Abstract

PURPOSE: To control inter-stand tension to target tension with high accuracy by controlling the inter-stand tension by tension which has been derived from a deflection of a prescribed stand by taking the influence of a rolling load into consideration and deriving the inter-stand tension of a material to be rolled with high accuracy.
CONSTITUTION: When a material to be rolled 12 is being rolled by a continuous rolling mill, a deflection of a prescribed stand H4 before and after the stand concerned H4 bites the material to be rolled 12 is detected 16, based on a high fixed position of the stand concerned H4 as a reference. Also, a rolling load of the stand H4 is detected 14, and from these detected deflection and detected rolling load, inter-stand tension of the upstream side or the downstream side of the stand H4 is operated and derived by a computing element 30. Subsequently, the tension is controlled by controlling the speed of revolution of a roller of the continuous rolling mill concerned so that the derived inter-stand tension becomes target tension. As a result, rolling is stabilized, the dimension accuracy of the material to be rolled 12 becomes satisfactory, and also, the yield can be improved.
