Brown Fused Alumina
Introduction
Brown fused alumina refractoryis made from high quality bauxite by fusing in an electric arc furnace at high temperature.
It has good toughness and high hardness.
It is suitable for manufacturing of vitrified and resin bonded tools, and for lapping, polishing, and sand blasting and sand cleaning.
Properties
The bauxite, coke (anthracite) as main raw material, by smelting at high temperature in the EAF, the main chemical composition: Al203, Ti02 also small amounts of Si02 and Fe203. Characteristics: Higher toughness than SiC, Microhardness 1800-2200kg/mm2, bulk density ≥ 3.85g/cm3, high temperature, high refractoriness 1850oc.
Usage: Made for abrasive, suitable for grinding high tensile strength metal, such as a variety of general-purpose steel, malleable iron and hard bronze, etc. It can also create high-level refractory material.
