Description

technical field [0001] The invention relates to the technical field of performance research of inorganic non-metallic materials, in particular to a system and method for evaluating the reaction behavior of non-oxide materials under complex stress. Background technique [0002] High-temperature industries such as iron and steel metallurgy are important basic industries of the national economy, and their long-term and stable operation in extreme environments cannot be separated from the strong guarantee of high-temperature structural materials (ie refractory materials) used as linings. Compared with oxide materials, non-oxides (carbides, nitrides, borides, etc.) and their composite materials have better thermal shock stability and slag erosion resistance. Compared with traditional carbon composite materials, this type of material not only has high strength and excellent oxidation resistance, but also basically does not pollute molten steel. Therefore, they are ideal materials...
