Method for determining improved setup values for a roll stand for cold rolling a strip

Before a rolling pass (i), characterized by a parameter set (Λi), of a strip (100) in a roll stand (10), a minimum and maximum temperature (Tmin, Tmax) and a minimum and maximum coefficient of friction (µmin, µmax) are predefined and, from a setup model (200), limit values (Emin, Emax) for an emulsion actuator (21,..., 23') and setup values for the emulsion actuator (21,..., 23'), for a cooling actuator (41,..., 42') and for a lubricating actuator (31,..., 32') are predefined. During the rolling pass (i), the actuators are set to the setup values. An actual strip temperature (T') is identified by a temperature measuring device (51, 52), and an actual coefficient of friction (µ') is identified from measured manipulated-variable actual values (M'). These are taken as a basis to identify improved setup values either only for the cooling actuator (41,..., 42') and / or the lubricating actuator (31,..., 32'), or, if a change in the applied coolant rate or lubricant rate behaves synergistically with respect to the emulsion rate, additionally also for the emulsion actuator (21,..., 23'). The improved setup values are transferred from the setup model (200) to the parameter set (Λi).
