Device for applying injection lances or burners to the side walls of electric furnaces for steelmaking

摘要

A device for applying injection lances or burners to the side walls of electric furnaces for steelmaking, comprising a supporting body (2) which is associable with the side wall (3) of a furnace (4) in order to close an opening (5) which is predefined in the wall. The supporting body is provided with a passage (6) for the delivery end of an injection lance (7) or of a burner. The passage is inclined downward in the direction of injection of the lance or burner that it is designed to accommodate and its length is adapted to place its outlet (9) proximate to the inner face (10) of the layer of refractory material (11) that covers the lower portion of the side walls (3) of the furnace (4).
