A METHOD FOR CONVERTER STEEL DEOXIDATION WITH ALUMINIUM

A method for converter steel deoxidation with aluminium involves addition of silicon maintaining ferroalloys, addition alloys, slag forming mixture and aluminium to the steel teeming ladle. Metal and slag with aluminium are deoxidated serially in three stages: preliminary steel deoxidation (25-40 %)...

Zusammenfassung:	A method for converter steel deoxidation with aluminium involves addition of silicon maintaining ferroalloys, addition alloys, slag forming mixture and aluminium to the steel teeming ladle. Metal and slag with aluminium are deoxidated serially in three stages: preliminary steel deoxidation (25-40 %), slag deoxidation (10-30 %), and final deoxidation and alloying metal û the final amount of aluminium.
