High-temperature refractory material and preparation method thereof
The invention relates to the technical field of refractory materials, in particular to a high-temperature refractory material and a preparation method thereof. The high-temperature refractory material comprises 50-70 parts by weight of fused white corundum particles, 10-20 parts by weight of Cr2O3, 10-20 parts by weight of alpha-Al2O3 powder, 1-4 parts by weight of TiO2 and 6-15 parts by weight of a binding agent. According to the prepared high-temperature refractory material, the aluminum-chromium refractory material prepared from the white corundum particles has the characteristics of low impurity content, excellent physical properties, good thermal shock resistance, good wear resistance, good normal-temperature fracture resistance coefficient and the like. The good normal-temperature fracture resistance coefficient facilitates manufacturing and processing of high-temperature refractory parts, the wear resistance coefficient is high, and the wear-resistant scratch effect is improved, so that the surface of the high-temperature material is convenient to clean after being bonded, and the surface of the outer layer cannot be damaged by scraping.
