Abstract
A metallurgical vessel has releasably coupled, semicylindrical upper and lower sections arranged such that the axis of revolution of one section lies in a plane normal relative to the rotational axis of the other. The dimension of each section in the axial direction being the same as the dimension of the other section in the direction normal to the axis. The vessel is mounted for rotation about the axis of the lower section and an elongate charging mouth is formed in the upper section and is arranged with its major axis parallel to the axis of the lower section. A plurality of tuyeres extend through the lower section of the vessel and each tuyere includes a first tuyere pipe for injecting oxygen beneath the level of molten metal within the vessel, a second tuyere pipe disposed in surrounding relation to the oxygen pipe for injecting powdered materials entrained in a nonoxidizing gas and a third pipe surrounding the second pipe for injecting a hydrocarbon shielding fluid. The vessel is mounted for rotaton about the axis of the lower sections by means of a pair of rings.
