Abstract
In a device and a method for recovering energy from at least one metal hot strip bundle (B) which has a temperature of more than 200° C. and is produced in a hot rolling mill (H), the at least one hot strip bundle (B) passes through an energy recovery device (3). In order to recover energy, a gaseous medium (G) flows around the at least one hot strip bundle (B) within the energy recovery device (3) such that said hot strip bundle absorbs energy, particularly heat, dissipated by the at least one hot strip bundle (B), thereby providing a technically simple method and a corresponding device for recovering energy, both of which can be used for any kind of hot strip, independently of the further processing thereof. Furthermore, CO2 and energy can be saved.
Claims21
A method for recovering energy from at least one metallic hot strip bundle which is produced in a hot rolling mill and which has a temperature of more than 200° C., the at least one hot strip bundle being arranged at least partially in an energy recovery device, the method comprising:
- for recovery of energy, flowing a gaseous medium around the at least one hot strip bundle within the energy recovery device such that said medium absorbs energy from the at least one hot strip bundle.
A device for recovery of energy from at least one metal hot strip bundle produced in a hot strip mill and being at a temperature of more than 200° C., comprising an energy recovery device within which the at least one hot strip bundle can be arranged, wherein the energy recovery device is configured such that energy transfer takes place from the at least one hot strip bundle arranged within the energy recovery device to a gaseous medium flowing through the energy recovery device.
