Considerations When Selecting an Induction Heating System


There are few products that are needed in construction and heavy industry more than steel. Up to 50% of the steel produced in the world is used in construction of buildings and infrastructure, while 16% is used for mechanical equipment and another 13% is used in auto manufacturing. Where does all that steel come from? Well, it has to be produced. Producing steel involves melting the raw material of iron ore in huge induction furnaces that reach temperatures of about 2,500 degrees fahrenheit. This not only melts the ore, but it also removes impurities. Other elements, such as carbon, are added depending on what kind of steel is being made and what it is used for. There are steel producers in the U.S. that buy from induction furnace manufacturers, although the U.S. steel industry has been struggling over the past few decades. The U.S. imports most of its steel these days, importing about $27 billion worth annually. The biggest beneficiary of those imports is Canada, which sends nearly 90% of its exported steel across its southern border. Not all steel is made from scratch. Steel also can be made from recycled steel and other metals. In fact, steel is the most recycled product on the planet. It can be a lot cheaper to make recycled steel. When you think about it, induction heating is one of the processes that has immense benefits for industrial players since it is flameless and energy efficient compared to other heating methods. The challenge that many people face however is choosing the right induction heating equipment. So how do you go about the process to choosing the right induction heating coil or inductotherm melting furnace?

The Material Parts and Depth of Heat Penetration
One of the key factors to consider when choosing induction heating equipment is the material parts. You need to first establish the conductivity of the material that you are using. Some common heating equipment in induction heating are inductotherm melting furnace, induction forging furnace, induction melting furnace and steel melting induction furnace. All these types of surfaces that are essential for precision casting business need to have a high conductivity. In the case of inductotherm melting furnace, there is the possibility of using non-conductive parts with conductive susceptor. You need to have a basic understanding of the chemical composition and qualities of the inductotherm melting furnace. Ideally, magnetic materials used in induction heating can be heated more easily compared to the non-conductive material. This means that you will end up using more power when using non-magnetic material. Apart from the material parts, you also need to consider the depth of heat penetration. Different metals have different levels of heat penetration. This means that the overall power consumption will be affected by the material that you are using for your inductotherm melting furnace in induction heating.

Consider the Operating Frequency and Applied Power
The cost of power in metal heating and melting is one of the key factors that experts often focus on. This is because, using the wrong metal for your inductotherm melting furnace can lead to an extensive surge in the cost of power used in induction heating. The good news however is that induction heating tends to preserve a lot of heat which is why it is popular in melting different kinds of metals. In terms of the operating frequency, it is worth observing that larger metal parts require extensive heating meaning that this will to extend the power consumed at the inductotherm melting furnace. If you are undertaking surface heating, then the best option is to choose lower-power frequency. A good rule of thumb to remember in relation to the operating frequency is that the higher the frequency, the shallower heating will take place on your metal surface. It is often though that the basics of choosing the right induction heating equipment are the reserve of industrial experts and metal products manufacturers. Whereas this is so, having some basic knowledge on what is required in induction heating and how the process takes place can save you a great deal of time and energy choosing the right equipment.
