Abstract Scope The spring steel 55SiCrA produced in a domestic steel factory is deoxidized by Si with “100 t EAF-LF-VD-CC”. The fluoric content (CaF2 = 17.41-22.15%) and the binary basicity (R = 1.9-3.0) of applied LF refining slag are high. To avoid environmental pollution caused by fluorine, meanwhile guarantee the speed of melting slag and smelting effect on molten steel, the structure of refining slag was adjusted. A new fluorine-free slag system was obtained by changing slagging process, adjusting adding amounts of slag-making materials, such as lime, calcium carbide, silicon carbide and so on. This new fluorine-free slag was applied in industrial tests. The results showed that this new fluorine-free slag could meet smelting demands well. The average oxygen content of spring steel 55SiCrA billets could decreased from 1110-6 to 910-6 and the plasticity of inclusions also changed better. All observed inclusion in billets were within the 1400C liquidus.
