PROBLEM TO BE SOLVED: To provide a refining method with which a proper refining reaction is occurred and even in the case the amount of generated gas by refining is small, the gas can be recovered as thermally reusable gas. SOLUTION: When the prescribed refining is performed by supplying oxygen into molten metal in the refining furnace, plastics are charged into the refining furnace, and the gas generated with the refining reaction together with the gas generated from the plastics, are recovered as the thermally reusable gas. |
