Plant and method for reducing a deviation from an setpoint tensile strength and a setpoint yield strength / offset yield strength of rolling stock produced with the plant

Abstract

The invention discloses a plant and a method for reducing a deviation from a setpoint tensile strength (Rm_soll) and a setpoint yield strength / offset yield strength (Re_soll / Rp0.2_soll, Rt0.5_soll, etc.) of rolling stock (4) produced with the plant (1), which comprises at least one hot rolling train (2) and at least one roller straightening machine (3) downstream of the hot rolling train (2), in particular steel sheets, single-layer or multi-layer rolling slabs or rolling ingots of the same steel grade which have been fed from this plant (1) and the respective steel alloy of which deviates, in at least one alloy element, in the actual chemical composition from the intended chemical composition of this steel grade due to the production process.
