How to choose high-quality carbon additive for steelmaking

Steelmaking carbon additive is a reasonable type of product for the research and development and manufacturing of steelmaking process products. A certain amount of steelmaking carbon additive can be added in ironmaking to adjust the carbon composition in the molten steel, and then adjust the ductility and strength of the steel. High-quality steelmaking carbon additive usually fully plays the ideal practical effect in the smelting plant. Therefore, choosing high-quality steelmaking carbon additive has become a key link in the steelmaking process. So, how to choose a carbon additive for steelmaking? Authoritative experts say don't make mistakes!

The usage method of petroleum coke carbon additive and the importance of detailed calibration of nitrogen composition

Of course, for the calcined petroleum coke carbon additive, since it has not undergone high-temperature calcination, the calcination temperature will be slightly lower and the calcination time will not be long enough. This type of carbon additive, as the carbon appears in the form of high-purity graphite, has excellent digestion and absorption in the furnace. It is basically the same as the high-temperature calcined petroleum coke mentioned above, and its price is around 5,000 yuan. The staff of the smelting plant all think that this type of carburizer is very good, with low sulfur content and low nitrogen content.
