摘要： As sections of a rolled product (1) pass through a cooling path (2), they are initially cooled in a first cooling phase by front cooling devices (6). The sections are then not cooled in a subsequent second cooling phase. They are finally cooled again in a subsequent third cooling phase, by rear cooling devices (8) of the cooling path (2). A control device (10) of the cooling path receives in each case an initial energy value (EA) exhibited by the sections before they pass through the cooling path (2). The control device furthermore receives a target energy (El *) and a target enthalpy (E2*). The control device (10) determines a first target cooling medium profile (K1 *) on the basis of the initial energy value (EA) and the target energy (E1 *). The control device controls the front cooling devices (6) in accordance with the first target cooling medium profile (K1 *) while the respective section is passing through the front cooling devices (6). The control device (10) determines a second target cooling medium profile (K2) on the basis of an expected enthalpy for the respective section in the second cooling phase and the target enthalpy (E2*). The control device controls the rear cooling devices (8) in accordance with the second target cooling medium profile (K2*) while the respective section of the rolled product (1) is passing through the rear cooling devices (8).

摘要： A control device for a cooling track for cooling a rolling product accepts at least partially characteristic information for a starting enthalpy value. The control device (8) determines a refrigerant volume progression (K) such that a heat volume corresponding to the difference between the starting enthalpy value (EA) and a prespecified end enthalpy value (EE) is removed from a rolling product segment (12) of the rolling product (5) during the movement of said rolling product through the cooling track (1). The control device (8) determines the refrigerant volume progression (K) independently of whether a prespecified end temperature value (TE) assigned to the end enthalpy value (EE) is reached at the end of application of refrigerant (6) to the rolling product (5). The control device (8) applies refrigerant (6) to the rolling product segment (12) during its passage through the cooling track (1) according to the determined refrigerant volume progression (K).
