[0002] Magnesia carbon brick is a high-performance refractory material, usually made of magnesia and graphite as the main raw materials. It has excellent slag resistance, fire resistance and thermal conductivity. It is often used in the steel smelting industry as a lining material for high-temperature process equipment such as converters and electric furnaces. Magnesia carbon brick also has the characteristics of corrosion resistance and wear resistance. It is stable at high temperatures and is one of the important refractory materials. It is widely used in high-temperature processes in the steel, non-ferrous metals and other industries.

[0003] The problem with the existing technology is that in order to evaluate the structural strength and safety of the material, the produced magnesia carbon bricks need to be subjected to a compressive strength test. The traditional testing methods are basically divided into manual testing, laboratory testing, chemical analysis and optical microscope observation. These methods are relatively cumbersome to operate, which increases the difficulty of the test and is not conducive to the rapid and accurate testing of magnesia carbon bricks. Therefore, we propose a magnesia carbon brick performance test bench. Utility Model Content
