There is an age-old adage that exists in the heat treating world. That supposition states that “the smaller the vacuum furnace, the faster it will quench.” Our study compared the cooling rates of two distinctly sized High Pressure Gas Quenching (HPGQ) vacuum furnaces- a large 10-bar vacuum furnace equipped with a 600 HP blower motor versus a smaller 10-bar vacuum furnace equipped with a 300 HP motor.
The purpose of this paper is to explain reactions that can occur during a vacuum processing cycle and different methods of preventing these reactions.
In this article, we will highlight some of the essential design requirements needed to provide the proper all-metal furnace for these critical applications.
