Abstract (en)
A gas emitted from float nozzle units (21) keeps a metal strip (A) in a floating condition while a heated gas emitted from heat transfer nozzle units (22) is blown onto and heats the metal strip for a heat treatment. The gas flow rate through the float nozzle units is not reduced beyond a certain level such that the metal strip can be kept in the floating condition while the gas flow rate through the heat transfer nozzle units is controlled independently of the flow rate through the float nozzle units and may be reduced to zero. <IMAGE>
