Abstract
The new flux of CaO–Al2O3–MgO system was developed for the refining of low impurity and high quality steel from steel scrap or reduced iron by the combination of EAF–LF–RH. The practical tests of 12 heats using 110 ton scale EAF were carried out at 1873K. The chemical composition of final products was [mass ppm S]=40–60, [mass ppm O]=2–5 and [mass ppm N]=50–70 without special troubles like the damage of refractory materials.
