company news about Graphitized petroleum coke carburizer

Graphitized petroleum coke carburizing agent is a high-purity carburizing agent. An appropriate amount of graphite, graphite coke, graphite slag and petroleum coke are mixed in a certain proportion in an electric arc furnace or induction furnace. The petroleum coke is carbonized at high temperature and graphitized. A product produced.

Graphitized petroleum coke carburizer has the characteristics of high purity, high temperature resistance, and high strength. It is widely used in foundry, metallurgy, refractory materials and other industries. In the casting industry: it is commonly used to adjust the structure and hardness of castings and extend the service life of castings. In the metallurgical industry: it plays an indispensable and important role in the smelting of steel and non-ferrous metals and as a regulating component in steelmaking.

Graphitized petroleum coke carburizer has high fixed carbon, high absorption and utilization rate, low sulfur and low nitrogen. It can effectively reduce pore inclusions, optimize graphite morphology, increase the spheroidization level and improve casting performance, thereby achieving the purpose of improving corporate efficiency.

The carburizing process of carburizing agent includes dissolution, diffusion and oxidation loss of carburizing agent. The particle size of the carburizer is different, and the dissolution, diffusion and oxidation loss rates are also different. The absorption rate of the carburizing agent depends on the combined effect of the dissolution and diffusion rate of the carburizing agent and the oxidation loss rate. Under normal circumstances, the carburizer particles are small, the dissolution rate is fast, and the loss rate is large; the carburizer particles are large, the dissolution rate is slow, and the loss rate is small. The choice of carburizer particle size is related to the diameter and capacity of the furnace. Generally speaking, if the diameter and capacity of the furnace are large, the particle size of the carburizer should be larger; conversely, the particle size of the carburizer should be smaller.
