Coreless induction furnaces are commonly used in foundries for melting recycled scrap metal to provide molten metal for making castings (Figure 1). A copper coil encircles a layer of refractory material and a powerful electric current travels through the coils creating a magnetic field that penetrates the refractory and quickly melts the metal charge material inside the furnace. The coreless induction furnace is mainly composed of a ceramic crucible, which is surrounded by a cylindrical induction coil. In a coreless induction furnace, electromagnetic stirring of the molten metal bath occurs when power is applied to the furnace. . Short term maximum operating temperature. For modern foundries using coreless induction furnaces to work efficiently, they must keep thermal consistency throughout this process. Furnace / . Coreless induction furnaces usually have charge made of scrap, pig iron and ferroalloys. These have been specifically developed for a variety of metals and some allow for a mixed melting programme. The Coreless Induction Furnace, commonly known as CIF, is an effective furnace type for remelting clean scrap and processing difficult aluminium alloys (such as lithium containing alloys) as well as master alloys. coreless induction furnaces for melting iron. They are mostly used in the production of steel. Its working principle is based on the principle of ac transformers i.e., when the primary is connected to a high-frequency ac supply, eddy currents are induced in the charge to be heated. Their charging and pouring is simple. These can be operated intermittently. All furnace linings have been successfully converted to take advantage of the extended campaign life.
