Chrome Corundum Wholesale Suppliers South Korea

There are also advantages and disadvantages of aluminum oxide abrasive. When we select brown corundum, we mainly look at its toughness. The higher the toughness is, the better the quality is. In fact, the toughness of aluminum oxide abrasive blasting grit is directly related to the quality of materials used to produce brown jade. Generally speaking, the better the quality of raw materials, the higher the quality of brown jade produced.

The toughness is also particularly good. Of course, the toughness of brown jade is related to the quality of brown fused alumina price production equipment. There is also a certain relationship between the technical level of operators. The higher the carbon content, the worse the toughness of brown jade. Generally, brown jade with low carbon content will not burst, and the degree of silicon carbide abrasive agglomeration is particularly high. At this time, the brown jade will appear obvious blue black. 


The toughness of brown fused alumina is mainly determined by three factors: the aluminum content of raw materials, the aluminum content of raw materials directly determines the aluminum content of finished products, the higher the aluminum content, the better the toughness, which is also a very important reason that emery abrasive raw materials must be bauxite. The carbon content of brown jade is opposite to that of aluminum content.


In the later stage of the brown jade processing, the white alumina products are put into the furnace to be re forged, which can prevent the color of the brown jade from changing. Because its chemical composition and physical properties are close to white corundum, it is called sub white corundum. Volume density ≥ 3.8g/cm2, fire resistance ≥ 1850 ℃. The product has the hardness of green silicon carbide and the toughness of brown corundum.


Low carbon sub brown aluminum oxide is made of high-quality bauxite, which is melted in the electric arc furnace at a high temperature of over 2000 ℃ and processed by a special process. It is an ideal high-grade refractory and grinding material. Because its chemical composition and physical properties are close to that of dense corundum, it is called bauxite dense corundum. It is an ideal substitute for synthetic corundum and dense corundum in the field of refractories.


It has the advantages of high temperature resistance, corrosion resistance, erosion resistance, black corundum low porosity, stable hot performance, etc., and has the characteristics of non initiation and non pulverization. It is an ideal substitute for white corundum and dense corundum, with black silicon carbide specifications of 0-1mm, 1-3mm, 3-5mm, 5-8mm, 200 mesh, 320 mesh, etc. it is mainly used in the production of refractory ramming materials, castables, and unshaped materials.


Fused bauxite dense corundum is a kind of brown aluminium oxide refractory raw material specially designed for iron channel materials, gun slurry materials, prefabricated parts, etc. of large steel plants. Its most outstanding characteristics are good thermal shock performance, erosion resistance, corrosion resistance and low porosity. The content of Al2O3 in the aluminum oxide grit chemical composition is more than 98%. Most of them are exported and a small amount of them are supplied to China.
