Abstract

PURPOSE:To make it possile to easily control the tension, by adjusting the roll gap, etc. by the deviation amount of tension which has been derived from the sagging amount of the rolled material between the stands. CONSTITUTION:The sagging amount y between the stands is derived from the distance x between the sagging amount detector 2 and the rolled material S, and the distance z between the pass line 8 and the sagging amount detector 2, as the expression y=z-x. And the tension T between the stands is derived in the tension operation device 3, as the expression T=f(H.W.L.E.rho.y). In this case, H, W, L, E and rho mean thickness of plate, width of plate, distance between stands, Young's modulus and density. After that, the tension between the stands is controlled to the amied value by performing the operation 5 of the roll rotary speed variation amount by the deviation to the aimed tension, and controlling 6 the roll rotational frequency.
