Abstract

Abstract

Liquid steel for continuous casting was refined quickly at the alloy conditioning station in Masteel with the mixture of CaO-SiO₂-CaC₂ to slag and Al, SiCa to deoxidize in the period of 18 min (converter match to cast). The activity of oxygen in liquid steel can be decreased less than 20×10^-6 and FeO+MnO<3% in the final slag, which meets the needs of shaped block cast machine that lubricates with oil.
