Method for processing material to be rolled on a rolling line, and rolling line

A method for rolling materials to be processed in an advancing direction in a rolling line wherein

• the rolling line includes at least one rolling section, each rolling section having at least two rolling stands arranged in the advancing direction, each roll stand having at least one roll configured and operable for enabling movement of the materials in the advancing direction;
• a separate respective drive with a rotational speed regulator for the at least one roll of each roll stand for moving the materials in the advancing direction;
• the method comprising:
• determining a first point in time at which the real load moment is imposed on the drive of the first roll stand by reference to a measurement of a rolling force at the first roll stand;
• and
• at a second point in time, which depends on the first time point at which the real load moment caused by the materials moving in the advancing direction is imposed on the drive of the first roll stand in the rolling section, feeding a supplementary value, which is a function of an expected real load moment, to the rotational speed regulator of each drive, wherein the feeding of the supplementary value is simultaneous with the rotational speed regulator of the drive of the first roll stand and with the rotational speed regulators of the drives of the subsequent roll stands in a same rolling section such that the supplementary value regulates the rotational speed regulators to regulate the rotational speeds of the drives.

A rolling line for the processing of materials to be rolled, the rolling line comprising:

• at least one rolling section having at least two roll stands, and each roll stand having at least one roll;
• and
• a separate drive with a rotational speed regulator configured for driving and regulating the at least one roll of each roll stand;
• and
• a control/regulation unit configured and operable for controlling the speed regulators for the rolls such that at a first point in time at which a real load moment caused by the materials moving in an advancing direction is imposed on the drive of the first roll stand in the rolling section determined by material tracking of the material being rolled by one or more hot metal detectors, and at a second point in time which depends on the first time point, feeding a supplementary value, which is a function of an expected real load moment, to the rotational speed regulator of each drive, wherein the feeding of the supplementary value is simultaneous with the rotational speed regulator of the drive of the first roll stand and with the rotational speed regulators of the drives of the subsequent roll stands in a same rolling section such that the supplementary value regulates the rotational speed regulators to regulate the rotation speeds of the drives.

A rolling line for the processing of materials to be rolled, the rolling line comprising:

• at least one rolling section having at least two roll stands, and each roll stand having at least one roll;
• and
• a separate drive with a rotational speed regulator configured for driving and regulating the at least one roll of each roll stand;
• and
• a control/regulation unit configured and operable for controlling the speed regulators for the rolls such that at a first point in time at which a real load moment caused by the materials moving in an advancing direction is imposed on the drive of the first roll stand in the rolling section determined by material tracking of the material being rolled by a measurement device for measuring the rolling force on the first roll stand, at a second point in time which depends on the first time point, feeding a supplementary value, which is a function of an expected real load moment, to the rotational speed regulator of each drive, wherein the feeding of the supplementary value is simultaneous with the rotational speed regulator of the drive of the first roll stand and with the rotational speed regulators of the drives of the subsequent roll stands in a same rolling section such that the supplementary value regulates the rotational speed regulators to regulate the rotation speeds of the drives.
