PURPOSE: To reduce a thickness variance of cemented film layer so as to shorten a treating time by continuously heating a non tight closure container filled with a cementing agent/objective metal part while passing a heating furnace and making an in-furnace temp. uniform, etc.
CONSTITUTION: A non tight enclosure container 1 filled with a cementing agent/ objective metal part is transferred into an inlet side evacuating chamber 3, replacing the container inside with an inert gas etc. Sucessively, the container 1 is transferred to an external heating tubular heating chamber 54, subjecting to pack cemementation with elevating the container 1. Subsequently, the container 1 is transferred to a tubular cooling chamber 6, subjecting to forced cooling. Further, the container 1 is transferred to the delivery side evacuating chamber at the outlet side of the cooling chamber 6 and is carried out to outside atmosphere.
