80 Grit Aluminum Oxide Blasting Media Wholesale

We know that the grade of brown fused alumina manufacturer is classified according to the aluminum content. The second grade brown corundum is also made of high-quality bauxite through purification, impurity removal and crystallization in high temperature above 2200 ℃ in the electric arc furnace, and then sorted, broken, screened and screened into 100 grit aluminum oxide blast media products of various particle sizes.

The granularity of white fused alumina manufacturer products can be produced according to international standards and national standards, and can also be processed according to the requirements of users. The general particle size is F4 ~ F320, and its chemical composition varies according to the pink alumina particle size. Because of the self grinding process, the particles are mostly spherical particles, the surface is dry and clean, and easy to bond.


It is a brown artificial corundum made by melting and reducing bauxite, carbon and iron scraps in an electric furnace. Because of its high temperature resistance, corrosion resistance, high strength and other properties, the steel pouring sliding nozzle is used to smelt the lining (wall and pipe) of rare metals, special alloys, ceramics, iron smelting blast furnace; physical and black aluminium oxide chemical vessels, spark plugs, heat-resistant and anti-oxidation coating.


brown fused alumina, also known as corundum, is mainly composed of Al2O3, with a content of 94.5% - 97%. In addition, it contains a small amount of Fe, Si, Ti, etc. Low carbon brown corundum is reprocessed in front of furnace and special process to reduce the content of residual carbon in brown fused aluminium oxide, so that the products will not be powdered, burst and tough in use, which is the preferred raw material for abrasives and refractories industries. 


The alumina content of the second grade white fused alumina suppliers is ≥ 85%. The prominent feature is that the crystal size is small and impact resistant. Generally, the sulfur content in brown corundum can not reach the level that causes problems. In the oxidation atmosphere, the sulfide in the white fused alumina price is unstable when the temperature is increased. These bubbles and spots due to local melting may cause the product to be scrapped. 


The source of sulfur is usually brought in by coke or coal used as reducing agent during brown aluminum oxide smelting. From the point of view of environment and product quality, carbon sources with low sulfur content are needed. In the smelting process, the carbon source with high sulfur content will cause the furnace to emit bad smell smoke. If sulfide formed by oxidation of sulfur and other pink aluminium oxide metal compounds in smelting continues to exist in smelting process.


Sulfur in black fused alumina often leads to foaming and loose structure of products produced or used in high temperature oxidation atmosphere. Iron sulfide will oxidize in the oxidation atmosphere above 1180 ℃, while sulfur will become Sox gas. The vaporization and escape of sulfur will cause the formation of bubbles, and the residual iron oxide will cause the local melting of black aluminum oxide media based on ceramic materials.


The content of brown aluminium oxide sulfur in coke used as reducing agent is generally specified as Lt; 1%. The sulfur content in coal ranges from 1% to 10%. In some coal, sulfur already exists in the form of pyrite (FeS2). As the smelting of brown corundum is carried out in reducing atmosphere, it can be imagined that pyrite will continue to exist in the smelting process. In order to minimize sulfur pollution, low sulfur coal should be used as reducing white aluminum oxide abrasive agent.
