その中央に雄ねじ部材１０が螺入されている。The drive/support mechanism 5 includes a male threaded member 10 and a guide rail member 11 arranged parallel to the roll center axis L2, and a motor 12 that drives the male threaded member 10. A support guide part f3 is attached to the base of the displacement detector 4, and this support guide part 13 is provided with a recess 13A that engages with the convex part 11A of the guide rail member 11 at its lower end.
A male threaded member 10 is screwed into the center thereof.
このようにして変位検出器４は案内レール部材１１によ

得ることができる。Furthermore, by arranging a plurality of displacement detectors and attaching measuring disks of different thicknesses to each one, a plurality of equal clearance lines can be obtained.
このようにロールの間隙に測定板部を入れるような構成
とすれば、直接ロール表面に測定部を当接させる方式よ
シもその変位量が大きく現われることになる。If the measurement plate section is inserted into the gap between the rolls in this way, the amount of displacement will be large compared to the method in which the measurement section is brought into direct contact with the roll surface.
このような構成の装置をインラインで用いる場合には測
定されたロールプロフィルによシロールの研削の要否を
判断し、オフラインで用いる場合に岐ロールプロフィル
によシロールの研削量を最少限にとどめる。When using an apparatus with such a configuration in-line, it is determined whether or not grinding of the sill roll is necessary based on the measured roll profile, and when using the device off-line, the amount of grinding of the sill roll is kept to a minimum using the branched roll profile.
