Semi-coke is made by burning high-quality coal blocks. As a new type of carbon material, with its characteristics of high fixed carbon, high specific resistance, high chemical activity, low ash content, low aluminum, low sulfur, and low phosphorus, it has gradually replaced metallurgical coke and is widely used in the production of products such as calcium carbide, ferroalloy, ferrosilicon, and silicon carbide, becoming an irreplaceable carbon material. Semi-coke can replace coke (metallurgical coke) and is widely used in industries such as chemical engineering, smelting, and gas production.
