Patent number: 4003229Abstract: There is described a method for compensating tail end of rolling materials for rolling shaped steel sections in an optimum manner. According to this method, in a continuous tension free rolling operation of a shaped steel section comprising a flat section and a flange section through a plural number of roll stands, the operating speed of a first roll stand is reduced by a predetermined amount as compared with a second or succeeding roll stand when the crop at the tail end of the rolling material enters the first rolling unit, thereby to prevent overfeeding.Type: GrantFiled: March 26, 1975Date of Patent: January 18, 1977Assignees: Nippon Steel Corporation, Mitsubishi Electric CorporationInventors: Toshio Harada, Shinichi Nakamata, Shiro Araki, Koei Nakashima, Hironori Kawasaki, Kazuo Watanabe, Keiichi Miura
