cheap brown fused alumina suppliers
Generally, there are two kinds of charge layout: The new charge method loads the new charge composed of silica sand and coke into the reaction zone. In the furnace bottom roasting method, the new material composed of silica sand and coke is first loaded into the furnace bed at the bottom of the furnace for roasting, the volatile components in the coke are removed and sintered into larger particles, and then put into the reaction area after the next furnace. At the beginning of power transmission, most of the current flows through the furnace core due to the formation of non decomposed graphite and silicon carbide. Fine powder is discharged from the upper part of the mill with the air flow, and is collected in the dust collection device, which is the product. The granular materials not carried away by the air flow, after overflowing the grinding disc, return to the mill inlet through the externally circulating bucket elevator, and enter the mill with the newly given raw materials to re-mill. Set grinding, drying, grading and conveying functions in one, relatively complex functions, convenient operation and adjustment, high degree of automation, single machine processing capacity. When the process method is applied to the newly-built. It is suitable for surface polishing of pavement, runway, special building and abrasives, steel, wood and glass. Sandpaper production is also commonly used. White corundum is widely used because of its excellent properties: high hardness and corrosion resistance. Impact resistance, high purity, no more impurities. At present, these use areas have been recognized by users. Among the artificial corundum, white corundum and brown corundum are the most popular. new charge method and furnace bottom baking method. There are different types of molding materials for the production of ceramic abrasive tools in China. Some factories have lower requirements for the strength of the wet billet. For example, the aluminum base plate is used for drying and the aluminum base plate is used for drying. Suction cup, the workshop floor is relatively flat, wet billet transportation conditions are good, etc. Therefore, low-dextrin dosage and wet molding material are used to ensure high dry billet strength to adapt to dry billet handling and kiln loading billet strength Requirements. Brown Corundum manufacturing equipment, the two processes of bauxite calcination and bauxite smelting are closely connected, and the bauxite discharged from the rotary calciner is directly added to the electric arc furnace with temperature; in the process of adding the bauxite to the smelting furnace, the bauxite passes through the charging bin set on the electric arc furnace, and a plurality of evenly arranged feeding bins connected with the charging bin. The feeding pipe above the smelting furnace is added to the electric arc furnace to make the bauxite evenly added to the electric arc furnace. A small amount of MgO will also have a larger effect. The internal force is called stress. Promoting the application of breathable bricks on ladle furnaces and out-of-furnace processing ladles has also achieved good results. The stronger the stirring force in the molten pool, the higher the qualified steel output. Rhenium is actually an indirect and stricter regulation of the content of iron oxide. The first grade brown corundum is suitable for precision casting, wear-resistant materials and other industries with high abrasive requirements.
