DEOXIDIZING METHOD FOR CONVERTER REFINED MOLTEN STEEL

PURPOSE:To control the amt. of addition of a deoxidizing agent accurately by subjecting the molten steel which is desiliconized, dephosphorized and desulfurized to slagless refining so as to contain slag at a specific amt. in a bottom blown converter, and adding the deoxidizing agent at the amt. cor...

Zusammenfassung:	PURPOSE:To control the amt. of addition of a deoxidizing agent accurately by subjecting the molten steel which is desiliconized, dephosphorized and desulfurized to slagless refining so as to contain slag at a specific amt. in a bottom blown converter, and adding the deoxidizing agent at the amt. corresponding to the measured amt. of dissolved oxygen after tapping. CONSTITUTION:The molten steel which is beforehand desiliconized, dephosphorized and desulfurized is charged into a top and bottom blown converter and is subjected to slag min. refining or slagless refining in such a way that the slag is contained at
