This handy reference guide provides valuable information regarding critical melting points for Metals and Alloys.
This work is an update of the original reference compilation by Charles F. Burns, Jr., Copyright 1997. The current booklet contains revisions to the original work as well as numerous additions. This booklet should serve as a handy reference for people that work in the metals industry.
A Temperature Uniformity Survey ( TUS ) for a vacuum furnace to satisfy AMS 2750D must be performed using established procedures and methods that fully meet the requirements of the specification and allows for consistent and more accurate results of actual furnace capabilities.
A specific concern to a vacuum furnace user is processing critical work during summer months with high temperatures and high humidity. This same concern could also be a problem on rainy winter months.
Proportional-Integral-Derivative (PID) control is the most common control type algorithm used and accepted in the furnace industry. These popular controllers are used because of their robust performance in a wide range of operating conditions and because of their simplicity of function once understood by the processing operator.
There are many factors that should be considered when investing in a new vacuum furnace. Although price is obviously important, there are many detailed design and other technical considerations buyers should evaluate to ensure that they select the best equipment for their requirements.
The proper selection of a water cooling system to support all aspects of vacuum furnace operation is a critical decision. This booklet highlights the advantages and disadvantages of various systems to help you determine which one will best suit your specific requirements.
The purpose of this paper is to provide a better understanding of vacuum, including an explanation of vacuum, a definition and description of vacuum measuring instrumentation and an explanation of their application to vacuum furnace operation.
