ABSTRACT:
Start-up head for continuous casting in the horizontal has a coupling member that will be embedded from three sides in molten metal, the coupling member has a hooklike portion having an undercut portion below a center line of the casting and having a point of curvature inflection, the undercut portion running from that point of inflection towards the center line along a circular path having a center of curvature above a horizontal plane that runs through the center line; a front end of the hooklike portion has a circular contour beginning from a point below the center line at a distance that is about the same distance the point of inflection has from the center line, the circular contour extending to the upper side of the member has a center of curvature above the first mentioned center of curvature but a larger distance from the center line; and the center for uncoupling the member from the casting is situated between the first and second centers of curvature.
