Unlocking Green Potential: Ten Advantages of Induction Heating in Manufacturing

Fri, 22 Dec 2023 20:30:00 GMT

In the ever-evolving landscape of manufacturing, the push for eco-friendly practices is gaining importance. Induction heating, a technology making waves across industries, shines as a green alternative with numerous benefits. Using electromagnetic currents, induction heating rapidly warms metal, ensuring precise and controlled heating without direct contact. ThermESC induction heating technology offers speed and accuracy without resorting to open flames or fuel combustion.

Let 's explore ten advantages driving its adoption and reshaping manufacturing landscapes:

Improved Energy Efficiency

One of the primary green benefits of induction heating is its exceptional energy efficiency. Unlike traditional heating methods such as gas or flame heating, induction heating directly transfers energy to the material being heated, minimizing heat loss. This efficiency results in lower energy consumption, ultimately reducing the carbon footprint associated with manufacturing processes. Beyond its direct impact on energy consumption, induction heating also contributes to energy conservation by eliminating the need for preheating or extended warm-up periods. This aspect further enhances the overall operational efficiency. With ThermESC, the manufacturing processes are made exponentially more efficient.

Reduced Emissions

Induction heating's eco-friendly profile extends beyond its minimal emissions. Unlike conventional heating methods that often rely on fossil fuels, induction heating operates without open flames or combustion processes. This not only minimizes the release of harmful pollutants into the atmosphere but also reduces the carbon footprint associated with the extraction, transportation, and consumption of fossil fuels. After-all, Induction heating is all about keeping things clean in manufacturing. With ThermESC we ensure the manufacturers remain eco-friendly and stay on top of the changing environmental rules.

Precision in Heating Control

Induction heating provides precise temperature control, allowing manufacturers to heat specific areas as needed. This accuracy minimizes waste and prevents overheating, making resource use more efficient. Precise heat targeting also boosts the overall quality of manufactured products. It ensures each component gets the exact characteristics needed for top-notch performance, meeting high standards and customer expectations. This precision sets the stage for consistent, reliable, and excellent end results. Therefore, ThermESC believes induction heating is not only a plus point but crucial for precise manufacturing.

Shorter Processing Times

Induction heating significantly reduces heating and processing times compared to traditional methods. The rapid and efficient heat transfer enables manufacturers to streamline production processes, resulting in increased productivity. Shorter processing times not only enhance operational efficiency but also contribute to energy savings and reduced environmental impact.

Extended Equipment Lifespan

Induction heating isn't just about making equipment last longer; it's also about lessening the impact on the environment from making and getting rid of them. Because the heating source doesn't directly touch the material being processed, tools and equipment have way less wear and tear. This keeps them going for much longer, so there's less need to replace them all the time. With ThermESC not only do manufacturers save money, but having equipment stick around longer also makes the whole manufacturing process more eco-friendly.

Resource Conservation

The precise and focused heating power of induction heating is a game-changer for resource conservation. Manufacturers can cut down on materials since there's minimal waste during heating. This not only trims raw material use but also reduces the energy needed for material production, highlighting induction heating's eco-friendly edge.

Improved Workplace Safety

Induction heating offers a safer working environment compared to traditional heating methods. With no open flames or hot surfaces, the risk of accidents, such as fires or burns, is significantly reduced. This not only protects the well-being of workers but also mitigates potential environmental damage resulting from workplace incidents.

No Combustion Byproducts

Unlike combustion-based heating methods, induction heating produces no combustion byproducts such as ash, smoke, or particulate matter. Without these pollutants, the air quality at workplaces gets a serious upgrade, so no need for those pricey and environment-hassling emissions control systems. After all, cleaner air isn't just good for the planet, it's also a solid win for the people on the production line.

Versatility and Adaptability

Induction heating stands out as a flexible technology that seamlessly fits into different manufacturing processes. Whether it's for brazing, annealing, or hardening, induction heating systems are adjustable to meet precise heating needs. This flexibility empowers manufacturers to fine-tune their processes, curbing waste and minimizing energy usage across various applications.

Reduced Carbon Footprint

By blending all the mentioned advantages, induction heating actively lessens the carbon footprint of manufacturing.

Five Industrial Challenges Solved with Induction Heating.

