OPERATION METHOD FOR MECHANICALLY STIRRING CHROME-CONTAINING MOLTEN IRON |
摘要 |
A method for stirring chrome-containing molten iron comprises mechanically stirring chrome-containing molten iron contained in a refining vessel by the use of an impeller having a rotation axis in the vertical direction where the refining vessel is such that the horizontal cross section of the inner wall thereof is circular around the central axis of the vessel in the vertical direction and the impeller, as integrated with the axial rod covered with a refractory, rotates around the central axis of the axial rod, as the rotation axis thereof. The stirring mode is regularly or irregularly switched between a concentric stirring of the molten iron in a state where the rotation axis of the impeller is centered in the central axis of the vessel and an eccentric stirring of the molten iron in a state where the rotation axis of the impeller is decentered from the central axis of the vessel.
