PROBLEM TO BE SOLVED: To provide a carburizing treatment apparatus with which the heat-loss during carburizing treatment to a work-piece can be restrained and the consumed quantity of energy can be reduced at lower than the conventional method.SOLUTION: A cylindrical directional regulating member 31, with which a shell-wall 11 of a treatment chamber 10 and an induction-heating coil 20, and the work-piece W in the carburizing treatment apparatus 1, are separated, and the carburizing atmospheric gas convected in the treatment chamber, made to flow from the work-piece W side to the shell-wall 11 side of the treatment chamber 10 and the induction-heating coil 20 side is regulated, is arranged. Thus, the heat-interchange among the carburizing atmospheric gas, the shell-wall 11 and the induction-heating coil 20, is restrained. |
