Abstract
PURPOSE:To accomplish heat treatment without generating any strain even with a thin metal strip which has hitherto been considered difficult to treat by moving the metal strip from a heating zone to a cooling zone in a floating state while slowly cooling the same. CONSTITUTION:An aluminum strip 6a which is let off in an arrow 30 direction is supplied afloat to a heat treatment device 1, and is heated in a heating device 2. After it is next cooled in a slow cooling device 12 and a cooling device 21, it is wound with a rewinding reel 6b. In this case, the strip 6 is held afloat by operating burners 10, fans 8, 16, 23, respectively between plenum chambers 7 and 7, 15 and 15, 22 and 22. Air of 500 deg.C is blown out from the chamber 7 of the device 2, that of 220 deg.C from the chamber 15 of the device 12 and that of 20 deg.C from the chamber 22 of the device 21, respectively. This cooling gradient is kept below 110 deg.C/m, whereby good products with the low height of the crease of the strip 6 are obtained and the products having no crease are obtained at below 70 deg.C/m.
