Aluminum-magnesium-silicon pot edge castable and preparation method thereof
The invention relates to the field of steel-making steel ladle refractory materials, in particular to an aluminum-magnesium-silicon pot edge castable and a preparation method thereof and provides an aluminum-magnesium-silicon pot edge castable capable of solving the technical problems of difficult steel ladle pot edge slag treatment, cracks produced in the baking process, poor heat stability in the high-temperature using process and the like of steel ladle pot edges and a preparation method. The castable is prepared from, by weight, 20-25% of 3-8 mm waste sliding plate aggregate, 45-50% of 0-3 mm waste sliding plate aggregate, 5-8% of alumina powder, 9-12% of sintered magnesium powder, 3-7% of long aluminum A600 cement, 3-5% of silica dust, 5-7% of alpha aluminum oxide micro powder, 0.015%-0.02% of explosion-proof fiber and 0.2-0.3% of admixture sodium hexametaphoshpate. The aluminum-magnesium-silicon pot edge castable can effectively solve the problems of poor steel ladle pot edge application property, cracks, low strength, poor heat stability, difficult steel ladle pot edge slag treatment and the like and is especially suitable for preparation of aluminum-magnesium-silicon pots.
