Magnesium-ferrum-aluminum spinel kiln eye castable
The invention discloses magnesium-ferrum-aluminum spinel kiln eye castable. The magnesium-ferrum-aluminum spinel kiln eye castable is prepared from, by weight, 30-70 parts of electric melting magnesium-aluminum spinel, 25-50 parts of electric melting ferrum-aluminum spinel, 3-5 parts of zirconium carbonate, 3-5 parts of silicon carbide, 2-3 parts of silica powder, 2-8 parts of alumina micro powder and 0.1-1 part of sodium tripolyphosphate. The magnesium-aluminum spinel, the feerum-aluminum spinel and the like are added as high-grade raw materials, the product is high in resistance of corrosion of alkali gas such as potassium oxide and sodium oxide, a certain amount of cement clinker can be attached and hung to a kiln eye so as to protect the kiln eye, and the magnesium-ferrum-aluminum spinel kiln eye castable has the higher corrosion resistance and thermal shock resistance compared with originally-adopted aluminum-silicon refractory castable.
