| Abstract: | The smelting process of fine steel, of which chemical composition required is strict, was described. The steelmaking process is 30t EAF - LF - VHD. The control difficulties and the key of smelting operation for each process is presented, which can ensure chemical composition qualified, such as, dephophorization of EAF to P≤0.001%, desulfurization of LF to S ≤0.003% and desulfurization of VHD to S≤0. 001%. |
