Title:
焼結体の製造方法および加熱炉
Document Type and Number:
Japanese Patent JP6631080
Kind Code:
B2
Abstract:
A sintered body production method includes a first step in which temperature elevation is started based on a first temperature elevation program in a firing furnace in a state where a molded body containing a metal powder and an organic binder is placed in the firing furnace, a second step in which a vacuum degree or a dew point in the firing furnace is measured in the course of elevating the temperature, and a third step in which temperature elevation is performed by applying a second temperature elevation program in place of the first temperature elevation program when the vacuum degree or the dew point measured in the second step does not satisfy a predetermined condition, and temperature elevation is performed by applying the first temperature elevation program when the vacuum degree or the dew point measured in the second step satisfies the predetermined condition.
