Abstract
An open topped vessel for converting molten ferrous metal to steel is pivotal about a horizontal axis and has bottom tuyeres for blowing oxygen or other gases upwardly through molten metal contained therein. An enclosure at least partially surrounds the vessel and cooperates with a smoke hood to prevent the escape of pollutants when the vessel is in a generally vertical gas blowing position. The vessel is pivotable about a horizontal axis to position its open top adjacent an access door in the enclosure whereby the vessel may be charged with hot metal from a ladle or with scrap from a charging chute. A pair of bumpers are positioned adjacent the access door support beams to prevent damage thereto by the charging apparatus.