Thu, 26 Oct 2023 15:46:00 GMT

Induction heating has been around ever since Nicola Tesla discovered and harnessed the phenomena. His industrial applications made much of the modern world we know today possible. So what exactly is Induction heating? For most applications it is the use of an alternating magnetic field on an electrically conductive part. The magnetic field pushes and pulls electrons within the material. The energy used to do this is dissipated as heat within the part. When properly controlled through coil design and current control, this can produce precise, repeatable and predictable results. This can be seen in modern induction stoves in many kitchens around the world. These stoves require a special pot with a bottom that can accept the magnetic field. Precise current control through an engineered coil provides even controllable heat with a nearly infinite temperature control.

But did you know that Induction heating has solved many industrial challenges as well?

#1 Removal of worn-out boiler tubes from a tube sheet. (Shown Above) The issue: In large industrial boilers as found in many power plants water is fed in to a large header then up through small tubes to another header where the heater water or steam is gathered and sent to be used other places in the power plant. These tubes degrade over time and must be replaced. Within an industrial application these headers my be 3” or thicker and 48” in diameter with 1000’s of 2” diameter holes where the tubes are inserted and then rolled and expanded into the holes. In the past skilled technicians used cutting torches to slice the tube and then beat it out with chisels. Many times this resulted in damage to the tube sheet that required welding and machining prior to fitting and rolling in new tubes.
The solution: Use a specially designed portable induction machine with a specially designed internal coil. This heats the tube rapidly where it is rolled into the tube sheet. The tube reaches 2500F (Approximately 1370C) within 30-90 seconds. This rapid heating causes the tube to attempt to expand but, since it is constrained by the tube sheet and is heated to a malleable temperature, the tube shrinks. At the same time a hydraulic puller can be used to pull the hot tube out while it is still hot.
#2 High Temperature Testing/Thermal Cycling The issue: High temperature testing can be difficult as normal resistance heating methods are limited by the melting point of the heater elements. The higher the temperature the more difficult this is to achieve.
The solution: Induction, when engineered correctly, does not have any top temperature limit. One example where an induction machine and an engineered coil, test cycles can easily be run to 4000F (2204C) where the only limitation is the support of the part or material being subjected to these high temperatures. These testes were done to evaluate high emissivity coatings and catalysts that normally run at excessively high temperatures.

#3 High Speed Curing of Coatings The Issue: Protective coatings can take time to dry or must be melted on to provide an adequate coating bonded to the substrate. Coating Rebar, Angles, bars and much more was done using industrial gas fired ovens moving material through these ovens at speeds up to 300 feet per minute.
The solution: custom built induction machines were used along with engineered coils to provide heat to the parts prior to coating them. For powder coated parts these bars pass through the powder booth shortly after the induction heating. This adds enough heat to melt the powder and adhere to the parts consistently and evenly and since the heat is so fast, it's only on the outer surface causing a rapid cooling after the coating adheres. This greatly reduces the production line length. The same can be done for painted on products, force curing the paint shortening the overall line length and removing a source of heat and CO2 within assembly plants.

#4 Thermal Expansion
The issue: Large heavy shrunk on parts of a Turbine or Generator rotor need to be removed to repair or replace the part or components underneath. In the past Electrical resistance heating or flame rings were used to heat and thermally expand large components for removal. Electric resistance has limitations in its total heat input and flame rings can severely affect the metal or burn adjacent components and combustion byproducts are poisonous to humans.
The solution: Custom designed portable induction heating equipment and flexible coils are used to apply the magnetic fields and heat in the appropriate places to thermally expand these components for removal. This is not limited to the power generation industry. Applications can be found in Steel Mills, Paper Mills and Sugar Plantations to name just a few.

#5 Disassembly of Rusted Nuts and Bolts The issue: In many industrial places bolted flanges are common. These flanges are outside and exposed to the weather and may become corroded or rusted to the point where they cannot be removed by simple torquing methods.
The solution: Induction coils can be wrapped around these rusted and frozen nuts. Then when the heat is applied two things happen. The rapid expansion helps to break the bond formed by the iron oxide and the second is the further degradation of the rust into finer particles. These smaller particles no longer lock the nut to the threads allowing for the mechanical turning and removal of the nuts.

Note: These are just a few of many industrial applications for Portable or Stationary induction heating machines. New applications are found every day.

