CONTINUOUS ROLLING MILL

摘要

PURPOSE:To reduce the size of a continuous rolling mill disposed continuously with plural rolling mills and to permit easy rolling by providing a different- speed rolling mill to the final stand of said continuous rolling mill and enabling rolling satisfying required draft under a low rolling force. CONSTITUTION:The 1st stand of the continuous rolling mill is constant velocity rolling of an ordinary type and the final 2nd stand is constituted of the different velocity rolling mill of which the ratio between the sheet thickness on the inlet side of the rolling mill and the sheet thickness on the outlet side thereof is approximately equal to the peripheral velocity ratio of upper and lower work rolls 1, 2 and which rolls the material in a manner as to make the forward tension larger than the backward tension. The required draft is thus taken under the low rolling force with the different velocity rolling mill and the stable rolling is made possible.
