According to the OECD report “Perspectives on steel by steel-using industries“, the machinery industry is the third largest consumer of steel in the world, accounting for around 14% of global steel consumption. This is followed by the metal products industry, which also consumes around 14% of the world’s steel.
Mechanical equipment such as robotics and manufacturing require strong, durable materials that can withstand a lot of wear and tear. Steel is an excellent choice for these applications because it is strong, lightweight, and corrosion resistant. Yet, one of the first steps to producing a useful steel product in many industries is melting.
Induction melting furnaces provide fast melting rates at maximum efficiency. This allows companies to get the best metal quality possible for their manufacturing products.
Here are main applications that induction furnaces or melting furnaces can be used for in the melting, heating, holding, and pouring operations.
Investment casting : Induction melting is often used for investment casting because they come in a wide variety of air and vacuum furnaces. These furnaces work great for nearly all metals.
Precious metals melting. Steel is precious for many, but induction furnaces can also be used to melt precious metals such as platinum group metals. This allows them to be refined and used for jewelry manufacturing.
Copper melting. Induction furnaces can be used to melt custom castings or casting large bronze structures. They’re built to provide the melting you need for most copper applications with low metal loss and precise temperature control.
Alloy manufacturing. Induction furnaces are popularly used in alloy manufacturing for optimal uniformity and flexibility. Those in alloy manufacturing companies can count on induction furnaces to provide them with the correct amount of induction, stirring each time so every product comes out the same.
Aluminum melting. Aluminum melting is another popular application used for induction melting. Because induction furnaces are energy efficient, they’re considered optimal for converting alumina into pure aluminum and then into aluminum alloys. This is because this process consumes a lot of energy and so the more energy that can be saved the better.
Induction of melting furnace temperature of common metals
The temperature of an induction melting furnace depends on the type of metal being melted and the desired melting rate. For example, the melting temperature of steel is about 2,750°F (1,510°C), so an induction melting furnace for steel would need to be able to reach temperatures of at least that high. The melting rate of the metal is also important, as a faster melting rate will require a higher furnace temperature.
In general, induction melting furnaces can reach temperatures of up to 3,500°F (1,927°C). However, the maximum temperature that a furnace can reach is also limited by the materials used to construct the furnace, such as the crucible and the coil.
Here is a table of the melting temperatures of some common metals
| Metal | Melting Temperature (°F) | Melting Temperature (°C) |
| Steel | 2,750 | 1,510 |
| Copper | 1,981 | 1,085 |
| Aluminum | 1,220 | 660 |
| Gold | 1,945 | 1,063 |
| Silver | 1,763 | 961 |
The actual temperature of an induction melting furnace will also be affected by the power input to the furnace, the size of the coil, and the type of metal being melted. The operator of the furnace will need to adjust the power input and other settings to achieve the desired melting temperature.
It is important to note that the temperature of an induction melting furnace can be very high, so it is important to take safety precautions when operating the furnace. The operator should wear protective clothing, such as a fire-resistant jacket and gloves, and they should be aware of the potential hazards of working with molten metal.
