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.

Application • Semi coke powder can be used in blast furnace instead of coal injection in steel-making ;
• 0-8mm semi coke can be used for sintering Mn ore in process of production SiMn; or using in other sinter mill.
• 6-18mm semi coke can be used in producing Ferronickel , Ferrosilicon ,Calcium Carbide and other ferroalloys

Advantage of semi coke than Met Coke in production of Ferro-alloy smelting as deoxidizer

  • Semi Coke could improve the quality of the ferroalloy significantly (especially low aluminum alloy Al2O3≤0.1%).
  • Semi Coke could reduce unit electricity consumption significantly (nearly save more than 1000 KWHR, that means 8-10%)
  • Semi coke could lower the cost of raw material. Although the price of semi coke and coke is similar, but it’s far cheaper than charcoal and pet-coke
  • It’s very simple to replace coke, pet-coke and charcoal with semi coke. It’s no need to upgrade your equipment and the operation is easy and process is simple.
Semi coke is made from high grade Jurassic coal as a new type of carbon materia, we can also provide Coal Injection, Coke Fuel and other products.
