Patent number: 8402802Abstract: A conveying device includes a plurality of conveying rollers supported in parallel at predetermined intervals, and conveys a workpiece to a heat-retaining/heating furnace from a rolling mill by the conveying rollers. The conveying device includes an impact prediction data collecting unit and a control unit. The impact prediction data collecting unit acquires data on the upstream of the heat-retaining/heating furnace. The data is used to predict the magnitude of an impact applied to rollers in the furnace, which are positioned in the heat-retaining/heating furnace, of the conveying rollers by the workpiece. The control unit predicts the magnitude of an impact from the data, which is acquired by the impact prediction data collecting unit, and adjusts the conveying speed of the workpiece in the heat-retaining/heating furnace according to the magnitude of the impact.Type: GrantFiled: January 15, 2009Date of Patent: March 26, 2013Assignees: IHI Metaltech Co., Ltd, IHI CorporationInventors: Masahiro Kuchi, Hajime Ishii, Hisashi Honjou

Patent number: 6065319Abstract: Each of a pair of rolls has a barrel with different diameters axially of the barrel such that sum of the diameters of the barrels is substantially constant and that each of the rolls is bilaterally symmetrical. The rolls themselves have an ability to control workpiece profile and have at least one substantially parallel center portion.Type: GrantFiled: September 4, 1997Date of Patent: May 23, 2000Assignee: Ishikawajima-Harima Jukogyo Kabushiki KaishaInventors: Masao Mikami, Masahiro Kuchi, Sadahiko Shinya, Takayuki Iwasaki, Takashi Nishii

Patent number: 5950478Abstract: There are provided an even number of paired roll-shift type rolling mills 12a, 12b and a controller 16 for controlling the rolling mills 12a, 12b. Each of upper and lower work rolls 13 of each of the roll-shift type rolling mills has a predetermined crown curve and has a roll shifting mechanism 14 for axially shifting the upper and lower work rolls relative to each other. The controller 16 determines a shift amount of each rolling mill in order to obtain a predetermined cross section shape of a steel plate, shifts the work rolls of the rolling mill on the upstream side paired every rolling coil to thereby disperse wear on the roll surface, and moves the work rolls of the rolling mill on the downstream side of the pair in a predetermined direction by the same distance, thereby canceling the change in the cross section shape of the plate caused by the shifting operation for the wear dispersion.Type: GrantFiled: May 26, 1998Date of Patent: September 14, 1999Assignee: Ishikawajima-Harima Heavy Industries Co., Ltd.Inventors: Masayoshi Sato, Kazuyuki Sato, Hisashi Honjou, Masahiro Kuchi
