<p>PURPOSE:To improve the reaction efficiency by shifting as percolating refining agent and slag toward one direction and reverse direction by flow accompanied with rotating motion caused by a magnetic field of molten metal in a bending reaction vessel. CONSTITUTION:Rotating force is forced as acting the rotating magnetic field by a rotating magnetic field generator 5 in such as molten iron 3 held in the bending reaction vessel 2 (refractories). As a result, the rotating motion generated in the molten iron 3 is transmitted to the opposite side (left side in the attached drawing) of the apparatus 5 through the max. deep part corresponding to the bending part of the vessel 2, and whole molten iron is moved as rotating. Then, flux 4 for desulfurized agent is blown from the left side through an injection lance 6 together with a small quantity of carrier gas. The flux 4 is enclosed into the rotating motion of the molten iron and reacts in contact with the molten iron in the vessel 2, to execute the desulfurized reaction and to float up as slag 7. ?Then, the apparatus 5 is once stopped and at the time of acting the rotating magnetic field to the molten iron by the same apparatus 5' in the other side, the slag 7 is floated up on the molten iron at the apparatus 5' side while reacting in same manque, as described above. Such a process is executed one or more times, to refine.</p> |
