Semi-coke is fired from high-quality Jurassic coal. It has the characteristics of high fixed carbon, high specific resistance, high chemical activity, low ash content, low sulfur, low phosphorus, and low aluminum. It is widely used in the production of calcium carbide, ferroalloy, ferrosilicon, silicon carbide and other products, as well as in the chemical, smelting, and gas production industries. In recent years, Semi-coke has also been widely used in civil applications and industrial boiler fuels. The large-scale promotion of Semi-coke is the use, and it has attracted more and more attention and praise in various fields.
Semi-coke with a lump structure and a particle size generally above 3mm, and its color is light black. Semi-coke can be divided into large, medium, small and coke noodles. The particle size of the small material is between 6mm and 13mm, the particle size of the medium material is between 13mm and 25mm, the particle size of the large material is greater than 25mm, and the particle size of the focal plane is less than 6mm. The quality standard of Semi-coke is fixed carbon>82%, volatile matter<4%, ash content<6%, sulfur content<0.3%, moisture content<10%.
