Abstract
In the heat treatment of heat treatable material in an industrial furnace, in particular for the annealing of annealable material such as, for example, aluminum strip wound into a coil (1), by means of blowing of the annealable material with hot gas jets (8) issuing from nozzles (7), in order to insure a very good and uniform heat transfer from the hot gas stream to the material and a completely uniform temperature distribution in the coil (1), and also the rapid heating thereof, without any need to fear locally partial overtemperatures in the coil, it is proposed in accordance with the invention to move the annealable material such as, for example, the coil (1), and the hot gas jets (8) relative to one another, for example by means of the fact that the coil (1) and/or the hot gas nozzles (7) are rotated about the coil axis, so that the blowing impingement points of the hot gas jets (8) move on the blown surface of the annealable material and all desired portions there can be swept in controlled fashion.
