The invention relates to a method for calculating a pass plan of a stable rolling process when rolling a metal strip in a rolling mill and to a corresponding computer program product. In this case, the offset is varied until the calculated target horizontal force meets a predetermined limit criterion. It means that the roller set and the rolling process are stable at the moment when the limit standard is met. In the event that only the iteration of the bias of the working rolls does not cause compliance with a limit criterion, the invention proposes that the pulling force acting on the rolling stock on the entry side and/or on the exit side of the rolling stand is subsequently iteratively varied while keeping the bias constant until the calculated target horizontal force meets the limit criterion. 本发明涉及用于在轧机中轧制金属带时计算稳定的轧制进程的道次计划的方法以及相应的计算机程序产品。在此，改变偏置量，直到计算出的目标水平力满足预设的极限标准。满足极限标准意味着：轧辊组和轧制进程此时是稳定的。在仅工作轧辊的偏置的迭代不引起遵守极限标准的情况下，本发明提出：随后，在保持偏置恒定的情况下迭代地改变作用于轧制机架的进入侧上的和/或离开侧上的轧制物上的拉力，直至计算的目标水平力满足极限标准。
