Brown Aluminium Oxide Abrasive
Brown fused alumina for refractory using high-quality calcined bauxite, coke, and iron by controlled melting in an electric arc furnace at high temperatures.
Brown fused alumina for refractory 0-1mm 1-3mm 3-5mm 5-8mm production process:
Brown Fused Alumina Refractory uses the high-quality bauxite as raw material, mix with anthracite and iron fillings, melting at 2000℃ in the electrical arc, then crushing and screening the various size.
Application of brown fused alumina for refractory 0-1mm 1-3mm 3-5mm 5-8mm:
Brown Fused Alumina is utilized within the refractory industry to manufacture high alumina fired and monolithic refractory products like bricks and pre-cast shapes. Unshaped refractory like gunning material, ramming refractory mixes, refractory castables, refractory mortars refractory raw materials.
Chemical compositions of brown fused alumina for refractory 0-1mm 1-3mm 3-5mm 5-8mm:
Physical properties of brown fused alumina for refractory 0-1mm 1-3mm 3-5mm 5-8mm:
– Pressure blast systems
– Injection blast cabinets
– Cleaning metallic surfaces with removal of material (abrasive effect)
– Removing rust and scale from metallic surfaces
– Removing tempering colour
Surface finishing:
– Creating a matt finish on surfaces
– Producing specific visual effects
Other:
– Roughening metallic surfaces
– Creating a matt finish on glass
– Deburring
– Processing very hard components
