While induction heating is not a new technology, it is in fact a green technology and can be a part of an organization’s sustainability program. It does not consume fossil fuels, and it does not produce any hazardous emissions or carbon dioxide.

EFD Induction and IPT Technology merged to become ENRX. The new company is an international supplier of industrial induction heating equipment, as well as solutions for wireless induction charging and contactless induction power supply. EFD Induction manufactures a range of induction heating and induction hardening systems, tube welders and induction heating coils for industries including automotive and renewable energy. IPT Technology provides a range of wireless charging solutions for e-mobility applications and contactless power supply systems for industrial rail applications. The combined company is represented in more than 80 countries and holds over 1,200 patents for induction technology.

We typically start the New Year off by focusing on new technologies throughout the thermal-processing industry in our January issue. With that in mind, let’s begin 2023 by looking at some interesting technological developments that have come across my inbox in the past nine months.

Dr. Valery Rudnev, FASM, received the William Hunt Eisenman Award. Rudnev, retired Director of Science and Technology for Inductoheat Inc. in Madison Heights, Mich., was awarded “for dedicated service to the global materials science community, leadership, development and promotion of induction heating and heat-treating technologies and novel technologies.”

For those of us who would like to gain high-level competence in any profession, it’s critical to explore many of the branches of the tree of knowledge. If you are helping others solve technical problems, deep knowledge in the advertised subject matter is required. Communication skills serve as one example of a crucial additional area of required expertise.

Using the metaphor of cooking a steak to its desired level of “doneness,” this article examines the difficulties involved in “cooking” forging billets in induction coils to their most uniform level of completion.

Cook Induction partnered with Super Systems Inc. to implement a fully electronic SCADA package at its Nadcap-approved facility in Maywood, Calif., which offers heat-treating and brazing (induction, torch and furnace) services. “Having the ability to track and recall furnace data from our desks has made life so much easier,” said Troy Doolittle, Cook Induction’s quality manager. “The new system has improved our ability to stay on top of scheduling and production.”

As our 90th-anniversary year winds to a close, we take a look at an updated reader resource affectionately called the Heat Treat Wheel. Some years ago, we created this source of reader-chosen “evergreen” articles for all of our topic categories. It can be found under our “Featured” tab by clicking on “Heat Treatment Processes.” Admittedly, it looks more like a pie than a wheel, but the wheel is a better metaphor, so we will continue to use that name.

This article looks at the benefits of scalable and configurable induction power supplies.

Ajax TOCCO Magnethermic acquired assets of IQ Technologies Inc. Cleveland, Ohio-based IQ Technologies has been commercializing an intensive quenching (IQ) process for steel parts in the U.S. and overseas for the past 20 years. The IQ process is an effective and alternative way of quenching steel parts. Developed by Dr. Kobasko of Ukraine in 1964, it presents a very rapid and uniform cooling of steel products in water with cooling rates several times greater than that of conventional quenching in agitated oil or polymer. The IQ process is interrupted at an optimal time when the surface compressive stresses reach their maximum value and the part hardened layer reaches its optimal depth. A proprietary computer program is used for determining an optimal dwell time for steel parts of different shapes and dimensions.
