The Basics of an Induction Melting Furance

For companies that do any form of casting or metal refining, an induction melting furnace is a vital part of the operation, which is why it is so important to ensure that your business has invested in the best possible induction furnaces for the job you are facing.

An induction melting furnace uses a high voltage electrical source from a central coil to induce a low voltage, high current that goes through the metal. Similarly to an induction or convection oven, there are multiple ways to transfer heat, and this is just one of them. Induction is a highly effective form of heating that has been used for many years.

The heart of an induction furnace is the coil, which is made of a hollow piece of heavy duty copper tubing. Copper is used because it is such a great heat conductor. The col shape is typically contained within a steel shell along with a magnetic shield. The shield is there to prevent the shell from heating up as well.

Water cooling is used to ensure the system does not overheat. The water is cooled using a cooling tower and constantly recirculated, so that a tremendous amount of water is not constantly needed to run the furnace. This saves on ongoing costs. The constant cooling also allows the furnace to last longer, which lowers ongoing costs.

While there are other types of furnace that can be used for this type of work, the induction melting furnace is the best option due to its effectiveness and efficiency. Some companies can save money even further by investing in a used induction furnace. While there is little to replace such a need, the uses of an induction furnace are specific, which means they are not universally needed. If a forging company is going out of business, you can typically find a used induction furnace for sale.

Starting a new business can be a daunting task. The best way to prepare yourself is to research everything there is to know, which includes the best options for the equipment and machinery you will need. For casting and refinery work, there is no better option than the induction melting furnace.
