ABSTRACT:
A continuous casting machine for billets and blooms has a curved mold which is followed by a curved cooling zone and a straightener. A dummy bar for the casting machine has a length at least equal to the distance between the mold and the straightener. The dummy bar has a rigid portion and a flexible portion which are pivotally connected with one another. The rigid portion, which is curved and has a radius equal to the casting radius, includes a dummy bar head. The flexible portion is made up essentially of pivotally connected, curved links having radii equal to the casting radius. The flexible portion is designed such that it can assume radii equal to or less than the casting radius. When the dummy bar is in position for casting, the flexible portion assumes the casting radius and the dummy bar conforms to the curvature of the casting machine. Since the rigid portion of the dummy bar need not be supported in this position, less support structure between the mold and the straightener is required than for a dummy bar which is flexible in its entirety. When the dummy bar is not in use, it is stored with the flexible portion thereof bent to a radius much smaller than the casting radius. The dummy bar thus takes up less space in storage than a dummy bar which conforms to the curvature of the casting machine and is rigid in its entirety.
