Name
Carburant
Product Feature

High fixed carbon content, low sulfur content, stable recarburization and high carbon absorptivity

Application Scope

Used for recarburization of electro-smelting steel casting and iron casting
Particle Size: Common Used Particle Size: 0-10mm, or customizable

Usage

1) Adjust the carbon content during preparation, add the carburant into lower middle part of an electric furnace together with metal furnace burden according to the requirement of carbon content during steel (iron) liquid melting, do not stir slag while the carburant is melting, otherwise the carburant will be mixed in the waste slag and then carbon absorption is influenced. The carbon absorption rate can reach 90%-95%.
2) Adjust the carbon content after steel (iron) is melted, wherein the carburant can be added on the surface of the steel (iron) liquid and carbon will be dissolved and absorbed through eddy stirring or manual stirring of the steel (iron ) liquid during electro-smelting. The carbon absorption rate can reach 90%-95%.
