High-strength refractory material as well as preparation method and application thereof
The invention relates to a high-strength refractory material and a preparation method and application thereof, and belongs to the technical field of refractory materials, the refractory material comprises the following raw materials: fused corundum, high bauxite clinker, metal silicon powder, an anti-cracking agent, titanium aluminum carbide, titanium carbide and the like, and the anti-cracking agent is prepared by mutually modifying boron phenolic resin, mesophase pitch, artificial graphite powder and silicon carbide fibers. According to the refractory material, the metal silicon powder is adopted to improve the wear resistance and oxidation resistance, the titanium aluminum carbide is adopted to improve the oxidation resistance, the titanium carbide is adopted to improve the strength, and the surface-modified and film-formed anti-cracking agent is adopted, so that the thermal shock resistance is greatly improved, and the thermal expansion rate and the slag erosion rate are reduced. In addition, by adding titanium aluminum carbide, the strength and thermal shock resistance can be improved to a certain extent, the oxidation resistance is good, and the erosion resistance is improved. The refractory material can be used for high-carbon steel and low-carbon steel, and is particularly suitable for casting high-oxygen steel, calcium-treated steel and high-manganese steel.
