Advantages of using brown corundum material
Brown corundum has a glass luster and a hardness of 9. The specific gravity is 395-410. It is formed under the condition of high temperature aluminum-rich and silicon-poor C, which is mainly related to magmatism, contact metamorphism, and regional metamorphism. Corundum is a man-made material smelted by a mining furnace with bauxite as the main raw material. It can be used as abrasive and refractory products. Brown corundum is based on bauxite, coke (anthracite), and iron filings. It is crystallized by high temperature melting in an electric arc furnace. It has high hardness, toughness, sharp particles, strong grinding power, high temperature resistance, High efficiency and other characteristics are high-quality abrasive materials and advanced refractory materials.
Brown corundum powder is the main raw material for the production of artillery mud, and its quality has an important influence on the resistance to slag iron erosion, thermal shock resistance, and high temperature strength of the artillery mud. In the process of preparing the gun mud, when the SiC powder and the binder are added in the same amount, the larger the SiC powder particle size, the smaller its surface area, and the relatively large amount of binder wrapped on the surface of the SiC particles, which reduces the interaction between the SiC particles. The moving friction improves the plasticity of the gun mud. If the gun mud is dried, the strength of the gun mud after drying mainly depends on the bonding effect of the binder and the clay. As the particle size of the SiC powder increases, its surface wraps. The binding agent increases, so the strength is greater after drying.
