Compound refractory material and preparation method thereof
The invention relates to a compound refractory material and a preparation method thereof. The compound refractory material is prepared by using magnesium aluminate spinel with different grain diameters as a main raw material and adding auxiliary additives, nano-chromium oxide, a binding agent and nano-alumina. According to the compound refractory material, the strength and thermal shock resistance can be improved due to the uniform tissue structure; and micro-pores can be filled with the nano-zinc oxide due to the fine granularity, so that the porosity of the material can be reduced, and the volume density can be improved. The compound refractory material has the advantages of high refractoriness, excellent corrosion resistance, good thermal shock resistance and wide sintering temperature range.
