Abstract (en)

To shorten the time taken for a carburizing and quenching treatment of an object to be treated, a carburizing and quenching facility 1 is provided that includes: a treatment chamber where at least one treatment related to a carburizing and quenching treatment is performed on an object to be treated W; a transfer apparatus to transfer an object to be treated W; a mounting table 30 that is provided in the treatment chamber and on which an object to be treated W transferred into the treatment chamber is mounted; and a lifting and lowering device that lifts and lowers the mounting table 30 and in which a transfer arm 40 to transfer an object to be treated W into the treatment chamber and outside the treatment chamber is provided in the transfer apparatus, the carburizing and quenching facility 1 includes: a turntable 60 that is disposed in the treatment chamber and performs deliveries of an object to be treated W to and from the mounting table 30 and the transfer arm 40; and a turntable drive device that rotates the turntable 60, in which the turntable 60 includes: a first support part 63 that supports an object to be treated W that has already undergone a treatment; and a second support part 64 that supports an object to be treated to undergo a treatment next, and in plan view, the turntable 60 is provided in a positional relationship such that the first support part 63, a support post 62 of the turntable 60, and the second support part 64 are disposed in a linear arrangement so as to sandwich a rotation axis R of the turntable 60 by the first support part 63 and the second support part 64.
