Abstract (en)

[origin: WO9422619A1] A method for forming a metal sheath (2) on an elongate core (1) having a different metallurgical composition from that of said sheath (2). According to the method, the core (1) is moved through a casting mould (10) by imparting a continuous vertical oscillatory motion combined with a vertical downward movement of the core (1), a molten filler metal (5) is cast in the mould (5) and covered with electrically conductive slag (7), the electrically conductive slag (7) is heated to a temperature of over 1450 DEG C, said electrically conductive slag (7) is rotated about the core (1), and the lower portion of the mould (10) is cooled to solidify the filler metal (5). A device for carrying out the method is also disclosed.
