Semi-coke:
Rongxing semi-coke is a non-viscous or weakly viscous, high-volatility bituminous coal that undergoes dry distillation and pyrolysis under medium and low temperature conditions to obtain a solid carbon product with lower volatile content. As a new type of carbon material, semi-coke has gradually replaced metallurgical coke due to its high fixed carbon, high specific resistance, high chemical activity, low volatilization, low aluminum, low sulfur, and low phosphorus. ). Semi-coke is widely used in the production of calcium carbide, ferroalloys, ferrosilicon, silicon carbide and other products. It has become an irreplaceable carbon material, replacing coke (metallurgical coke) and widely used in chemical, smelting, gas production and other industries.

Applications of Semi-coke:
Semicoke can be used in ferroally production to replace the metallurgical coke, blast furnace injection, as a sintered fuel to produce iron. It’s a new environmental materials to be applied wildly in different industries.
