What’s the maximum temperature an induction furnace can reach?

Induction furnaces do not have a limit to the temperature they can melt and/or heat. However, the refractories and materials that contain the heated or melted material have limitations. The highest temperature typically reached in open air is about 3300°F for a platinum melt. In controlled atmospheres, heating of graphite can achieve temperatures in excess of 5000°F.

What types of metals/materials can an induction furnace melt/heat?

Induction equipment can melt/heat virtually all metals and materials including, gray and ductile iron, steel, copper and copper-based alloys, aluminum, zinc, reactive metals, precious metals, silicon and graphite. If the material to be heated is electrically conductive and resistive, it will couple with the magnetic field and can be heated, inductively. In the cases where the material is non-conductive, a susceptor may be used to provide the energy to heat non-conductive materials.

Can I melt both ferrous and non-ferrous with the same melting system?

Always check with your District Manager to confirm if any changes to the melt system are required. The melt system may have been designed specifically to melt most efficiently either ferrous or non-ferrous applications and, therefore, may require modification to handle materials it wasn’t originally designed for with the same efficiency and productivity. Note that your refractory supplier should be contacted to make certain your refractories are appropriate for the metal you are melting.

What is induction?

When single-phase alternating electric current (AC) from an induction power unit flows through a coil made of copper tubing, an electromagnetic field is produced that induces an alternating current to flow in the metal charge inside the furnace. Resistance to that current flow produces heat that rapidly causes the metal to heat or melt.

How is induction different from gas-fired/fuel-fired?

Combustion furnaces and induction furnaces produce heat in two entirely different ways. In a combustion furnace, heat is created by burning a fuel such as coke, oil or natural gas. The burning fuel brings the interior temperature of the furnace above the melting point of the charge material placed inside. This heats the surface of the charge material and the refractories, causing the metal to melt. Induction furnaces produce their heat cleanly, without burning fuel. The current flow in the metal causes it to heat and melt from within itself. With induction, you heat the charge directly, not the surrounding space.

What is inductive stirring?

In an induction furnace, the metal charge material is melted or heated by current generated by an electromagnetic field. When the metal becomes molten, this field also causes the bath to move. This is called inductive stirring. This constant motion naturally mixes the bath producing a more homogeneous mix and assists with alloying. The amount of stirring is determined by the size of the furnace, the power put into the metal, the frequency of the electromagnetic field and the type/amount of metal in the furnace. The amount of inductive stirring in any given furnace can be manipulated for special applications if required.

What are the advantages of today’s latest induction melting technology?

The highest electrical efficiency ever available coupled with tremendous reliability.

I have an Inductotherm system from the 1970’s and it still works; how do I know when I should upgrade?

Because technology continues to advance, we highly recommend that you contact your District Manager to review efficiency/support enhancements. While your system may be running, it may not be as efficient as today’s equipment and upgrading may greatly enhance your safety and productivity as well as efficiency.

What new technologies are being offered by Inductotherm?

There are many new products and upgrades that can be added to your system to increase its productivity, safety, and reporting capability with minimal investment so it is a good idea to keep in contact with your District Manager for our latest technologies. Another good resource is our website. It is updated frequently with our latest products, upgrades, news and articles, and we suggest you navigate through the site often.

Can I have a quote for a melting system?

We will be happy to send you additional information on our equipment and a quote. Please fill out the on-line form, or contact us by some other manner, so that we can better understand your project goals.

What is the lead time on your equipment/parts?

It varies. We stock some smaller VIP® and VIP-I® power supplies along with a large inventory of parts (that include difficult to find and long lead time components) to ensure the fastest delivery time and maximum up-time at your installation should you need a spare part. Your District Manager can give you an estimated ship date on new equipment. Lead time on parts can be given to you by our Inside Sales Dept.

Can you improve your lead time?

Once we have your order, we do our very best to manufacture your equipment as quickly as possible, without sacrificing any quality. The best way to shorten delivery times is to work closely with your District Manager and let us know your time restraints from the beginning.
