Shaping Precision: Abrasive Raw Materials in Manufacturing Processes
Brown fused aluminium oxide is one of the most basic abrasives, widely used in many fields due to its relatively low price. Do you know the standards for chemical composition testing of brown fused aluminium oxide? brown fused aluminium oxide is made by melting high-quality alumina, iron filings, and smokeless coal in an arc, and then crushing and shaping it with a self-grinding machine, removing iron through magnetic separation, and screening into various particle sizes.
Garnet sand and brown fused alumina for abrasive are essential grinding materials in industrial production. Do you know the differences between garnet sand and brown fused aluminium oxide? Today, we will introduce the differences between them.
The chemical composition should be tested according to the brown fused aluminium oxide chemical analysis method and the white corundum and chromium corundum chemical analysis methods.
The particle size composition of brown fused aluminium oxide abrasives should be tested according to the measurement method of grinding material particle size composition.
The allowed content of magnetic materials and ferroalloy particles should be tested according to the content of grinding magnetic materials.
The density of brown fused aluminium oxide should be tested according to the relevant standards.
Each batch of brown fused aluminium oxide products should be inspected and accepted according to technical conditions and marked as qualified.
Differences in production process
Garnet sand is a refractory material particle made of high-quality alumina vanadium soil by electric melting, granulation, and screening. brown fused aluminium oxide is made by melting high-quality alumina, iron filings, and smokeless coal in an arc, and then crushing and shaping it with a self-grinding machine, removing iron through magnetic separation, and screening into various particle sizes.
Differences in product characteristics
Garnet sand particles are spherical, have good fluidity, are easy to compact, have a smooth surface, have a dense structure, a small surface area, high refractoriness, low thermal expansion coefficient, high impact resistance, are not easy to produce dust, are conducive to environmental protection, and have good recyclability.
Brown fused aluminium oxide is characterized by high purity, good crystallization, strong fluidity, low linear expansion coefficient, dense texture, high hardness, high toughness, spherical particle shape, and corrosion resistance.
Differences in product uses
Bulk garnet abrasive sand is mainly used in shell casting, precision casting; lost foam casting, large-scale steel casting, coated sand casting, V-process casting, investment casting. Brown fused aluminium oxide is suitable for manufacturing ceramics, resin high-consolidation abrasive tools, as well as grinding, polishing, sandblasting, precision casting, refractory materials, etc.
