Scrap can be of various qualities, depending upon the grade to be cast. In addition, other iron units, which are purer than scrap—for example, iron produced from iron ore that contains carbon (a pig iron) or a product called hot briquetted iron (HBI) from direct reduction of iron ore—can be added, if very high-quality steels are to be produced that require strict chemistry control.

Metallurgical Slag

The slag cover protects the metal and matte from oxidation and prevents heat losses due to its poor thermal conductivity. In order to achieve these objectives, slag must possess a certain optimum level of physical properties, such as low melting point, low viscosity, low surface tension, and high diffusivity; and chemical properties, such as basicity, oxidation potential, and …
