harmophane



harmophane introduction:
1.Brown Corundum is fused in an electrical furnace by high temperature.
2.Its main raw materials are bauxite.anthracite.it dispaly brown.its chemical composition contains Al2O3,a small amount of
SiO2.TiO2.and Fe2O3.etc.the microhardness is 1800-2200kg/mm2.
3.The toughness is higher than silicon carbide.abrasive articles made of it are suited for grinding
metals of highten sile strength such as steel.annealed malleableiron and hard high-class
refractory products.the degree of refractory is up to 1850 centgrade.
harmophane advantage:
1,Grinding short time, high efficiency, low price
2,Good toughness and hardness modest, recyclable
3,The chemical stability, wear-resisting, acidproof alkali
harmophane uses:
1. Sandblasting
2. Free grinding
3. Resin rein-forcing
4. Tu attach abrasive
5. Functional packing
6. The filter medium
7. Hydraulic cutting
