Petroleum coke carburizer. In this way, petroleum coke can be better decomposed in molten iron. The mainstream carburizer on the market now is graphitized petroleum coke carburizer.
There are many kinds of raw materials for carburizing agents, and the production processes are also different, including wood carbon, coal carbon, coke, graphite, etc., among which there are many small types under various categories. Carburizers that are more effective generally refer to carburizers that have been graphitized. Under high temperature conditions, the arrangement of carbon atoms takes the microscopic form of graphite, so it is called graphitization.
Influence of the particle size of the carburizing agent: 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.
