All Industrial Heating Podcasts

1-13-2019 The Heat Treat Doctor, Dan Herring, and Industrial Heating editor, Reed Miller, discuss cooling in this month's podcast.

12-12-2018 Featuring Industrial Heating editor, Reed Miller, and the Heat Treat Doctor, Dan Herring, this month's podcast features a discussion about the different ways materials are heated.

This podcast is a general discussion about how vacuum pressure is measured and how vacuum leak rates and rate of rise testing are monitored in vacuum furnaces.

This installment will introduce the subject of eutectics and how to avoid these undesired metallurgic reactions when they are not intended during vacuum heat treatment.

This installment discussion will introduce the SolarVac Polaris, a leap forward in advanced vacuum furnace controls. We will explore the unique advantages developed in our new and improved furnace control systems.

This installment introduces Halo, a new advancement in hot zone designs. Halo is a ringless hot zone utilizing HEFVAC, a new high-performance graphite board material for improved thermal efficiency. The superior mechanical strength of HEFVAC allowed a self-supporting polygon structure. We explore why we pursued this design concept and discuss its advantages.

This discussion will review the essential issues related to servicing vacuum pumps and common problems encountered by users. It will also look at some of the best maintenance practices to keep your vacuum pumps running day after day without unplanned downtime.

Here is the continuation of an interview about electric power company rebate programs as applied to vacuum furnaces. This installment discusses the use of variable-speed drives to not only save energy but also improve the service life of the vacuum booster, diffusion pump, gas quench motor and pump motors of the water cooling system.

An interview focuses on the work Solar has accomplished – and work it continues to develop – in hot zone efficiencies to reduce electric power consumption, not only to lower operational costs and improve performance but also to win the rebate programs offered by electric power companies.

In the final installment of this three-part series, Bill Jones expresses his vision for the future of hot-zone designs and other considerations in the advancement of vacuum furnace technology.

In this second in a series of three podcasts, an industry pioneer on the forefront of modern furnace technology reviews the present state-of-the-art of hot-zone innovations.

The first in a series of three podcasts looks back over the evolutionary history of hot-zone designs from the beginning of the modern vacuum furnace and discusses a few important developments that helped to shape present-day furnace technology.

This installment provides an overview of reactive brazing in a vacuum furnace and the use of active brazing alloys for successful results in joining titanium and titanium alloys.

This installment is the second in our series on vacuum furnace brazing. The discussion centers on the advantages and concerns of brazing of stainless steel components with nickel-based and copper-based brazing alloys.

This podcast is the first in a series on vacuum furnace brazing. It is an overview of the different types of brazing processes and why vacuum furnace brazing is superior to other joining methods, particularly torch brazing and welding.

Distortion and cracking of parts is a common problem for heat treaters. This podcast is a discussion on how to prevent and reduce the distortion and cracking of tool steels and other ferrous alloys when cooling parts in a gas-quenching vacuum furnace.

This podcast features a discussion on how contaminants develop on ceramic insulators, how contamination affects the operation and performance of a vacuum furnace, and how to keep ceramic insulators clean of contaminants.

A discussion on the importance of measuring and monitoring the trace levels of dew point (water vapor), oxygen and other gases to reduce part contamination through the use of a residual gas analyzer for in-process vacuum analysis, research and development, and maintenance.

This month’s podcast is Part 1 on the importance of measuring and monitoring the trace levels of dew point and oxygen in quench gases to reduce part contamination while processing in a vacuum furnace.

This is the fourth and final podcast in a series on the benefits of vacuum-furnace preventive maintenance. The concluding installment is a discussion about the importance of maintaining hot-zone power supplies.
