A quality vacuum furnace isn’t just about design, it requires proper procedures and maintenance to keep it working at its best. This course looks at the critical areas of preventative maintenance and provides a look at predictive diagnostics that will help keep the system top notch.

Vacuum Maintenance (Part 1)
Patchwork repairs (that all too often become permanent) and temporary fixes are poor substitutes for properly planned and well-executed maintenance activities. But how do we accomplish this? Let’s learn more. Having a good preventive-maintenance (PM) program for your vacuum equipment ensures years of reliable operation.

What Constitutes a Good, Workable Vacuum Maintenance Program (Part 2)
The second part of this vacuum preventive-maintenance (PM) explores the need for understanding the heat-treat process(es) and comparing design ratings/limitations of the equipment. It also discusses what to expect from the original equipment manufacturer (OEM) or third-party supplier.

Vacuum Furnace Hot Zone Upgrade and Improvement
Vacuum furnace users encounter unique maintenance issues. Hot-zone longevity has been an issue that can be improved by using carbon composite (CC) products. CC plate is used for hot-face protection and CC profiles for edge protection. A complete CC hot zone has been developed that provides an extremely hard-wearing surface designed to withstand gas erosion and accidental operator damage.

Titanium Gettering for Vacuum Furnace Brazing
Titanium turnings are an excellent “gettering” agent for use in vacuum brazing furnaces and are best used as part of a shop’s furnace maintenance schedule. Because titanium is highly reactive with oxygen, it will readily react with any available oxygen in the vacuum furnace to form tenacious titanium oxides during furnace heating, thus effectively reducing the amount of free oxygen moving about in the furnace chamber during any brazing process.

Critical Areas in Vacuum Furnace Preventive Maintenance
Proper maintenance of all types of furnaces is important, but maintenance on vacuum furnaces is especially critical to their operation. This article looks at common problems and solutions with vacuum furnaces, when and how to perform maintenance, and tips on how to set up preventive-maintenance programs.
