1. , the dummy bar that comes out the casting path along a bending from crystallizer of the initiating terminal of a kind of crystallizer that is used for sealing continuous casting machine and guiding strand, one end of this dummy bar has a bar head that connects the initiating terminal of strand, the afterbody of the other end is by constituting the throwing roller guiding strand of a conticaster part, also have one between bar head and tail portion, to comprise near first flex section of afterbody and second shaft that is actually the rigid element of rigidity of close bar head, it is characterized in that shaft comprises:

  • A public backbone, this backbone are positioned on the operation intrados of shaft, and have determined the inner bend radius of dummy bar on described crooked casting path;

    A series of joint pieces are positioned at the operation extrados of shaft, and headtotail ground is arranged, and the outer surface of one side and backbone joins, and these joint pieces have determined the outside sweep radius of dummy bar on the described crooked path of casting;

    A plurality of cushion blocks, between the joint piece and its quantity with to save the piece number corresponding, when being arranged in dummy bar and being in curved shape corresponding to described crooked casting path, cushion block can constitute the neighbouring relations that a kind of oneself supports between envoy'"'"'s piece, and cushion block can be used to prevent that dummy bar is towards the direction bending of leaving backbone, backbone in first flex section of dummy bar is flexible more much better in fact than the backbone in second rigid element, and relevant joint piece is used to make first flex section to bend to have than the little bending radius of described casting crooked route radius.
