Abstract (en)
[origin: WO2012080368A1] The invention relates to a rolling mill for producing metal strips, preferably steel for tubes and/or thin strip, in which the temperature control can be influenced between the finishing stands Fi and Fi+1 using a rapid heating device (induction heater), characterized in that the distance between the stands Fi and Fi+1, between which a rapid heating device is arranged, is 5 to 25 m, and in addition to an induction heater, a roller flattening unit (for example, roller leveller 14) and/or shears 8 and/or a driving roller pair 12 and/or a descaling sprayer 15 are arranged as additional units between the two stands. The roll stand Fi and/or regions in front of the roll stand Fi further comprise actuators for influencing the strip warping and/or strip turn-up/ -down (ski) at the strip head.
