Abstract

PURPOSE: To make the rolling stand installed in front of the rolling mill fully display the function as the rolling mill, to improve the productivity, and to improve the shape of the product, by installing a rolling stand comprising a couple of rolling rolls driven at respectively different circumferential speeds, on the feed-in side of a rolling mill consisting of one or more rolling stands.
CONSTITUTION: A differential rolling stand 1, comprising a couple of rolling rolls driven at respectively different circumferential speeds, is installed on the feed-in side of a rolling mill 2 consisting of three rolling stands. Thus arranged rolling apparatus performs economically the cold rolling process in high productivities by distributing the draft percentage as follows; for example, 5% for the differential rolling stand 1, 45 or 40% for No.1 stand, 35 or 40% for No.2 stand, and 10% for No.3 stand; hereby, as a result of shape and profile correcting effects of the differential rolling work, the product of high quality is obtained.
