Tandem rolling mill facility and rolling method using the same

摘要

In a tandem rolling mill facility and a rolling method using the tandem rolling mill facility, stable rolling is performed with suppressing deflection of working rolls 1 and without fluctuation of working roll bearing boxes 4. Axes of working rolls 1 are offset toward a side opposite to a side of larger tension between tensions acting on a rolled material 10 at an inlet side and an outlet side with respect to axes of intermediate rolls 2, and a hydraulic cylinder 11 for pushing a working roll bearing box 4 toward the same side as the offset direction is contained in a block 8. <IMAGE>
