Abstract (en)

[origin: EP0133535A2] In the process, for adjustment of the material temperature, in a heat treatment zone (4) following the cooling zone (3), a part flow of uncooled material is admixed to the material cooled in the cooling zone. As a result, the material temperature in the heat treatment zone can be kept constant even with changes in the material throughput quantity and the cooling air quantity being kept constant. <IMAGE>
