quaternary slag series and liquid steel has been established by calculating the mass action concentration of ladle furnace (LF) refining slag structural units to get the sulphur partition ratio between slag-steel of this slag series L
s
=1115 in end LF refining at 1 630 ℃. The measure results of 9 heats 210 t double bottom nozzle argon blowing LF refining slag samples show that to subtract the existing definite system deviation due to restriction on conditions including worksite and oxygen level of slag series
the model is available to reflect the LF refining slag sulphur partition ratio in commercial steelmaking production.
