White corundum is a white abrasive made from industrial alumina powder (Al2O3) with a content material of more than 98% and a small sum of iron oxide and silicon oxide. It is a white abrasive which is melted at higher temperature. Its hardness is marginally greater than that of brown corundum and its toughness is a bit decrease. It is manufactured by smelting and cooling above 2000 levels in arc, grinding and shaping, eliminating iron by magnetic separation, and sieving into several types of granularity. It is compact in texture, high in hardness and sharp in form. It is suitable for making ceramics, resin-bonded abrasives, grinding, sprucing, sandblasting, precision casting (corundum for precision casting), etc. Manufacture of large-quality refractories, code identify “WA” in the international frequent expectations, national standards consistent, mo EPT for export, but also a certain quantity of provide to domestic consumers.
The solution dimension is produced in accordance to intercontinental standards and countrywide specifications, and can be processed according to person specifications. The common size is F4~F220 and w63-w2.5 has diverse chemical composition based on the particle measurement. The notable feature is that the crystal measurement is tiny and influence-resistant, if the grinding equipment is utilized to crack, the particles are largely spherical particles, the area is cleanse and simple to bind.
Use:
The abrasive too EPT made of white corundum are suited for grinding high carbon metal, plateau steel, substantial pace steel and quenched metal with more challenging and more robust tensile toughness. It is suited for strong framework and coated abrasive tools, damp or dry jet sand, extremely-good grinding and sharpening suited for crystal and digital industries and making substantial-grade refractories.
It can also be utilized as grinding and sprucing resources, precision casting sand, spraying components, chemical cataly EPT carrier, unique ceramics, innovative refractories, and so on. It is characterized by strong chopping power, very good chemical stability and great insulation.
Relevant industries:
Bearing market
1. It is ideal for swift elimination of oxide scales on the floor of bearing rings after warmth therapy.
2. It is ideal for the deburring and polishing of stamping and blended iron retainers. For copper holders, the finishing procedure fully replaces the original pickling method. Chamfering, deburring and sprucing not only increase the item high quality, but also enhance the working environment, in line with the nationwide environmental security demands.
three. It is suitable for surface area polishing of bearing cylindrical roller, tapered roller, spherical roller and needle roller, significantly improving the floor roughness and brightness.
Auto areas business
1. It is suitable for chamfering and deburring of various automobile stamping components, gears, die-casting aluminum shell parts, copper castings, crankshafts and camshafts.
2. It is suitable for surface sharpening of various piston couples, oil supply valve couples, piston rings, crankshafts and camshafts of different automotive engines, diesel engines and fuel injection pumps.
