Supply a two corundum

A supply two corundum production process: also known as carborundum, is bauxite, coke (anthracite) as the main raw material in electric arc furnace at high temperature smelting. The main components of AL2O3, and TiO2. There is also a small amount of SIO2 and Fe2O3, performance: high temperature resistance, corrosion resistance, high hardness, high strength, wear resistance, good crystallinity, low coefficient of expansion. Microcrystalline hardness: Nu spectral hardness HV1800-2200kg / mm2, Mohs hardness 9.0 bulk density of 3.85 / cm3 ,, the highest temperature 1850 ℃, melting point 2250 ℃ color: dark brown, dark blue after calcination. Uses: 1. Sandblasting corundum, 2. Free grinding, 3. Resin abrasive, 4 coated abrasives, abrasive water cutting 5, 6, refractories. Corundum functional filler - mainly used for automobile brake parts, special tires, specialty construction products in areas such as construction of motorways, runways, terminals, parking lots, industrial flooring, sports and other wear-resistant materials; filter Media - is a new abrasive applications, the use of particulate media filter bed layer media, clean drinking water or waste water, is home to the new water filtration materials, especially for non-ferrous metal processing, oil drilling mud weighting agent: Name Specification Main Index Density g / cm3 purposes appearance AL2O3 Fe2O3 SiO2 corundum refractories ≥95 ≤0.3 ≤1.5 3.85 a brown-red particles ≥90 ≤1.3 ≤1.5 3.85 times a grinding, polishing brown particles two ≥85 ≤1.8 ≤ 1.5 3.8 grinding, polishing, sandblasting brownish-gray granules times two ≥80 ≤2.3 ≤1.5 3.75 polishing, grinding gray particles three ≥70 ≤4.3 ≤1.5 3.5 floor gray particles used size: 16 #, 24 #, 30 # , 36 #, 46 #, 60 #, 80 #, 100 #, 120 #, 150 #, 180 #, 200 #, 325 #.
