Melting Practices:

The different kinds of furnaces utilized in melting outlined in the primary section of this unit. However melting operations usually involve much more than just adding sufficient heat to liquify solid metal. The furnace atmosphere might carefully be controlled to ignore unwanted impurities and loss of essential elements. Unwanted impurities are eliminated by refining or degassing. Ultimate solidification structure may be improved by inocculation. In this section, we are going to explained these techniques generally which might be used after tapping in some cases and when melting of the metal in few other cases as well.
