Interplays of metallurgical factors, such as dissolved oxygen, carbon, and silicon content, that control the molten metal from melting to pouring, have a decisive influence on the quality of the castings. This article focuses on the magnesium treatment and desulfurization carried out during inoculation and nucleation of molten cast iron, assisting in the formation of cast iron. The different types of cast irons are gray cast iron, nodular cast iron, compacted graphite iron, malleable cast iron, and alloyed cast iron. The article provides an overview of the melt treatment processes carried out in cast steel, wrought and cast aluminum, and copper materials.
