Abstract

The mixing quantification in a gas-stirred ladle with off-centered bottom injection was investigated. Industrial trials in a ladle metallurgy furnace (LMF) were performed to investigate the time-dependent change in concentration of various elements in the steel during the addition of a Silicomanganese (SiMn) ferroalloy into unkilled steel. Alloy mixing is measured after a SiMn addition with alloy recoveries over 90%. The results showed that mixing times depend greatly on the definition of mixing and the sampling location used to infer the state of mixing.
