Abstract: In desulphurization slag skimming process, the hot metal of different heats shall be brought into slag pot, led to freeze together and hard to break up, in view of this situation a new partitioning agent-lamination material (/%: 6 ~ 15SiO₂, 20 ~35 CaO, ≥50MgO, 5 ~ 15FeO) is developed and manufactured by using waste material in steelmaking system at No2 Steelmaking Plant. With using this lamination material not only the treatment of desulphurization slag is easier but also the yield of slag iron increases to 92% from original 10%, and the environmental pollution is lightening.
