The function of adding bauxite content in corundum is to stabilize the properties of corundum, and the application range of bauxite is particularly wide. It can be used in corundum production, electronics, petroleum, national defense and other industries. Bauxite in brown aluminum oxide is used half of the time. Bauxite can also be processed at high temperature to make refractory fiber. It can be used in industries with high fire resistance requirements. The fire-proof clothing used by fire fighters is made of fire-resistant fiber.

The iron plating treatment of brown corundum abrasive is a production process that uses ferrous sulfate and mineralizer as the plating solution for the plating treatment of white corundum. Compared with the general brown corundum abrasive, the indicators of the grinding amount, desanding amount and grinding effect of the products after the iron plating treatment are all due to the common products. Among them, the addition of pure calcium aluminate cement should be strictly controlled, generally 5% to 8%.

Too much addition will greatly reduce the high temperature performance of castable. At present, the domestic manufacturers mainly use blowing oxygen method, secondary calcination method and adding oxidant method to control the carbon residue of brown fused aluminum oxide, and achieved some results Brown corundum has many characteristics in the application process. If it is used in a suitable industry, then the characteristics of brown corundum are used as compensation materials. In a suitable industry, brown corundum not only plays a compensation role, but also has the role of improving the performance of products after manufacturing or stabilizing performance.

The smelting of Cr corundum is similar to that of white corundum. A small amount of Cr2O3 is added into the alumina powder as the main raw material. Due to the small amount of Cr2O3, it is mixed in batches according to the ratio of chromium oxide: aluminum oxide powder = 1:5, and then added synchronously with aluminum oxide powder. During the cooling process, sodium aluminate is also segregated in the middle and upper part of the melting block.

Function of white corundum: it has the characteristics of good hardness, high purity and thermal stability in use. According to these characteristics, white corundum can be used in construction, chemical industry, black aluminum oxide refractory material manufacturing, abrasive tool processing, abrasive material, filter water quality and other industries. According to its own characteristics and advantages, white corundum has a wide range of applications. Among the artificial corundum, white corundum has gradually become one of the most popular corundum.

Take out the furnace graphite, transport it to the graphite stacking yard, and sieve it to be less than 50 mm. Take the lower secondary products and transport them to the stacking yard for crushing. The crystallizing barrels of small furnaces are small, most of which have no cranes. Split the crystallizing barrels manually, and transport them to the designated place for grading by trolleys. Transport the secondary and amorphous products to be broken for use.

White corundum used in higher temperature has the same advantages of good thermal stability. After crushing, it is spherical in appearance, with high purity and uniform shape. Application scope of white corundum: it can be used for pink aluminum oxide refractory, sand blasting, grinding wheel production, surface coating of abrasives, fillers, aggregates and filtering water quality. The scope of these can be used has not been fully described, because more scope of use is still in discovery and experiment.
