摘要： A cooling section for flat rolling stock has a working region, through which the flat rolling stock is guided. The working region can be supplied with a liquid coolant by means of a number of spray beams. The liquid coolant is fed from a reservoir for the liquid coolant to the spray beams by means of a pump and a supply system. Valves are arranged upstream of the spray beams in the supply system. Opening positions of the valves are set by a control unit of the cooling section according to a respective sub-flow that is to be applied to the flat rolling stock by means of each spray beam. Also, the delivery rate of the pump and/or a line pressure generated by the pump in the supply system are set by the control unit according to the total flow that is to be applied to the flat rolling stock by means of all the spray beams.

摘要： Systems and methods for measuring the thermal crown of rolls in-situ (e.g., at high temperature) either inside or outside the rolling mill can include sensors that measure propagation times of mechanical waves through the rolls. In some embodiments, one or more sensors are used to measure the propagation times of ultrasonic waves traveling inside the roll and normal to the roll's axis. These measurements can be taken when the roll is still hot and can be used to determine in real-time the thermal expansion at various points along the roll.

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 flat rolling stock of metal passes through roll stands of a finishing train, and a cooling section, in succession. Initial values which characterize the energy content of rolling stock points are determined, at the latest, when said rolling stock points enters into the finishing train. The rolling stock is tracked as it passes through the finishing train and cooling section. The initial values, trackings, and energy content influences are used to determine expected values for the energy content of the rolling stock. The energy content expected for a predetermined location, which lies between the first roll stand and the first cooling device of the cooling section is ascertained and used to determine a target energy content progression, from the predetermined location until the rolling stock passes out of the cooling section. The cooling devices are controlled based on the target energy content progression.
