The invention discloses a control method for preventing a tension measuring roller from slipping relative to a continuous rolling strip. The method comprises that correlation coefficients are measured in advance; after a rolling mill unit begins to thread the strip, a system determines whether slipping exists between the strip and the tension measuring roller in real time through a critical condition discriminant; when the critical condition discriminant is not met, an electromagnetic clutch keeps a closed state, and the tension measuring roller is transmitted through a motor directly; when the critical condition discriminant is met, the electromagnetic clutch is separated, and the tension measuring roller is transmitted through the strip; when the action tension value reaches or exceeds the preset tension value, the system continues to increase the tension value continuously if determining that slipping still exists, till the system determines slipping is absent to separate the electromagnetic clutch, and the tension measuring roller is transmitted by the strip. By means of the control method, the tension measuring roller can be transformed into an inertia roller at the appropriate time and overcome slip relative to the strip, the lower surface of the strip can be effectively protected, and the tension measuring roller service life can be prolonged.
