<p>PURPOSE:To surely prevent necking by measuring the position of the transformation temp. of the present strip in the direction of line with plural transformation rate sensors and predicting the generating position of necking based on that result. CONSTITUTION:The plural transformation rate sensors 4 are arranged on run out tables 3 to measure the position of transformation temp. of the present strip 5 and the position of transformation temp. of the strip 5 can be measured with these transformation temp. rate sensors 4. And, because the generating position of necking is predicted based on the position in the direction of rolling process line, the generating position of necking can be predicted with high accuracy. Therefore, the generation of necking can be surely prevented.</p> |
