<p><P>PROBLEM TO BE SOLVED: To provide a method and a device for preparing process gas for the heat treatment of metallic material/metallic workpiece in an industrial furnace. <P>SOLUTION: In the method and the device for preparing the process gas 3 for heat treatments of metallic material/metallic workpiece, respective process gases 3 are to be fed into at least one of treatment chambers 1, 1 in an industrial furnace 1 having been practically fully prepared, homogenized and heated, and the method is to be carried out both with newly built and practically with already existing installations of industrial furnaces 1 with the aid of the device, wherein the process gas 3 is prepared with compression at temperatures uncoupled from the temperature in the treatment chamber 1, 1, in another process different from the heat treatment process in the treatment chambers 1, 1 within a temperature range up to about 1,250°C, and is rendered usable for economical and low-emission heat treatment. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
