Description

technical field [0001] The invention relates to the field of test equipment. Specifically, it is an experimental device for quickly testing the performance of refractory materials against slag erosion. Background technique [0002] Refractories are necessary materials for various high-temperature equipment, and are widely used in metallurgy, cement, ceramics, glass and other industries. The erosion of refractory materials by slag is one of the main reasons for the damage of refractory materials. At present, the test equipment for the slag erosion resistance of refractory materials is not perfect. Generally, there are two commonly used ones: one is the use of intermediate frequency electric furnaces, and the other is Bottom rotary slag resistance test furnace. Among them, the former has problems such as a large amount of sample cutting and preparation, high assembly requirements, and a large amount of furnace building and dismantling, and cannot accurately control the tempe...
