Types of Metal Melting Furnaces | Bizfluent

The insides of these furnaces are lined with clay, blocks or bricks which protect the furnace's interior from heat, abrasion and oxidation. To melt the metal in the furnace, workers add layers of metal such as ferro alloys, limestone and coke. The limestone reacts with the metal, making the impurities float up to the surface of the melting metal.
