Energy-saving corrosion-resistant magnesium-aluminum refractory material
The invention relates to an energy-saving corrosion-resistant magnesium-aluminum refractory material, and the material is mainly composed of the following components in parts by mass: 35-45 parts of high-purity magnesia, 30-40 parts of magnesium aluminate spinel, 2-4 parts of ultrafine calcium oxide micro powder, 0.1-0.4 part of graphene oxide powder, 3-7 parts of an auxiliary additive and 1-3 parts of a binding agent. The high-purity magnesia is formed by mixing magnesia with different granularities, the magnesium aluminate spinel is also formed by mixing magnesium aluminate spinel raw materials with different granularities, and the auxiliary additive can be one or a mixture of two of boron nitride and silicon dioxide. The refractory material has the advantages of being good in heat preservation effect, low in preparation process energy consumption and good in high-temperature performance.
