High-Temperature Resistance for Demanding Environments
- Product Introduction
Products Description
We craft our Brown Fused Alumina 240# through precision smelting of premium bauxite, anthracite, and iron fillings in high-intensity electric arc furnaces. This process yields a product with 95–97% Al₂O₃ purity – containing a small amount of Fe,Si,Ti that enhance its structural integrity.
Brown fused alumina has good high temperature resistance,corrosion resistance and other properties, widely used in iron and steel,cement, glass and othe industries of thermal equipment,and also is irreplaceable high-grade refractory material in chemical industry.Because of iths high hardness and good grinding performance,it is an indispensable main material for all kinds of abrasives in the manufacturing industry.

Detailed picture
quality abrasive grade bauxite
Fanchuang workers select high-quality grinding grade bauxite for smelting to ensure the quality from the root.The content of Al2O3 is up to 85%.
Secondary refining
All brown corundum is refined twice for an additional three hours after industry standard smelting time,in order to improve product quality.
Strict grading
After smelting,the brown corundum blocks are manually screened and graded by workers to ensure that each batch is a high-quality product.
Perfect technology
Our excellent technological level has created high quality brown fused aluminum oxide,with relatively low cost and remarkable product effects.We use famous and high-quality high-power magenetic separators with 5 channels to strongly remove silicon&iron impurities to ensure product quality.
Strict quality control
We have excellent talents of management,professional technical team,strict quality testing procedures.We are scrupulous about every detail,thus our professional QC team will carry out strict quality inspection on every production process.
Products usage
1. High-Performance Refractory Solutions
FANCHUANG Brown Corundum serves as a critical raw material in producing high-grade refractory products, including refractory castables, bricks, and linings. Its high melting point and thermal stability ensure prolonged service life in extreme conditions, making it ideal for furnaces, kilns, and high-temperature industrial equipment.
