ABSTRACT:
The usual oxygen lance, and a coating lance, are disposed in upright and spaced-side-by-side relation for selective lowering into the BOF vessel when the latter is in the normal upright position it occupies for refinement of its metallic charge. Preferably, the coating lance is lowered into the vessel immediately after the latter has been charged with scrap and molten iron and moved to its upright position. At this time the oxygen lance is in standby position while refractory coating material is forced through the coating lance and outwardly of its nozzle to coat various areas of the vessel lining. Thereafter, the coating lance is withdrawn from the vessel and the oxygen lance is inserted and the refining process is begun. At this time, the coating lance is held in standby position.
