Low Carbon Brown Corundum Material

Low carbon regular fused alumina is made by melting and reducing bauxite, carbon material and iron filings in electric arc furnace. It is also known as emery. It is a high-grade refractory raw material and abrasive. The Low carbon regular fused alumina supplied by our company has low residual carbon,the main component is Al2O3, with high purity, good crystallization, low expansion coefficient and good corrosion resistance,the application effect is higher than that of traditional regular fused alumina.

Description

1.Description:Low Carbon Brown Corundum is a high-grade refractory material, with less carbon residue, uniform and stable chemical composition, high density, low pulverization rate, high hardness and strong grinding force. The product is made of grinding grade bauxite by high temperature smelting at 2250 ℃.

2.Specification ofLow Carbon Brown Corundum: 2-3000 mesh

3.Application: the product can be used to make all kinds of high-grade castables, gunning materials, ramming materials and other fire-resistant products. It can also be used to produce brown corundum brick, sliding plate brick, widely used in steel, cement, petrochemical, abrasive and other industries

4.Storage and transportation: waterproof and moisture-proof plastic bag packaging, convenient for transportation. Store in a dry environment.
