Abstract
An aluminum melting furnace cast refractory material is prepared through using the following raw materials, by weight, 50-60 parts of bauxite, 30-35 parts of 1-50mum brown fused alumina, 15-20 parts of a silicon-based floating bead, 10-15 parts of alumina, 20-25 parts of white mud, 20-25 parts of quartz sand, 10-15 parts of mullite, 10-15 parts of 30-80mum silicon carbide, 5-10 parts of sodium tripolyphosphate, 15-20 parts of andalusite, 1-2 parts of zirconia, 2-3 parts of titanium oxide, 15-20 parts of potash feldspar and 10-15 parts of vermiculite. In the invention, bauxite is used as a primary material, the particle sizes of the raw materials are preset, and parts of the raw materials are molten, and then are cooled and crushed, so the combination force among the raw materials is enhanced, the thermo stability of the refractory cast material is improved, the thermal shock resistance stability of the cast material is good, a reaction of the cast material and the aluminum element is difficult, the penetration of molten aluminum is effectively prevented, and the service life of a furnace is prolonged. The aluminum melting furnace can be used for 2-3 years, and the washing of the inner wall of the furnace is less.
Description
Technical field
The present invention relates to a kind of aluminum smelting technology technology, specifically build the mould material used in molten aluminium stove process, it can significantly improve the work-ing life of molten aluminium stove.
Background technology
At present, building the mould material used in molten aluminium stove process, there is heat-resistant knocking stability difference, easily be washed, corrode, easily occur breakage after using for some time, occur aluminising, need to repair, and furnace wall is easy and aluminium element generation chemical reaction, reduces the quality of product.
Summary of the invention
The object of this invention is to provide a kind of molten aluminium stove pouring fireproof material and preparation method thereof, improve the thermostability of refractory casting material, mould material not easily occurs that burn into is damaged, long service life.
Technical scheme of the present invention is as follows:
A kind of molten aluminium stove pouring fireproof material, is characterized in that being made up of the raw material of following weight part: aluminium vanadine 50-60,1-50 μm of Brown Alundum 30-35, siliceous drift pearl 15-20, aluminum oxide 10-15, white clay 20-25, quartz sand 20-25, mullite 10-15,30-80 μm silicon carbide 10-15, tripoly phosphate sodium STPP 5-10, andaluzite 15-20, zirconium white 1-2, titanium oxide 2-3, potassium felspar sand 15-20, vermiculite 10-15.
The preparation method of described molten aluminium stove pouring fireproof material, is characterized in that comprising the following steps:
(1), by aluminium vanadine, andaluzite, potassium felspar sand, vermiculite be heated to 2000-2500 DEG C of high temperature melt, stir after 30-40 minute, pour Quench in cold water, then be ground into the fine powder of 1-30 μm;
(2), by quartz sand, mullite, aluminum oxide, white clay be heated to 1800-2000 DEG C of high temperature melt, stir after 30-40 minute, pour Quench in cold water, then be ground into the fine powder of 80-120 μm;
(3), the fine powder that step (1), (2) obtain is mixed with other leftover materials after, temper and get final product.
Advantage of the present invention: with aluminium vanadine for major ingredient, by the setting of the particle diameter of raw material, after part material melting, cooling crush again, enhances the bonding force between raw material, improves the thermostability of refractory casting material, the heat-resistant knocking stability of this mould material is good, be not easy to react with aluminium element, effectively can stop the infiltration of molten aluminium, extend the work-ing life of stove.Molten aluminium stove can use 2-3, and stove inwall washes away few.
