STEEL CONVERSION APPARATUS

摘要

An open topped vessel for converting molten ferrous metal to steel is pivotable about a horizontal axis and has bottom tuyeres which permit the blowing of oxygen or other gases upwardly through the molten metal. An enclosure at least partially surrounds the vessel and co-operates with a smoke hood to prevent the escape of pollutants when the vessel is in its vertical position. Suction means is coupled to the hood for creating an in-draft at a closable access opening to prevent the release of pollutants when the vessel is pivoted to place its open top adjacent the access opening for receiving a charge.
