摘要： PROBLEM TO BE SOLVED: To provide a metal refining furnace which can be used for an electric furnace or a converter by simply changing over the use and which treats exhaust gas desirably. SOLUTION: Perpendicularly movable electrodes 10 and a first shifting means 15 for shifting between the respective positions of a furnace body upper part and a side part thereof while supporting the electrodes are arranged at the portion near the metal refining furnace 1 usable as electric furnace. On the other hand, a short flue 20 for gas exhaust and a second shifting means 25 for shifting between the respective positions of the furnace body upper part and the side part thereof while supporting the short flue are arranged at the other portion near the same furnace body. Then, when the above short flue 20 is shifted to the furnace body upper part, at the position near the lower flowing end part of the short flue 20, a flue 30 which is freely separated from/ connected with the short flue 20 and can exhaust the gas, is fixedly disposed.

摘要： PROBLEM TO BE SOLVED: To enable the shut-off of heat and the cooling of a furnace body at the time of directly fitting a trunnion shaft to the furnace body. SOLUTION: At the portion for fitting the trunnion shaft 16 to the iron shell 18 of the furnace body in a converter, a block structure 10 is formed and the base end part of the trunnion shaft 16 is separated from the iron shell 18. The trunnion shaft 16 is interposed between an upper stiffening ring 11 and a lower stiffening ring 12 and held with a welded part 15 between an inner reinforcing plate 13 and an outer reinforcing plate 14. On the surface of the iron shell 18, a water cooling pipe 19 is fitted to cool the iron shell 18.

摘要： 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.
