  • Process and apparatus for separating a suspension bar from an electrode
    Patent number: 4577401
    Abstract: Process and apparatus for separating a suspension bar (14) from an electrode (11) that is vertically suspended by this bar and that comprises, besides this bar, an electrolytic plate (12) and one or several suspension loops (13) fastened to the plate, the suspension bar extending through these loops.The suspension bar (14) is first relieved of the weight of the plate (12) by bringing the electrode (11) in a horizontal position in which its plate (12) is caused to rest on a support (34 or 34').The position of the bar (14) is then changed with regard to the position of the plate (12) by moving the support (34 or 34') with the plate (12) in a direction parallel to the longitudinal axis of the bar (14) while retaining the latter.

  • Manufacture of copper wire rod
    Patent number: 3942582
    Abstract: A process for the manufacture of copper wire rod, in which liquid copper is cast in a continuous casting machine provided with an inclined straight moulding cavity to produce a continuous bar of copper, comprising guiding said bar as it leaves the casting device towards a horizontal rolling machine known "per se" along a curved path, the maximum curvature of the curved path being less than 0.25 m.sup.-.sup.1 thus preventing the formation of cracks in the hot bar, and converting the said bar into wire rod in the said rolling machine.
