Melt (manufacturing)
Encyclopedia
Melt is the term used to describe the working material in the steelmaking
process, in making glass
, and when forming thermoplastic
s. For thermoplastics, the term specifically refers to the plastic in its forming temperature, which can vary depending on how it is being used. For steelmaking, it refers to steel in liquid form.
Steelmaking
Steelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium and vanadium are added to produce the exact steel required.-Older...
