Abstract
Sheet piling and like steel shapes are made in a caliber rolling mill having upper and lower rolls of suitable contour. One of the rolls is axially fixed and the other can be shifted axially in opposite directions so that shoulders of the rolls engage and these positions are stored along with a relationship of axial force and spring constants of the mill frame. The rolling then takes these stored values into consideration.
