>Secondary Steelmaking
Modern steelmaking is classified into two categories: primary and secondary. Nowadays, secondary steelmaking units have become an essential part of the integrated steel plants to supply sophisticated grade of steel for continuous casting.
>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 …
>Electric Arc Furnace Steelmaking and Slag Formation, …
The growth of electric arc furnace (EAF) steelmaking in North America has occurred mainly in the past 40 years due to low electricity prices, an abundance of steel scrap (especially near large population centers), and the development of mini and macro steel mills based on metal recycling. Scrap availability and price has made steel produced by remelting in …

>2 Electric Arc Furnace Steelmaking and Slag Formation, …
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.
