Abstract
The invention discloses a preparation method of corundum honeycomb ceramic with slag resistance. The method comprises the following steps: following raw materials of bauxite, kaolin, soapstone and feldspar are added in a ball mill according to proportion and are mulled into mixed material, then the mixed material is added in a kneader, then a proper amount of water and adhesive agent are added in the kneader, then the triteness, the pug milling, the drying, the cutting and the high-temperature sintering are performed after kneading to obtain a honeycomb ceramic, aluminium-chromium phosphate solution is coated on the surface of the inner wall of a corundum honeycomb ceramic hole, then the corundum honeycomb ceramic is dried and then baked at 1380 DEG C, and the aluminium-chromium phosphate is dehydrated, cured and stuck on the surface of the inner wall of the corundum honeycomb ceramic hole. The prepared honeycomb ceramic not only has high specific surface area, high porosity and good heat storage property; since an aluminium-chromium phosphate compound protective layer is coated on the surface of the inner wall of the honeycomb ceramic hole, the protective layer does not react with the ferrous oxide in the iron scale and is not stuck with the liquid-phase residue formed by the iron scale at the high temperature to ensure that the honeycomb ceramic hole is not blocked, the slag resistance of the corundum honeycomb ceramic is enhanced and the service life of the corundum honeycomb ceramic is prolonged.
Description
Technical field
The present invention relates to a kind of corundum honeycomb ceramic preparation method with slag resistance.
Background technology
As everyone knows, in various industrial furnace heat accumulating type industrial heating furnaces such as iron and steel, petrochemical industry, ceramic honey comb is an ideal material of making heat accumulating type industrial heating furnace heat storage, honeycomb ceramic heat accumulator is the key part in the heat accumulating type industrial heating furnace, it can improve combustion efficacy, save energy can reduce noxious gas emission again, reduces environmental pollution.Yet honeycomb ceramic heat accumulator stands flue gas repeatedly and air washes away, and can cause the temperature of ceramic honeycomb heat storage frequent variations to occur, thereby its material is had higher requirement.The ceramic honey comb material heat impact strength that uses in the engineering is often bad, occurs disrepair phenomenon easily.And corundum honeycomb ceramic is so that its thermal shock resistance is good, specific heat is big, density is big, the intensity advantages of higher is favored.But because the slag resistance of corundum honeycomb ceramic is not very good again, when steel surface oxidation in the process furnace generates iron scale, iron scale can be inhaled in the heat storage burner with hot blast, and at high temperature form the liquid phase slag, the liquid phase slag sticks in the ceramic honey comb hole easily, cause the ceramic honey comb hole plug, cause the damage of honeycomb ceramic heat accumulator, shortened the work-ing life of honeycomb ceramic heat accumulator.
Summary of the invention
At the anti-slag ability of corundum honeycomb ceramic in the above-mentioned existing engineering application, the problem that work-ing life is short, it is big to the invention provides a kind of specific surface area, the porosity height, heat storage performance is strong, and has the preparation method of the corundum honeycomb ceramic of good slag resistance.
Preparation method with corundum honeycomb ceramic of slag resistance, its method steps is:
(1) earlier bauxitic clay, kaolin, talcum and feldspar are added ball mill in proportion, mixed grind becomes compound,
(2) compound is added in the kneader, in kneader, adds an amount of water and caking agent again, carry out old, refining mud, oven dry, cutting and high temperature sintering after the kneading and make corundum honeycomb ceramic,
(3) the aluminum phosphate chromium solution is coated on the inner wall surface of corundum honeycomb ceramic hole, then corundum honeycomb ceramic is dried, again with corundum honeycomb ceramic 1380 ℃ down insulation fire, make aluminum phosphate chromium dehydrating and curing and be tightly adhered on the inner wall surface of corundum honeycomb ceramic hole.
Described corundum honeycomb ceramic profile is square, rectangular parallelepiped or right cylinder, is formed with size in corundum honeycomb ceramic inside evenly and be the hole of parallel or staggered arrangement, and described hole shape can be trilateral, square, hexagon, circle or oval.
Corundum honeycomb ceramic of the present invention inside has tight ordered arrangement, wall is thin and hole of uniform size; its corundum honeycomb ceramic is specific surface area and porosity height not only; heat storage performance is good; and owing on the inner wall surface of corundum honeycomb ceramic hole, be coated with one deck aluminum phosphate chromium cpd protective layer; the iron protoxide reaction of this protective layer in can iron scale; protective layer can not bondd liquid phase slag that iron scale at high temperature forms; guarantee that the ceramic honey comb hole can not stop up; improve the anti-slag ability of corundum honeycomb ceramic, prolonged the work-ing life of corundum honeycomb ceramic.
