In the present work, reoxidation of Al‐killed steel by Ca(OH) 2 in high basicity slag was investigated by using laboratory experiments at 1873 K in MgO crucibles with various amount of Ca(OH) 2 addition into slag. The CaO–SiO 2 –Al 2 O 3 –MgO–Ca(OH) 2 slags were used to study the effect of Ca(OH) 2 on total oxygen content, aluminum loss, and FeO content in the slag. It was shown that total oxygen content decreased with the time when no Ca(OH) 2 was added into the slag, but it first increased and then decreased with the time when the addition of Ca(OH) 2 was made. Moreover, aluminum loss and FeO content in the slag increased with increasing Ca(OH) 2 content.
