Abstract: PROBLEM TO BE SOLVED: To enable execution of an advantageous operation by bearing melting equipment so that it is rotatable only at a first rotational angle around a first point of rotation and that it is rotatable only at a second rotational angle around a second point of rotation. SOLUTION: A first electrode 5 and a reaction medium supply conduit 12 are put in and taken out through the same guide port of a cover 4 in time sequence during an operation. Melting equipment is made rotatable only at a first prescribed rotational angle β around a first point 19 of rotation located just below the bottoms of the lower parts of reaction vessels 1 and 2. Besides, it is so borne as to be rotatable only at a second prescribed rotational angle αaround a second point 20 of rotation located in the sphere of the centers of supply lines 5 and 12 which can be put in and taken out, within the extent of the cover 4 in a hood 3 of the melting equipment. According to this constitution, two melting equipment can be operated simultaneously and it is possible to make one conduct a converter operation and the other an arc operation.
