Method for the heat treatment of metal aluminium strip
Aluminium Strip for Heating Apparatus
Anodised Aluminium Strip / Aluminium Strip Sizes in China
During the process in which a metal strip is moved in a floating condition, the metal strip is first heated, and thereafter cooled and annealed. In heating the metal strip, the metal strip is heated so that a central portion widthwise thereof is increased in temperature more than that of both edges widthwise thereof. The metal strip is heated in a manner as described whereby a great thermal stress is not introduced in the metal strip and consequently, there is less possibility to produce wrinkles in the metal strip.
