For cast steel smelting or electric furnace smelting in casting smelting industry, the core of carburizing technology is to use carburizer with low sulfur, low nitrogen and high porosity.

In order to ensure that the carbon content of steel smelting increased, and to ensure that sulfur, nitrogen and other impurities as little as possible.

The main producing areas of petroleum coke are Jiangsu, Liaoning, Tianjin, Shandong and so on.

Among them, the graphitized petroleum coke additive provided by jinzhaochuan carbon of Lianyungang, Jiangsu Province, China, uses petroleum coke with low sulfur and low nitrogen. After graphitization, the carbon content is as high as 99%

The porosity of the carburizer also plays a crucial role in the carburizing effect and the absorption rate of the carburizer. Through the production process, all the pores of the petroleum coke additive are opened to maximize the specific surface area of the carbon additive. The product has super permeability and can be quickly dissolved in the molten steel to maximize the absorption rate and effectively increase the carbon content of the smelting steel.
