Learn about our intermediate frequency furnaces and induction melting

Let us introduce the products, intermediate frequency furnaces, and induction melting.

When choosing the best melting furnace for your foundry, it is important to understand how they operate.

Induction furnaces work by transferring thermal energy through a high-voltage primary coil that induces a high current, low voltage, or secondary coil. These types of furnaces are ideal for melting a wide variety of metals while maintaining low melting losses.

There are two primary varieties of these furnaces: coreless furnaces and tunnel furnaces.

Coreless Furnaces: Coils are the main heating component of a coreless furnace. The stove takes its name from the coil, which is made of highly

conductive copper tubing and wound into a helical coil before being placed in a steel casing. To reduce the risk of overheating, the coils themselves are water-cooled through a circulation tower. The frequencies used can vary between 50 cycles per second and 10,000 cycles per second (referred to as mains frequency and high frequency, respectively). The higher the frequency, the more power can be applied to the furnace. Once the material reaches a molten state, the interaction between the magnetic field and the electric current creates a stirring reaction that helps mix the alloy and distribute the temperature evenly throughout the process.

Channel Furnace: Channel induction furnaces consist of a refractory steel casing that holds the heated metal. Connected to this is the primary induction unit. The unit has an iron core with an induction coil wound around it. The heat generated circulates the metal into the main well, creating its own churning action – similar to the one mentioned above. These types of furnaces are suitable for melting low melting point alloys or as a holding chamber for high melting point metals.

Benefits of Induction Furnaces

No matter which type of induction furnace your foundry requires, this type of induction furnace can offer specific advantages that other alternatives cannot match.

Induction furnaces are suitable for melting metals such as gold and silver, copper, aluminum, silicon, brass, and zinc. Steel and iron can also be melted for industrial use.

They don’t require much space to operate, making them ideal for foundries of all sizes. They are also more environmentally friendly than some other alternatives. They are highly energy efficient, which means they do not adversely affect a company’s energy consumption, and they are ideal for foundries looking to reduce their environmental footprint in terms of production.

They have fewer burn losses, higher overall yields, and are easier to automate than alternatives.

When considering which furnace is best for your foundry, consider the benefits of induction melting and whether an induction furnace is right for you. Not only do they save space, but they also reduce losses, save energy, and can melt the most commonly used metal types.
