The most common casting alloy is cast iron, which accounts for more than 70% of annual casting output. This is explained by a number of advantages of cast iron and, above all, better casting properties than other alloys. One of the main processes affecting the quality of cast iron is smelting technology. The use of induction furnaces instead of cupola furnaces radically changes the technology of cast iron smelting. In this regard, there is a need for a more detailed consideration of the features of induction melting.
