Patent number: 6397650Abstract: The present invention relates to a roll stand for bar and wire rod rolling mill, capable of being applied to various sizes of bars and wire rods by a small number of housing block sets, permitting maintenance work therefor to be carried out easily, and having characteristics in the housing thereof. The roll stand for bar and wire rod rolling mill according to the present invention is characterized in that the housing is divided into two, i.e. a roll block and a driving block by a plane including a position in which a driving gear and a driven gear are meshed with each other or a position in the vicinity of this position, whereby the number of housing block sets to be prepared is reduced. This enables the housing manufacturing cost to be lowered, and the replacement of a roll to be carried out efficiently.Type: GrantFiled: December 18, 2000Date of Patent: June 4, 2002Assignees: Kawasaki Steel Corporation, Sumitomo Heavy Industries, Ltd.Inventors: Tomoyasu Sakurai, Takao Ogawa, Ryo Takeda, Yoshihiro Shinkai, Shigeharu Ochi, Takeshi Tange
