1.绪言日本室兰厂小型轧钢车间使用无张力控制技术替代了粗轧和中间轧制机架的张力控制方法,从此,日本钢厂便改进并成功地发展了新的无张力控制技术,本文则是关于这项新技术的报告。 2.新的无张力控制技术的特点 (1)假定在轧制时,转矩臂是个常数,轧制转矩可用内转矩臂与轧制力的乘积来计 1. INTRODUCTION Japan’s small-scale rolling mill in Muroran uses tension-free control technology to replace the tension control method for roughing and intermediate rolling stands. Since then, Japanese mills have improved and successfully developed new tension-free control technologies. It is a report on this new technology. 2. The characteristics of the new tension-free control technology (1) Assuming that the torque arm is a constant during rolling, the rolling torque can be calculated as the product of the internal torque arm and the rolling force
