ABSTRACT:
A protective device for a submersible lance to be used in a vessel of molten material, such as steel, prevents undesirable deposition of the material at the juncture of lance and probe by having in the lance a channel for gas, and by having between the lance and the probe a gas-conducting disk which projects this gas circumferentially onto the lower surface of the lance.
