Semi-coke
Semi-coke is light black, characterized by high fixed carbon, high specific resistance, high chemical activity, low ash content, low sulfur and Low phosphorus It is wildly applied to such industries as chemical industry, metallurgic industry, and gas- making industry to produce calcium carbide, ferroalloy, ferrosilicon, silicon carbide, silicomanganese, fertilizer, etc.
Semi coke is made from high grade Jurassic coal as a new type of carbon material. It can substitute some metallurgical coke in producing ferroalloys products. Semi coke is using in smelting too.
