Generally, electric power consumption is insidious because it is not seen and is not considered enough by operating personnel. The following is a summary of power consumed in a typical heat treat plant.
Technological change in many industries is often driven by advances in basic science, a move to digital transformation or simply the disruption of the status quo. In manufacturing, the focus on the ability to maintain a process with precision and repeatability based on supply-chain management is also crucial and has led to important advances in industries that make safety and quality imperative.
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 vacuum furnace industry has searched for many years for the ideal material to be used in fixtures and grids for processing workloads at elevated temperatures. The support structures should be lightweight to achieve desired metallurgical results during the cooling phase of the process cycle.
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.
