposing and converting at 1300 DEG C Requirement.But since its porosity is too high, harmful substance caused by coking is easy to brick body internal penetration, causing The corrosion physical property of lining brick is learned, while tar and carbon ash are readily adsorbed in lining brick surface and form carbon formation layer, carbon formation layer Removal accelerate the damage of brick body, reduce the service life, increase workload.
Summary 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 service life.
Technical solution: the invention adopts the following technical scheme: a kind of refractory ceramics glaze of large-scale casting sintering furnace door brick, is pressed It include 5~8 parts of feldspars, 40~45 parts of spodumene powder, 20~30 parts of fused quartz powders, 7~13 parts of α-aluminium 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 5:3. with the quality summation of zinc oxide and the mass ratio of water
It according to parts by weight include 6 parts of feldspars, 43 parts of spodumene powder, 25 parts of fused quartz powders, 10 parts of α-oxygen as optimization 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 greater than 99%.
A kind of preparation method of the refractory ceramics glaze of large-scale casting sintering furnace door brick, comprising the following steps:
1) ingredient: according to required yield, weight needed for calculating each raw material is required accurately to weigh each original according to formula rate Material;
2) ball milling: the raw material prepared is added in ball grinding cylinder, and 37% water is added, and for 24 hours, slurry is made in booting ball milling;
3) glazing: by the good slurry of ball milling using spray gun even application on the working face of furnace door brick, with a thickness of 1.2- 1.5mm;
4) dry: to dry 12h in the environment of the furnace door brick sprayed is placed in 80-100 DEG C;
5) it is burnt into: the brick after drying being put into kiln, is burnt under oxidizing atmosphere, 1300~1320 DEG C of firing temperature;
6) finished product is checked and accepted: after product kiln discharge, being carried out an acceptance inspection by quality inspection personnel to product.
As optimization, raw material includes feldspar, spodumene powder, fused quartz powder, Alpha-alumina micro mist, life in the step 1) Talcum powder, zirconium dioxide and zinc oxide.
Principle: glaze is widely used as functional material, and main characteristic is its high compactness and very strong impermeabilisation And resistance to corrosion, one layer of high temperature glaze is coated on the surface of cordierite, can prevent it from forming carbon formation layer at work, cause simultaneously The high glaze layer of close property can reduce erosion of the pernicious gas to brick body.So in order to improve the service life of cordierite furnace door brick, Production cost is reduced, is increased economic efficiency, it is Li that we, which study the system that is prepared for,2O-MgO-Al2O3-SiO2The large-scale casting of system It is sintered the refractory ceramics glaze of furnace door brick.
The utility model has the advantages that the present invention is compared with prior art:
1) the refractory ceramics glaze for the large-scale casting sintering furnace door brick that the present invention is developed has good melting behaviour, heat swollen Swollen coefficient is smaller, using the high feature of temperature, the expansion coefficient similar of thermal expansion coefficient and cordierite, attachment that can be stable On the surface of cordierite furnace door brick, it will not cracking, peel off in the long-term use.Due to the crystallization of cordierite and spodumene Temperature is all at 1300 DEG C or more, so the glaze is suitble to be burnt at 1350 DEG C, so 1200 DEG C of coke oven at a temperature of work When it is more stable.This just improves the service life of cordierite furnace door brick, reduces maintenance number, increases economic efficiency.
2) thermal expansion coefficient is small, and main group of the glaze layer becomes glass state material and a small amount of zircon, quartz and β-lithium brightness Stone solid solution crystals, the ZrO in raw material2With the precipitation of 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, and β-spodumene solid solution is largely precipitated Body, so that the coefficient of expansion of glaze reduces.
3) strong ability to resist penetration of glaze, material form glassy state when firing, have certain mobility, with violet blueness Stone furnace door brick surface is tightly combined, and is flowed so that the hole etc. of itself is filled up, so that it has densification well Property, air permeability sharp fall enter in furnace door brick body and make so that glaze can resist carbon and harmful substance in the course of work At destruction.
