ABSTRACT:
A consumable lance for simultaneously reheating and desulfurization of a molten metal bath includes an internal circuit for delivering oxygen below the slag metal interface and an external circuit for delivering a desulfurizing agent to the slag metal interface. Improved desulfurization and reheating results are achieved.
