  • Patent number: 11708621
    Abstract: A strip flotation furnace for controlling the temperature of a metal strip has a flotation nozzle bar extending through the furnace transversely to a strip running direction of the strip. The flotation nozzle bar has two opposing first flotation nozzle rows spaced apart by a central region of the flotation nozzle bar. The rows are set up so that corresponding flotation nozzle jets, with a directional component toward the central region, can be generated to provide pressure cushioning for metal strip guiding. A temperature-control nozzle bar extends transversely to and is spaced apart from the flotation nozzle bar along the strip running direction. The temperature-control nozzle bar has two additional opposing temperature-control nozzle rows spaced apart by an additional temperature-control nozzle bar central region. These rows are set up so that corresponding temperature-control nozzle jets, with a directional component opposite to the additional central region, can be generated.
