Abstract: The invention relates to a method and a measuring system for measuring a movable object, for example a lateral guide on the transport path of a casting strand in a metallurgical installation. The system has at least one light source (110) for emitting parallel light beams (130) and a receiving device (120) with a sensor field for receiving the light beams. An evaluation device is used to evaluate the light beams received by the sensor field.

The distances between the individual sensors are likewise known on the basis of the known resolution of the sensor field.

Abstract: The invention relates to a device and a method for cooling a roll. The roll concerned can be a roller in a roll stand or a measuring roll. The device comprises a cooling shell having a cross section in the shape of a section of a circular arc, for covering a surface region of the roll (200), wherein, in the region of an edge of the cooling shell, a bearing is formed with a pivot joint (120) with an axis of rotation running perpendicular to the circular arc-shaped cross-section, for pivoting the cooling shell about the axis of rotation.

Abstract: A system including startup, load, flow, and peak estimation modules. The startup module, during a startup period or in response to a startup of the engine, receives a temperature signal and generates a first condition signal. The load module determines a load on the engine and generates a second condition signal. The flow module, if the first condition signal indicates a temperature of the engine is less than a first predetermined temperature and if the second condition signal indicates the load is less than a predetermined threshold, operates a pump to circulate coolant during the startup period. The peak estimation module estimates a temperature of a hottest metal location on the engine. The flow module increases a speed of the pump if the temperature of the hottest metal location is greater than a second predetermined temperature or the load is greater than or equal to the predetermined threshold.
