Abstract
An apparatus for starting the casting of a continuous casting system has a mold (2) and a strand guide (10; 10′) comprising drive and guide rollers (11, 12; 11′, 12′). Moreover, a dummy bar (22) that can be introduced into the mold (2) by the strand guide (10; 10′) and be withdrawn from said mold is provided. A safety device (20; 20′) for the dummy bar (22) has an element (25) that can be engaged, with form fit, with the dummy bar (22) and limiting the speed of the cold bar (22). It is thus guaranteed that a predetermined maximum strand speed can not be exceeded and that the dummy bar does not slide through.
Claims20
An arrangement for starting casting of a continuous casting system that has a mould and a strand guide comprising drive and guide rollers, the arrangement comprising:
