Abstract (en)
[origin: EP0786531A1] The method concerns melting of metals (in particular, steels and alloys based on nickel and cobalt) to produce a continuous bar, by gradual melting of at least one consumable electrode (16) in an electrically conductive slag bath (18) held in a short casting die (20). The electrode melting rate in kg/hr is set to a value equal to 1.5 to 30 times the bar diameter in mm, with the ratio of the cross-sectional area of one or more electrodes to the cross-sectional area of the bar chosen greater than 0.5. The apparatus used for implementation of the method includes at least one consumable electrode (16) and a continuous casting die (20) joined to a current source (10). The die is provided with an exit section determining the bar cross-section, and a broadened upper section (22) for a slag bath (18). At least one current-carrying element (42) is built into the die wall (28).
