Abstract: Provided is a brake device for braking a rotational movement of a shaft about the longitudinal axis, wherein the shaft is mounted so as to be rotatable about the longitudinal axis in a direction of rotation and in a counter direction which opposes the direction of rotation. Brake devices typically use constant and relatively high braking torques, to ensure a controlled movement of a movement portion, braked by the brake device, in every situation. However, this increases the energy consumption for a movement of the movement portion, and the wear of the brake device. A brake device equipped with a setting device for mutually opposing setting of a braking torque on the shaft during rotation of the shaft in the direction of rotation, and a counter braking torque during rotation of the shaft in the counter direction is provided. Also provided is a method for controlling a brake device.

Abstract: A method and a corresponding computer program product calculate a pass schedule for a stable rolling process when rolling metal strip in a rolling mill. The offset here is varied until the calculated target horizontal force satisfies a predefined limit criterion. The satisfaction of the limit criterion means that the set of rolls and the rolling process are stable. For cases in which a sole iteration of the offset of the working roll does not result in the limit criterion being satisfied, the present invention provides that the draws on the material to be rolled are then changed on the feed side and/or on the outlet side of the rolling stand with constant offset until the calculated target horizontal force satisfies the limit criterion.

The present disclosure further provides a respective measurement device and a respective method.
