A Steckel mill has a reversing unit for rolling a rolled product and winding furnaces arranged on the entrance side and exit side of the reversing unit. When rolling the rolled product in a region of a head of the rolled product, a target thickness of the rolled product is ignored, while measuring a current thickness and/or a hardness of the rolled product and comparing this with a setpoint value. One the measured variable reaches or is below the setpoint value, the reversing unit is operated with a view to achieving the target thickness of the rolled product. The Steckel mill is operated to allow for rolling of a cold, non-rollable piece of the rolled product, so that malfunctions are avoided and the usable part of the rolled product is as large as possible.

A control method for a roll press device, an electronic device, and a storage medium are provided. A first average thickness is obtained. A first deviation value between the first average thickness and a preset target thickness is determined. A master-cylinder adjustment value of the at least one master cylinder is determined according to the first deviation value, in response to the first deviation value being greater than a first preset deviation-value. The at least one master cylinder is adjusted according to the master-cylinder adjustment value, in response to the master-cylinder adjustment value being greater than a first threshold. A second average thickness is obtained in response to the master-cylinder adjustment value being less than or equal to the first threshold. A bending-cylinder adjustment value is determined according to the second average thickness. The at least one bending cylinder is adjusted according to the bending-cylinder adjustment value.

A preset value of at least one setting value in a shape control actuator included in a cold rolling mill is calculated by a presetting method. In the presetting method, an MC actual value for cold rolling performed in the past is calculated. In the presetting method, an MC target value in a rolled stock to be manufactured by the cold rolling to be performed next is calculated based on the MC actual value. In the presetting method, the setting value is selected so that a difference between an MC prediction value in the cold rolling to be performed next and the MC target value is minimized, and the selected setting value is set as the preset value.
