Abstract

The invention relates to a method and a device for convective heat transfer between a heat transfer medium and a surface, in particular the front face of a wound metal strip in the form of a coil, said surface being impinged upon by the heat transfer medium by means of at least one nozzle wall. The heat transfer medium can be a fluid or a gas. The device is characterised in that at least one of the nozzle walls (10; 11) and the surface to be impinged are mutually mobile during the heat treatment. In a preferred embodiment of the invention, the nozzle walls can be rotated about a rotational axis (71), which corresponds to the primary axis (70) of the coil, or is substantially parallel to said primary axis.
