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.

Method of and device for controlling or regulating a temperature

Energy is recovered from steel products produced in a steel mill where the products are transported into a storage area by first extracting heat from the steel products prior to or after transport into the storage area by heat exchangers for a predetermined period in which residual heat of the steel products is transferred by the heat exchangers into a heat-transfer medium to heat same. The heated transfer medium is then transferred via heat-transfer transport lines for power generation or for direct use of the process heat in other heat consumers. This transport of the heat-transfer medium from the heat exchangers to the power-generating plant in the heat-transfer transport lines is carried out only at pump feed pressure or using as a heat-transfer medium liquid mineral or synthetic thermal oil or a salt melt so as not to build up a steam pressure above 2 bar.
