As a petroleum coke carburizer manufacturer, today Xiaobian to talk to you about what carburizer is.
The main component of carburizer is carbon, and its function is carburization, but the quality of different carburizers is not the same, for example: graphite-based, calcined petroleum coke-based,
Calcined coal, natural graphite, waste electrode broken, particle recycling and so on, the main composition is carbon, it is certain that the higher the carbon content, the lower the basic impurities (basic impurities generally refer to ash, volatile, etc.).
Another is the content of sulfur and nitrogen in the composition. The role of sulfur is basically clear. A certain amount of sulfur in cast iron can better improve the physical properties of castings. In recent years, nitrogen content has also been widely studied. Nitrogen content is too high.
The formation of nitrogen pores, nitrogen content is too low, the hardness of castings does not go up, ferrite is more, generally speaking, the nitrogen content of molten iron is controlled between 80ppm.
Carburizing agent is suitable for smelting in induction furnace, but it is not the same according to the requirements of the process.
When the carburizing agent is used in the melting of medium frequency electric furnace, the carburizing agent can be added to the lower part of the electric furnace according to the ratio or carbon equivalent, and the recovery rate can reach more than 95%.
If the carbon content is insufficient to adjust the carbon content, first clean the slag in the furnace, then add the carburizing agent, and make the carbon dissolved and absorbed by molten iron, electromagnetic stirring or artificial stirring, the recovery rate can be about 90%. If the low temperature carburization process is adopted,
That is, the furnace charge only melts part, and when the molten iron temperature is low, all the carburizing agents are added to the molten iron at one time, and the solid charge is used to press it into the molten iron to prevent it from exposing the molten iron surface.
By this method, the carburization of molten iron can reach more than 1.0%.
