Abstract

1440015 Continuous casting VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWEKKE-ALPINE MONTAN AG 29 June 1973 [12 Jan 1973] 31103/73 Heading B3F A flexible steel tape 11, e.g. 3-20 mm. thick, is connectible to a dummy bar head 12, for use as a dummy bar, and at least one of its margins is enclosed by a guide 10, laterally of the strand guide which has rolls 2, 3 on supports 21, 23. Spring steel compositions for the tape dummy are given. Instead of a simple tape a tape woven from wires or strips may be used. The hooked head 12 is releasably connected to the tape dummy and may be exchanged when the mould is exchanged. The head is separable from the strand by a rotary movement as described in Specification 1,208,236. The tape dummy 11 is withdrawn from a vertical, reciprocated mould downwardly in an arcuate apron of rolls 2, 3 and is backed by the inner curve, adjustable rolls 2. It may continue in the same curve, rising above the horizontal end section of the apron, drawn by three bending rolls, Fig. 1 (not shown), of a reeling device which also has a pivoted arcuate guide. After initial withdrawal by the tape 11, the strand is engaged by withdrawal rolls in the horizontal end section and passed to rollers which both shape and withdraw it. The reeling device may be below or to the side of the apron. In Fig. 3 the reversible drive of a coiler 24 for the tape 11 is such as to cause straightening or bending of the tape to draw or push it through a straight run of the guide 10 and an arcuate portion 10<SP>1</SP> (adjacent to pairs 26 and 27 of grooved, shaping and withdrawing rollers and a roller table 9 at the end of the apron) when initially withdrawing or inserting the tape 11 and head 12.
