IRON AND STEEL - Records Collections

2021-10-13  All contemporary steelmaking processes convert pig iron, scrap, or direct-reduced iron, or mixtures of these, into steel by a refining process that lowers the carbon and silicon content and removes impurities (mainly phosphorus and sulfur). Three major furnace types can be used for making steel:
