Abstract
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.
