Abstract (en)

[origin: WO2012107143A1] The invention relates to a method for regulating a temperature (16), or a temperature profile (21), of a strand (1) by positioning a movable cooling nozzle (4) in a strand guide of a strand casting system. The aim of the invention is to optimize a regulating method by positioning a movable cooling nozzle (4) so that as precise a temperature control of the strand (1) as possible can be achieved, even under starkly different operational conditions in the strand casting system. Said aim is achieved by a method comprising the following method steps: determining at least one temperature value T (16) of the strand (1) in a direction that is transverse to the casting direction (9) of the strand (1); determining a control error e (14) by subtracting the temperature value T (16) from a target temperature TSoll (17) of the strand (1), that is, e = T Soll -T; calculating a control variable r (15) based on the control error e (14) and applying a control law; and positioning the cooling nozzle (4) in a direction that is transverse to the casting direction (9) of the strand (1) based on the control variable r (15) so that the control error e (14) is minimized.
