Tilting Furnace Barmac Crushed White Fused Alumina WFA for Refractory Castables

1. White Fused Alumina Descriptions

White fused alumina is fused by alumina powder by melting above 2000℃ in electric arc furnace and cooling, through crushing, shaping, deironing and then divided into a variety of particle size by screening. It has the performance of high purity, self-sharpening, acid and alkali resistance, high temperature thermal stability and lower toughness. Its hardness is slightly higher than brown fused alumina. The abrasives made of it are suitable for manufacturing ceramic porcelain, resin consolidation abrasive and grinding, polishing, sandblasting, precision casting (Precision casting special corundum) etc.

5. White Fused Alumina Applications

Gunning materials are high-temperature refractory materials. These materials are placed using varying types of Gunning equipment through a nozzle with additions of Water and Air. These materials are designed to stick in place and set quickly when applied to the required area, such as walls and roofs.

Due to the nature of their placement using compressed air, the particle size is smaller than general castables, this aids in the reduction of a rebound off the wall.

Our customers use gunning materials in a range of industries from Incineration and Petrochemical, to Iron and Steel business sectors.
