<p>PURPOSE:To measure a correct tension of the material to be rolled by correcting the measuring value according to the elongation of a housing to the rolling load in case of measurement with the horizontal load acting between the two stands thereof. CONSTITUTION:The material 5 to be rolled is rolled in order with stands 1, 2 of a continuous rolling mill with multistand. A load detector 6 and screw jack 7 are provided respectively to housing 1a, 2a between stands 1, 2 so as to avoid looseness. When a tension T is motioned between both stands via the material 5 the housing 1a, 2a are inclined in the directions x, x', the load against the detector 6 varies and the signal proportional to the tension is detected. However the housing 1a is elongated to the direction (y) with the operation of the rolling load F1 and the center of the detector 6 varies to delta1 as well. Now, the difference G of the elongations of two stands is found from the rolling load applied on both stands and mill constant, a horizontal component force T' against the measured value Ts of the detector 6 is founded from the distance L0 which is upto the contact face of G and the detector 6 and the tension measuring error base on the variation in rolling load is corrected.</p> |
