<p>PROBLEM TO BE SOLVED: To provide a low Ti steel suitable to a bearing for audio equipment with which the Ti concentration inevitably mixed into molten steel from a refractory, scrap and slag in an electric furnace in a melting process of steel is reduced as less as possible. SOLUTION: In this method for producing the low Ti steel, a process for melting the scrap by adding slag-making agent into the electric furnace, a process for slag-off after tapping molten steel into a ladle under the state of leaving the produced slag and a process for reduction-refining the molten steel in the ladle are alternately repeated at least each two times.</p> |
