<p>Disclosed is a method for producing stainless steel, particularly high-grade steel containing chrome or chrome nickel, in a melting device comprising one or two or more containers (1, 2), each of which is operated by electric arcing or oxygen top blowing. The inventive method comprises the following steps: (a) iron-containing liquid and/or solid charges and alloy carriers (1) are charged; (b) the charge is melted by arcing; (c) the molten mass is refined by oxygen top blowing; and (d) the chrome-containing slag is reduced. Said method allows timing for a great chrome reduction of the slag (19) as the blowing time (3) is equal to or less than the total duration of the steps required for reducing the slag by arcing (4), tapping (5), charging liquid and/or solid charges and alloy carriers (1), and arc melting (2).</p> |
