A dummy bar for use in a continuous casting operation is comprised of a series of parts which are linked together to pivot about parallel axes. Each joint between adjacent parts includes an end of one of the parts and a pivoting axle mounting the other adjacent part pivotally on the one part. A peg or pin is affixed to either the end of the one part or the pivoting axle and is received in a closed seat of either the pivoting axle or the end of the one part with sufficient play to permit a limited angular movement between the parts transversely of the pivoting axis. |
