Main properties and uses of first-class brown fused alumina refractory sand

The grade of brown corundum

The main component of brown corundum is alumina, and the grade is also distinguished by the aluminum content.

The main use of first-class brown fused alumina refractory sand

(1)  cast steel sliding nozzles are used to smelt rare and precious metals, special alloys, ceramics, iron-making blast furnace linings (walls and pipes); physical and chemical utensils, and spark plugs, Heat-resistant, and anti-oxidation coating.

(2) Brown corundum has the characteristics of high hardness, good wear resistance, and high strength. In chemical systems, it is used as various reaction vessels and pipelines, components of chemical pumps; mechanical parts, and various molds, such as wire drawing dies, extruding pencil core die mouth, etc.; making knives die abrasives, bulletproof materials, @ joints, sealing die rings, etc. www.xinyugangyu.com

(3) Corundum insulation materials, such as corundum light bricks, corundum hollow balls, and fiber products, are widely used in furnace walls and furnace tops of various high-temperature furnaces, which are both high temperature resistant and thermal insulation.

Xinyu brown corundum grain size sand is made by hand-selecting brown corundum blocks, which are processed by rollers, ball mills, Barmac, and other equipment. The grain size ranges from f8 to f325. It is mainly used for polishing, grinding, industrial grinding, etc. It is required to be processed by water washing, pickling treatment, and other methods, which can meet the different needs of customers. Low carbon brown corundum is reprocessed before the furnace and special process to reduce the content of residual carbon in brown corundum, so that the product does not pulverize, does not burst, and has high toughness during use. It is the preferred raw material for abrasives and refractory industries. Mainly used for ceramic abrasives, high-grade abrasives, organic abrasives, abrasive belts, coated abrasives, etc. The residual carbon content is divided into calcined brown corundum c ≤ 0.05%, low carbon brown corundum c ≤ 0.10%, and ordinary brown corundum c ≤ 0.10% Corundum c ≤0.15%.
