METHOD FOR PRODUCING ROLLING STOCK BY MEANS OF A COMBINED CONTINUOUS CASTING AND ROLLING SYSTEM, CONTROL DEVICE FOR A COMBINED CONTINUOUS CASTING AND ROLLING SYSTEM, AND COMBINED CONTINUOUS CASTING AND ROLLING SYSTEM.
METHOD FOR PRODUCING ROLLING STOCK BY MEANS OF A COMBINED CONTINUOUS CASTING AND ROLLING SYSTEM, CONTROL DEVICE FOR A COMBINED CONTINUOUS CASTING AND ROLLING SYSTEM, AND COMBINED CONTINUOUS CASTING AND ROLLING SYSTEM.
The invention relates to a combined continuous casting and rolling system, to a control device for a combined continuous casting and rolling system, and to a method for producing rolling stock (B), in particular metal strip, by means of a combined continuous casting and rolling system, comprising a casting device (1, 1') for casting metal and a roll train (2) comprising at least one roll stand for hot forming the rolling stock (B), wherein the combined continuous casting and rolling system is operated such that the rolling stock (B) extends continuously between the casting device (1, 1') and the roll train (2), wherein rolling stock is continually supplied to the roll train (2), wherein a target thickness progression according to which the roll train (2) rolls the rolling stock (B) is predetermined for the roll train (2). Because the thickness progression has at least two different target thicknesses for different sections in the longitudinal direction of the rolling stock (B) and the thickness progression is designed such that the first and/or the second target thicknesses are set at least twice, it is possible for longitudinally profiled rolling stock to be produced considerably more inexpensively than with conventional processes. To this end, the combined continuous casting and rolling system is operated such that an infeed rate (V) of the rolling stock (B) into the roll stand is set to less than 7 metres/second, in particular less than 5 metres/second, in particular between 1 metre/second and 4 metres/second.
