Analysis of the use of recarburizer manufacturers

In the steelmaking process, due to incorrect batching or feeding operations, excessive decarburization will result, and sometimes the carbon content in the steel will not meet the requirements. At this time, it is necessary to add carbon to the steel. With regard to the tips for using recarburizers, I will briefly introduce them below.


In the converter smelting of medium carbon steel and high carbon steel, petroleum coke contains almost no impurities and is used as a carbon enhancer. The recarburizer for top-blown converter steelmaking requires high carbon solid content, low ash content, volatile matter, sulfur, phosphorus, nitrogen and other impurities, dry, clean and medium particle size. If the particle size is too fine, it will burn easily. If the particle size is too large, it will float on the surface of molten steel and will not be easily absorbed by molten steel. It is suitable for induction furnace smelting, but its specific use varies with process requirements.

The recarburizer for intermediate frequency smelting can be added to the lower furnace according to the ratio or carbon equivalent requirements. The results show that the recovery rate of this method can reach more than 95%. The temperature of the molten iron rises, and the carbon is dissolved and absorbed by electromagnetic stirring or manual stirring. The recovery rate is about 90%. In this case, it will be immediately added to the molten iron and pressed into the molten iron together with the solid charge to prevent it from being exposed to the surface of the molten iron. This method can increase the carbon content of the molten iron by more than 1.0% .

The above is the entire content of the recarburizer manufacturer's analysis of the use of tips, thank you for your patience to read, if you have more product questions, you can directly call our company.
