Although, after a period of development, the types of carburants are increasing, and different carburants have different characteristics and are used in different fields. Low nitrogen carburizer, as one of many carburizers, has won the recognition of many users by virtue of its own advantages. So, what is the role of low nitrogen carburizer? To induction furnace to add more than 50-60% of the scrap, melting synthetic cast iron, the greater the amount of scrap added, the greater the nitrogen content of hot metal, because the synthetic cast iron liquid titanium, lead, antimony, and other harmful elements are very low, so low nitrogen carburizer should be used. If the nitrogen content of the carburizer is high, the synthetic nitrogen content will cause the casting to have nitrogen pores.
On the contrary, if the use of high nitrogen carburizer, due to the very low content of titanium in the hot metal, it is impossible to use Ti to consume a large amount of nitrogen, so that the casting is easy to appear because the nitrogen content is too high and nitrogen pores, fissured nitrogen pores or related defects. If the quality of the carburizer is not good, it will cause significant losses, especially emphasizing the melting of synthetic cast iron, and the key is to use calcined petroleum coke with good quality and low nitrogen content.
