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 defect resulting from the running instability poses a chronic problem. Moreover, for the running unstable phenomenon, the maximum line speed is restrained, and has also become a prevention factor of productivity. In order to solve this problem, various methods are proposed from the former, but it has come to eradicate completely. In this paper, we describe the equation of motion of the strip which runs on the ROT at the first. In the next, we propose the equivalence principle (eigenvalue problem) of the ROT running unstable phenomenon and the buckling phenomenon.
