A method for controlling a cooling device which is set up to control temperature of a rolling stock such as a metal strip, which runs through a cooling device along a conveying direction of a rolling train. The cooling device is arranged upstream of the rolling train. The method includes determining total enthalpy of a system formed by the rolling stock; determining a measure for the formation of scale, which includes a scale factor that depends on chemical composition and surface temperature of the rolling stock, and a heat transfer coefficient of the scale; calculating a temperature distribution and/or average temperature in the rolling stock based on a temperature calculation model, in which the determined total enthalpy and the measure for the formation of scale are included; and setting a cooling capacity of the cooling device taking into account the calculated temperature distribution and/or average temperature in the rolling stock.

Method for controlling a cooling device in a rolling train

A method for open-loop and/or closed-loop control of a heating of a cast or rolled metal product, includes the steps of determining the total enthalpy of the metal product from a sum of the free molar enthalpies (Gibbs energy) of all phases and/or phase fractions currently present in the metal product; determining a temperature distribution within the metal product by means of a dynamic temperature calculation model using the total enthalpy determined; and open-loop and/or closed-loop controlling of the heating of the metal product as a function of at least one output variable of the temperature calculation model.

Method and system for the open-loop and/or closed-loop control of a heating of a cast or rolled metal product

A device and a method for cooling metal strips or sheets conveyed on a conveyor line, in particular hot-rolled strips in the outlet of a rolling train. For these purposes, the device includes at least one cooling beam extending across the width of the conveyor line, and the cooling beam features a connection point to which a supply tube for cooling liquid can be connected, and a number of discharge openings arranged along a longitudinal axis of the cooling beam, such that cooling liquid can be discharged through the discharge openings in the direction of the metal strip or sheet that is to be cooled. Associated with each of the individual discharge openings is a respectively adjusted flow area, such that the flow areas of the respective discharge openings decrease in a direction leading away from the connecting point along the longitudinal axis of the cooling beam.

Device for cooling metal strips or sheets

The invention relates to a method for the open-loop and/or closed-loop control of a heating of a cast or rolled metal product, comprising the following steps: &#x2014;determining the total enthalpy of the metal product from a total of the free molar enthalpies (Gibbs free energy) of all phases and/or phase fractions currently present in the metal product; &#x2014;determining a temperature distribution within the metal product by means of a dynamic temperature calculation model by using the determined total enthalpy; and &#x2014;open-loop and/or closed-loop controlling of the heating of the metal product according to at least one initial variable of the temperature calculation model.

An apparatus for the continuous casting of thin slabs, having a strand guide, which is arranged downstream of a permanent mold in the casting direction and which guides the strand output from the permanent mold along a first direction, having an adjoining bending/straightening region, which a mechanism for driving and bending the strand in a second direction, which differs from the first direction, having a cutting device, which cuts the strand into thin slabs, and having a first furnace, which is provided for temperature compensation in the strand, wherein the first furnace extends in an arched manner at least partially over the bending/straightening region and in part along the second direction.

Continuous casting installation for thin slabs

The invention relates to a method of controlling or regulating the temperature of a cast strand () in a continuous casting installation () comprising a control or regulating unit () particularly for controlling or regulating the temperature in a secondary cooling of a continuous casting installation using at least one means for cooling the cast strand, characterized by a dynamic change of at least one set temperature of the cast strand on the basis of data and/or signals that are received and/or determined by the control or regulating unit.
