Heat Treat Company Donates Vacuum & Brazing Furnace to Lehigh University

A thermal processing company donated a $300,000 commercial-grade vacuum heat treating and brazing furnace to Lehigh University’s materials science program to help increase opportunities for its students in the field.William R. Jones, Solar Atmospheres CEO and founder

The new addition, known as The Mentor®, was donated to Lehigh University by thermal processing company Solar Atmospheres and its CEO and founder, William R. Jones. Its sister company, Solar Manufacturing, designs and builds vacuum furnaces at its location in Souderton, Pennsylvania, just 23 miles from Lehigh’s campus.

Additionally, Solar Atmospheres built and donated a transformer and water-cooling system that was specifically designed for the application.

“This is a very powerful, advanced piece of equipment that will allow us to conduct important experiments in our metallurgy teaching and research, especially around additive manufacturing, which is a hot topic these days,” explains Wojciech Misiolek, professor and chair of the Department of Materials Science and Engineering at the P.C. Rossin College of Engineering and Applied Science. “And we will challenge ourselves to use it up to its full capabilities for heat treatment of metals.”

“With this donation,” adds Misiolek, “suddenly you have the industry-grade equipment. It’s not a miniature version, it’s what you will see out in the field. Our educational system at Lehigh is very hands on, and we have a reputation for that. This furnace will increase opportunities for our undergraduate and graduate students and help them hit the ground running when they go into industry.”

Applying PID to Temperature Variances in Vacuum Furnaces

Controlling process temperature with accuracy and without extensive operator involvement is a crucial task in the heat treat shop and calls for the use of a temperature controller, which compares the actual temperature to the desired control temperature, also known as the setpoint, and provides an output to a control element. This comparative process relies upon an algorithm, the most commonly used and accepted in the furnace industry being the PID, or Proportional-Integral-Derivative, control.

“This popular controller is used because of its robust performance in a wide range of operating conditions and simplicity of function once understood by the processing operator,” writes Real J. Fradette, a Senior Technical Consultant with Solar Atmospheres, Inc, and the author of “Understanding PID Temperature Control as Applied to Vacuum Furnace Performance” (with William R. Jones, CEO, Solar Atmospheres, Inc, contributing).

The PID algorithm consists of three basic components, Proportional, Integral, and Derivative which are varied to get optimal response. If we were to observe the temperature of the furnace during a heating cycle it would be rare to find the temperature reading to be exactly at set point temperature. The temperature would vary above and below the set point most of the time. What we are concerned about is the rate and amount of variation. This is where PID is applied. ~ Fradette

In this week’s Technical Tuesday, we direct our readers to Fradette’s article at Solar Manufacturing’s website where he and Jones cover the following on PID temperature controllers:

  • Definitions, e.g., Closed Loop System; Proportional (GAIN); Integral (RESET); and Derivative (RATE)
  • Actual operation of a PID temperature controller, including understanding PID dimensions and values; and general rules for manually adjusting PID
  • The art of tuning, a manual
  • Autotuning
  • Tweaking the furnace PID controller
  • and other factors

Solar Atmospheres Invests with Confidence In America

In order to honor newly inaugurated, President Trump, Solar Atmospheres, Souderton, Pennsylvania,  placed an order on January 20, 2017, Inauguration Day, for a large horizontal loading 10 bar vacuum furnace with advanced cooling technology, to be built by sister company, Solar Manufacturing, Inc.  The furnace will have a 6-foot diameter, 6-foot deep graphite and CFC hot-zone and will be utilized for the heat treatment of gas turbine blades for the power generation industry at the company’s flagship plant just north of Philadelphia in Souderton, Pennsylvania. “This shows the confidence we have in improved business conditions going forward and not looking backward.  This investment and installation will approach $2,000,000,” stated William R. Jones, CEO, FASM.

Solar Atmospheres Group Adds Vacuum Pump Services Corp.

VPS LogoSouderton, Pennsylvania: Solar Atmosphere announced the formation of a new vacuum pump servicing company, Vacuum Pump Services Corp. Solar Atmospheres group of companies has over one hundred mechanical vacuum roughing pumps and mechanical holding pumps. Solar currently operates a fleet of vacuum furnaces across the United States many of which are still in operation after 30+ years.  Since mechanical pump life averages five to ten years, depending on usage, it became advantageous for the commercial vacuum heat treating company to establish its own vacuum pump service center.

Currently, there are three employees:  Bob Sandora, Vice President of Operations, a longtime Solar Atmospheres employee with over 40 years of mechanical vacuum pump experience; Steve MacInnes, Manager of Operations with 15 years of mechanical vacuum pump experience; and another recently hired pump technician.

According to William R. Jones, CEO of the Solar Atmospheres family of companies, “We know vacuum pumps, when to have the pumps serviced, and how to service them correctly.  This is the base reason for establishing our own organization.  We have also serviced pumps for other organizations including our competitors.  So we’re eager to share our knowledge and expertise and to offer our services broadly across the industry.”
