AUTOMATIC START METHOD AND DEVICE FOR CONTINUOUS CASTING SYSTEMS

摘要

The invention relates to an automatic start method for continuous casting systems, preferably for strand thicknesses of 10 -150 mm and widths of up to 3.500 mm by regulating the casting level and by means of a closure system consisting of a slider system or a stopper system. In order to automatically start the continuous casting system, the following process data is detected: the temperature of the steel at the end of the treatment thereof in the secondary metallurgic range, T.LF (11); the heating-up time of the distribut or before casting begins, t.T0,5 (5.1); the inner distributor temperature after the distributor has been pre-heated, W.T (14), T.T (4); the weight of the steel in the distributor at the moment when the distributor is opened for casting to begin; the time required to fill the permanent mold, the time between the moment the permanent mold is opened and the strand (15) is removed; formation of a functional context for the product of T.LF (11), t.T0,5 (5.1), W.T (14), for example; formation of the functional relationshi p between filling time (15) and the product from ((11) (5.1) (14)); establishment of the desired filling time (15) for all successive castings a nd determination of the weight of the steel in the distributor equivalent to th e desired filling time when the temperature of the steel T.LF (11) is set in a n uncontrolled manner; pre-heating time of the distributor t.T (5) and distributor temperature T.T (4) directly before the kettle is opened in orde r to fill the distributor.
