摘要：Disclosed is a method for producing stainless steel, particularly high-gradesteel containing chrome or chrome nickel, in a melting device comprising one or two ormore 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/orsolid charges and alloy carriers (1) are charged; (b) the charge is melted by arcing; (c) themolten mass is refined by oxygen top blowing; and (d) the chrome-containing slag isreduced. Said method allows timing for a great chrome reduction of the slag (19) as theblowing time (3) is equal to or less than the total duration of the steps required forreducing the slag by arcing (4), tapping (5), charging liquid and/or solid charges and alloycarriers (1), and arc melting (2).
