熱延ランナウトテーブル通板解析 : ROT通板不安定現象に対する実験的検討(機械力学,計測,自動制御)

Abstract

In the Hot-Rolling process, when a thin strip runs on the Run-Out-Table (ROT) at high speed in the state of non-tension (a head or a tail of a strip), the defects resulting from the running instability pose a chronic problem. Moreover, for the running unstable phenomenon, the maximum line speed has been restrained, and has also become a prevention factor of productivity. In order to solve and improve this problem, various methods have been proposed from the former, but it has not eradicated completely. In this paper, we propose two types of the experimental method to simulate the ROT running phenomenon in a laboratory. The ROT strip running unstability theorem was proven by using them experimentally. By utilizing them, the improvement cost and term become cheaper and shorter.