“If I were designing this machine…”

From Field Service Engineer to Industry Innovator: A Journey Through Induction Heating Challenges and Solutions

While working in the Induction Heating industry as a field service engineer, time and time again, I found myself saying "If I were designing this machine, I would do it this way" It was sometime in 2007, when a customer of my former employer was having trouble with a machine. I helped them diagnose the issue over the phone and shipped them parts to repair the machine..... 3 times within a few days. Each time I came to the same conclusion, it was either a failed inverter switching device or the inverter driver board. Now normally if the customer couldn't diagnose and repair with my help over the phone on the first attempt, I would have been on the next flight to get their machine back up and running. The problem was that this customer was on the other side of the globe in Australia. By the third failed attempt the customer finally bit the bullet and asked for a service call.

In discussions with the customer, they suggested that in order to expedite my entry into the country that I claim that I was going to Australia for a "Holiday". I thought, what a great idea... In fact, I am going to take someone with me and enjoy the down under! I immediately called my girlfriend at the time (now my beautiful wife)and said, can you get a couple weeks off from work and go to Australia with me? She was excited at the opportunity but unfortunately, she had just started a new job and wasn't able to take vacation for a year. I then called my brother and made the same offer. He said, "That sounds awesome!"; and his time off request was approved later that day. Within 48 hours, we were on a flight..... Nearly 20 hours later we were on the ground in Sydney attempting to enter the country. After a solid 30 minutes of questioning by the authorities as to why we would just last-minute book flights from the US to Australia for a holiday they finally let us through. A brief flight to Melbourne, where the customer picked us up for a 2-hour drive and we were finally standing in front of the machine.

In less than 2 minutes, I had confirmed that the switching devices were fine and that the driver board was missing a gate pulse. I then wondered why the replacement parts did not fix the machine. Upon investigation, I found shipping damage consistent with all 3 packages. The guys at the shop said that the packages were open when they arrived. Ah-ha! Customs was opening the packages and not re-packing them. I broke out a soldering iron and went to work to make a good driver board out of the remnants that were on-site. Less than 45 minutes after my arrival I had a functional driver board installed and the machine was heating a part. The owner of the company quickly got word that the machine was running and walked out to investigate. I explained my findings, and he witnessed parts getting heated and then he seemed quite upset. He stormed off to the office with a departing cuss word. I was baffled at his response. He came out 5 minutes later, with a 12-pack of Victoria Bitter in hand. He put the 12-pack down in front of us and declared “It’s time to drink”. The holiday begins….. 24 hours of travel, for less than an hour to fix the machine and the remainder of our two weeks were an amazing time!

4 years later, my wife and I started our own company - ESC Induction. When designing my first machine I drew on multiple instances like the one described here to finally put my “I would do it this way” statements to the test. One example of this was to minimize the troubleshooting that the end user would need to do to diagnose the machine over the phone. I thought about all the times that I had asked a customer to get a multimeter and cautiously reach into the high-voltage cabinet to get a measurement. I then designed a single diagnosis screen into our PLC-based controls wherein everything that could conceivably be measured with a multimeter was placed. I thought about how many times I had asked a customer to decern if the switching devices or the driver board were the issue with rudimentary measurements with a multimeter because they did not have access or the expertise to utilize an oscilloscope. This led to me designing a modular inverter wherein if an inverter is deemed likely to be the issue, the entire inverter is swapped in a few minutes, including the switching devices, the driver board, the cooling surfaces, and the inverter capacitor are all changed simultaneously. Then the inverter can be shipped back to our factory and refurbished by the experts.

My other goal in designing a new Induction system was to achieve higher efficiencies than the rest of the market had achieved. Not only achieving efficiency improvements by reduction of waste energy but also by achieving throughput efficiencies in our customers' production by minimizing downtime in troubleshooting and repairing. Over the years, our team at ESC Induction has continued the tradition of drawing on field experiences. Our systems have evolved into what many of our customers claim to be the best on the market. Easiest to troubleshoot, simplest to repair, and has less power consumption for the same throughput. And that “holiday” trip to Australia was my brothers’ introduction to the Induction Heating industry. This piqued his interest in what I had made my career and like many of us in the industry, he was “hooked”. In fact, after the trip, I asked my girlfriend, Tracy to marry me. She said yes, and she and I started our own business. My brother and best man was our first hire and still is a key part of our business success today.
