Abstract (en)
[origin: WO2005099923A1] During the production of steel, a conversion model (10) is used for the cooling line (5). Said model is used to calculate the phase fractions (Pi), in addition to the temperature (T) of the steel, along the steel strip in real time. A regulating system, which maintains the phase fractions (Pi) of a steel strip that is wound onto a reeling device (12) at a constant level, is implemented. The method comprises the following steps: in a first step, the degree of conversion, for multi-phase steel e.g. the ferrite fraction, is determined from data obtained from the primary data (P) of the steel strip. In a second step, when the strip enters the cooling line (5), one or more parameters of the cooling strategy, i.e. control values (S), are adapted online in such a way that the ferrite content of the cooled steel on the reeling device (12) is maintained at a constant level.
