Abstract
The invention relates to a coating against binding slags for aluminum, which is mixed by a main material and an auxiliary material, wherein, the main material is composed of aluminum slag, silicon ash and a carbon-containing material, weight of aluminum slag accounts for 30-40% of total weight of the main material, weight of silicon ash accounts for 50-60% of total weight of the main material, the auxiliary material comprises a high temperature bonding agent with 1-8% of weight of the main material, cellulose with 1-6% of weight of the main material, an antifoaming agent with 0.1-1% of weight of the main material and bone meal with 1-5% of weight of the main material. In the invention, the main material enables hardening at high temperature environment under assist of the auxiliary material such as high temperature bonding agent and cellulose, so that aluminum liquid and an inner wall of the furnace can be separated by a protective layer, a filtrate slag is bound on the protective layer, erosion of the aluminum liquid and damage of aluminum liquid slag on the inner wall of the furnace to the furnace wall can be effectively avoided; simultaneously, the carbon-containing material is oxidized under high temperature, so that the protective layer formed by a cleaning material and the inner wall of the furnace enable infirm binding, and the aluminum slag on the inner wall can be easily removed.
Description
Technical field
The present invention relates to the aluminium liquid splendid attire stove that aluminum casting, aluminium remelting and casting field are used, a kind of aluminium stove coating against binding slags specifically.
Background technology
Need to be by reprocessing after aluminium fusing or the field producing in aluminum casting, aluminium remelting and casting, aluminium deep processing etc., in these fields, after aluminium is melted, stove inwall can continuous slagging scorification, causing aluminium to be mixed into furnace volume constantly diminishes, the stove of 40 tons can only hold 10 tons of aluminium or still less, can cause every stove to enter aluminium amount few, has a strong impact on every furnace output.Must carry out brute force cleaning with multiple personnel or cleaning equipment just can clean out, sometimes equipment stove inner wall cleaning has been got well, inwall has also been hindered, affect work-ing life (1 year life-span of 2 years can not be used), need again build stove, nearly 500,000 yuan of expenses of every block are difficult problems urgently to be resolved hurrily in aluminum casting industry.
Summary of the invention
The series of problems causing with the furnace wall slagging scorification of stove for solving aluminium, the invention provides a kind of aluminium stove coating against binding slags, before producing each time, brush clean material of the present invention at aluminium with painting on stove inwall, the slagging scorification of aluminium liquid can be attached on the clean bed of material, thereby remove from furnace wall easily.
The present invention solves the problems of the technologies described above the technical scheme of employing to be: a kind of aluminium stove coating against binding slags, mixed by major ingredient and auxiliary material, wherein, major ingredient is made up of aluminium slag, silicon ash and carbonaceous material, and the weight of aluminium slag accounts for the 30-40% of major ingredient gross weight, the weight of silicon ash accounts for the 50-60% of major ingredient gross weight; Described auxiliary material comprises the high temperature adhesive of major ingredient weight 1-8%, Mierocrystalline cellulose, the defoamer of major ingredient weight 0.1-1% and the bone meal of major ingredient weight 1-5% of major ingredient weight 1-6%.
In described auxiliary material, also contain the sanitas of major ingredient weight 0.1-1%.
In described auxiliary material, also contain the cryolite powder of major ingredient weight 1-3%.
Described carbonaceous material is Graphite Powder 99.
The preparation method of above-mentioned coating against binding slags is: first weigh as requested the each composition in each composition and auxiliary material in major ingredient and then mix, be ground to again fineness and be no more than 100 orders, in use, add wherein a certain amount of water and stir after be painted on aluminium with on stove inwall, after brushing 2-3 time, dry in the cool, and then repeat above-mentioned brushing, dry operation and can complete for one to twice, then this aluminium can be for the production of with stove.
In the present invention, silicon oxide in aluminum oxide in aluminium slag and silicon ash forms the structure of similar sial spinel under hot conditions, and auxiliary material is its bonding rear formation protective layer, Mierocrystalline cellulose at high temperature dewaters after coking and is filled in wherein to prevent that corrosive gas from contacting effects such as causing corrosion or erosion with inboard wall of furnace body; Meanwhile, aluminium slag can not pollute aluminium liquid yet, and, thereby the new aluminium slag forming is more easily attached on coating and is removed.
In the present invention, by adding cryolite powder and carbonaceous material, thereby make the aluminium liquid can be crosslinked with the protective layer that clean material forms, make the slagging scorification of aluminium slag energy on protective layer and do not contact with inwall; Meanwhile, due to carbonaceous material oxidation at high temperature, thereby it is not firm bonding that protective layer and contacting of inwall are become, convenient by the slagging scorification removing on furnace wall.
The bone meal using in the present invention is pulverized and is formed for animal skeleton, it at high temperature plays auxiliary material and the better effect of merging of major ingredient of making, make in structure that the materials such as the Mierocrystalline cellulose in auxiliary material can uniformly penetrating at high temperature form in major ingredient, simultaneously, give dope layer certain high-temperature shrinkage ability, prevent that it is dry and cracked.
Beneficial effect: in the present invention, the major ingredients such as aluminium slag, silicon ash are under the auxiliary material such as high temperature adhesive and Mierocrystalline cellulose auxiliary, can in hot environment, harden, thereby forming protective layer separates aluminium liquid and inboard wall of furnace body, and make filtrate slagging scorification on protective layer, effectively prevent the damage to furnace wall after the erosion of aluminium liquid to body of heater and aluminium liquid slagging scorification are on inboard wall of furnace body; Meanwhile, carbonaceous material oxidation at high temperature, becomes protective layer that clean material forms and inboard wall of furnace body illusive bonding, thus be easy to by its with and on the aluminium slag that adheres to dispose easily.
