Iron Steel Slags

Activity of Iron Oxide in Steelmaking Slag | SpringerLink

Simultaneous distribution of phosphorus and oxygen between liquid steel and slag was recently measured by the present authors.[26, 27] The experimental conditions differed from those of earlier investigators,[1, 2, 5, 6, 13, 15, 17, 23] because the liquid steel contained both oxygen and phosphorus while P 2 O 5 and MgO were simultaneously ...

Abstract. Steel slag is a byproduct of the steelmaking and steel refining processes. This paper provides an overview of the different types of steel slag that are generated from basic-oxygen-furnace (BOF) steelmaking, electric-arc-furnace (EAF) steelmaking, and ladle-furnace steel refining processes.
