Abstract
The billet rolling mill comprises two rolls for shaping a blank, each shaping roll being provided with at least one rolling tool and being rotated about an axis of rotation by a drive motor, and a manipulator subassembly for moving the blank with respect to the shaping rolls. The manipulator subassembly comprises a clamp gripping the blank and a carriage moving the clamp at least along a direction of rolling of the blank. The manipulator subassembly comprises a linear motor moving the carriage along the direction of rolling. The direction of rolling is perpendicular to the axis of rotation of the rolling tool. The linear motor is configured for accelerating the blank and selectively exerting on the blank, either a tensile force, to extract the blank from a gap defined between the rolling tools, or a braking force, to limit a speed of ejection of the blank.
