Graphitized petroleum coke recarburizer is to place petroleum coke in a graphitization furnace. After a high temperature of up to 3000 degrees, the amorphous chaotic structure carbon crystal of the petroleum coke is transformed into hexagonal mylonite structure crystalline carbon, that is, the petroleum coke becomes High-purity graphite. This whole process is called graphitization, and the petroleum coke that has been solved through the whole process of graphitization is called graphitized petroleum coke, also known as “graphitized coke”.

The key origins of China’s petroleum coke recarburizer are Liaoning Province, Tianjin City, Shandong Province and other places. Among them, the Liaohe Oilfield is the origin of low-sulfur petroleum in the world, and therefore petroleum coke contains less sulfur. For steel castings or furnace smelting in the foundry industry, the key to recarburization technology is the application of low-sulfur, low-nitrogen, and high-porosity recarburizers.

The porosity of the recarburizer also has a particularly important effect on the actual effect of the recarburizer and the digestibility of the recarburizer. According to the production process, the porosity of the petroleum coke recarburizer is turned on to promote the bulk density of the recarburizer and make it permeable It can quickly melt into molten steel to promote digestibility and increase carbon efficiency.
