Abstract

PURPOSE:To perform formation of a reinforcing rib simultaneously with the formation of the body of a channel and to improve productivity by providing a groove for forming the reinforcing rib to either of upper and lower rolls of a series of mills forming the channel. CONSTITUTION:In 2 passes K10, K11 out of 5 passes of BD mills 3, passes K9, K10, K7, K6, K5 of roughing mills 4, passes K4, K3, K2 of intermediate mills 5 and further pass K1 of finish mills 6, a channel-shaped body is formed by the passes of the upper, lower forming rolls and a channel C with a reinforcing rib is formed by the reinforcing rib forming groove provided to the respective upper rolls. A channel D with reinforcing rib provided with a reinforcing rib 2'' on the outer side surface of the web 1''A of a channel-shaped body 1'' is formed simultaneously with the body ''1 by the reinforcing rib forming groove provided on the respective lower roll sides.
