摘要：
An oxygen/carbon blowing lance assembly for directing a supersonic flow of oxygen and a flow of graphite against the surface of molten bath in a steelmaking electric furnace. The two flows impinge upon the slag surface at discrete separate areas in the slag and the supersonic oxygen flow acts to emulsify the slag. The lance assembly includes a coolant shut off valve to prevent loss of coolant upon failure of the nozzle. The housing of the lance assembly includes a modular design for ease of maintenance.
