Molten aluminum erosion resistant refractory material and preparation method thereof

DONG HONGQIN / FAN XIAOLE / LI JIANTAO

The invention relates to a refractory material resistant to molten aluminum erosion and a preparation method thereof. The refractory material can be selected from the following components in percentage by mass: 30%-95% of an AMC complex phase material, 0%-5% of metal aluminum powder or magnesium aluminum alloy, 0%-8% of aluminum oxide micro powder and 0%-4% of aluminum sol. According to the refractory material, the advantages of high chemical purity, trace silicon dioxide content and non-wetting on molten aluminum of the AMC complex phase material are fully utilized, so that the refractory material has the advantages of high temperature resistance, good corrosion resistance and higher thermal shock stability; on the basis, part of metal or metal alloy is added, so that the technical effects of oxidation weight increment, air hole filling and pore diameter reduction in the firing process are realized, and the harmonious and unified use effects of slag corrosion resistance, high thermal shock stability and permeability resistance of the refractory material are further realized; and the refractory material can be fired in cooperation with other fired products, the firing temperature does not need to be independently adjusted, and the refractory material belongs to a production-friendly product.
