<p><P>PROBLEM TO BE SOLVED: To provide a method of rolling a weld zone by which the efficiency of rolling is improved by suppressing the lowering of a rolling speed of the weld zone having lateral bend when continuously rolling a plurality of steel strips to be connected by performing welding successively. <P>SOLUTION: The weld zone between mutual steel strips is detected and its travelling position is tracked (a1, a2). The amount of the lateral bend in the weld zone is detected and the rolling speed of the weld zone is selected in accordance with the amount of the lateral bend (a3-a5). When the weld zone reaches a prescribed position before rolling, the rolling speed is adjusted so as to be reduced to the rolling speed which is selected in accordance with the amount of the lateral bend (a6, a7). When the weld zone reaches a prescribed position after it is rolled, the rolling speed is returned to that before the adjustment (a8, a9). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
