An induction furnace is a type of electric furnace that uses electromagnetic induction to heat and melt metals. It consists of a coil through which alternating current flows, creating a magnetic field that induces heat in the metal placed inside. This method is efficient and allows for precise temperature control, making it ideal for various metalworking applications. These furnaces are commonly used in foundries and metal recycling facilities to melt materials like steel, aluminum, and copper. They are favored for their energy efficiency and ability to produce high-quality molten metal with minimal contamination.
