High Hardness Brown Fused Alumina Fixed Furnace For Bonded Abrasives No Rust
Description:
Production process: sorting of the raw materials→electrolytic smelting→crushing→magnetic separation→filter→physical and chemical testing→packing→warehousing
In order to meet the demands of the refractory industry, we independently develop and produce RS brown fused alumina. Which is characterized by high purity,good crystal,strong fluidity,low coefficient of linear expansion,good corrosion-resistance and so on. RS Brown fused alumina could not burst,pulverise and craze in using course.
Brown Fused Alumina is fused in the electric-arc furnace under the high temperature of above 2250°C with high quality bauxite as raw material and matched by the carbon material and scrap iron .The degree of refractory is more than 1850°C.
