Estimating the term…
A surface cutting apparatus for hot-rolled products cuts top and bottom surfaces of a hot-rolled steel product continuously or intermittently by passing the steel product between a pair of rotary drums (milling cutters) that rotate in a direction reverse to each other. The apparatus includes a disk having a larger diameter than that of the rotary drums at one or both ends of at least one of the rotary drums. The disk recognizes a gap between the rotary drums, allowing a zero adjustment to be made without excessively pressing the rotary drums. The measurement can be by a non-contact distance meter, eddy-current type sensor or other sensor.
