PROCEDURE FOR MELTING IRON-CARBON ALLOYS IN INDUCTION FURNACES Russian patent published in 2010 - IPC C21C1/00 C21C1/10 

FIELD: metallurgy.

SUBSTANCE: invention refers to ferrous metallurgy, particularly to melting iron-carbon alloys in induction furnaces. The procedure consists in charging metal part of the charge, in melting and in alloying melt with silicon and carbon containing materials. Alloying is carried out with a complex mixture containing silicon and carbon at ratio C_Σ: Si=(25÷90):(0.5÷65), where Si is contents of silicon in the complex mixture, and C_Σ - is summary contents of carbon in the complex mixture. Also silicon is present in the composition of the mixture as silicon carbide metallurgical and/or its slimes, while carbon is present as heat treated carbon containing materials of electrode production and/or graphite.

EFFECT: facilitating melting iron-carbon alloys with preliminary specified properties and grade contents of silicon and carbon in melt; ensuring flexible corrections of its chemical composition at various stages of melting; reduced chill in iron and increased graphitising property.
