METHOD FOR REDUCING THE ENERGY CONSUMPTION OF A ROLLING-MILL INSTALLATION, CONTROL AND/OR REGULATION DEVICE FOR A ROLLING-MILL INSTALLATION, MACHINE-READABLE PROGRAM CODE, STORAGE MEDIUM AND A ROLLING-MILL INSTALLATION

摘要

The method involves stopping operation of a single or multi-part rolling mill (6) during unscheduled milling interval due to fault event. One of sensors or actuators (20-28) is automatically shutdown in energy saving mode during the milling interval. Type of fault is identified, and estimated duration of the milling interval is determined based on the type of the fault. The sensors or actuators set to the energy saving mode are determined by considering duration of the milling interval and time required for shut down and starting of the sensors or actuators. Independent claims are also included for the following: (1) a controlling and/or regulating device for a milling assembly (2) a machine-readable program code comprising a set of instructions to perform a method for reducing energy consumption of a milling assembly (3) a storage medium comprising a set of instructions to perform a method for reducing energy consumption of a milling assembly.
