Semi Coke, also called gas coke, lam coke, is made from high quality anthracite coal, under a high temperature(1300â??) process. They are widely used for calcium carbide, ferro alloys manufacture or non-ferrous metals smelting, manufacture or other related metallurgical industries, because of its special physical and chemical characteristics: high fixed carbon content, low sulfur and low phosphorus for content.
Semi coke, also called gas coke, lam coke, is made from high grade Jurassic coal, under a high temperature(1300â??) process. They are widely used for calcium carbide, ferro alloys manufacture or non-ferrous metals smelting, manufacture or other related metallurgical industries, because of its special physical and chemical characteristics: high fixed carbon content, low sulfur and low phosphorus for content.
Semi coke powder can be used in blast furnace instead of coal injection in steel-making ;
â?¢ 0-8mm semi coke can be used for sintering Mn ore in process of production SiMn; or using in other sinter mill.
â?¢ 6-18mm semi coke can be used in producing Ferro nickel , Ferro silicon ,Calcium Carbide and other ferro alloys.
Sepcification of semi coke:
FC: 84% min
Ash: 9% max
VM: 8% max
Sulfur: 0.4% max
Moisture: 15% max
Size: 6-18mm, 18-35mm, 10-30mm, 30-60mm
Hard coke (ham coke) is formed by heating of coking / semi coking coal in absence of air, which form a coherent bead of strong and porous mass, free of volatiles. Hard coke is a fuel with few impurities and a high carbon content. It is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulphur bituminous coal. Cokes from coal are grey, hard and porous.
It is mainly used as a fuel in metallurgical industries, domestic applications and chemical industries. Besides of fuel, it is also used for its carbon considerations by various industries.
