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').
