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. An enclosure at least partially surrounds the vessel and has a top opening to permit a primary smoke hood to prevent the escape of pollutants when the vessel is in its vertical position. An auxiliary hood is disposed above an access door and is provided in the enclosure laterally of the vessel tilt axis. An elevatable auxiliary smoke hood is disposed in surrounding relation to the smoke hood for sealing the top opening.
