There are many kinds of carburizers, and their applications are also very wide. In the foundry industry, what aspects of carburizers can be used? The following is a detailed introduction of the carburizer manufacturer Zhengzhou mingmaite, hoping to help you
1; High quality castings: high quality carburizers, such as graphitization carburizers and graphite electrode carburizers, are used to produce ductile iron castings. The index is that the carbon content is 98.5% and the sulfur is 0.05%.
2; The production of ordinary nodular iron carburizer and gray iron for ordinary castings does not need to use coal based carburizer. The main indicators are that the content is 90%, 95%, and the sulfur content is preferably between 0.1 and 0.5,
3; In general, the most commonly used carbon additive for steel casting and steelmaking is coal, and the absorption rate is not high
4; For special castings, such as brake pads, more petroleum coke carbonaceous additives are used, and the absorption rate is more than 80%.
