<p>PROBLEM TO BE SOLVED: To provide a method, by which molten nickel-containing steel can be obtd. at lower cost than the conventional method even in the case of using metal nickel as the nickel source. SOLUTION: At the time of melting the nickel-containing steel by using the metal nickel as the nickel source for adding into molten steel, the plate-like metal nickel produced with an electrolysis is beforehand charged into a ladle, and the molten steel after executing decarburize-refining in a refining vessel, is tapped into the ladle to dissolve the metal nickel in the molten steel.</p> |
