brown fused alumina/brown corundum/abrasives
used as refractory and abrasive raw material in sand blasting, steel and iron casting, ramming, grinding wheel making, polishing, ceramic raw material.
tilting furnace products, best quality, high temperature and compression resistence.
we can produce both refractory and abrasive kinds for brown fused alumina.
the grain size is 0-20mm, it can also be produced according to different requirement.
packing is 25kg woven bag. (0-20mm BFA) and (F14-220 BFA).
Brown fused alumina is manufactured in electric arc furnace, using bauxite as raw material. High hardness and toughness, it is an important raw material of abrasive and refractory industries. It can be used for belt, ceramic, coated, high-grade, and organic abrasives. The product can be used as abrasive and refractory material. The abrasive tools made by brown fused alumina are suitable for grinding carbon steel, normal alloy steel, malleable cast iron and hard bronze, etc. brown fused alumina can also be used for making fine quality refractory.
