Steelmaking process of remaining slag-double slag operation in converter
The remaining slag-double slag operation was adopted to carry out practical industrial experiment in 120 t converter in a steel-making plant.The production data were analyzed and compared with the data obtained from the original remaining slag-single slag process.The results showed that when w(P) in hot metal was 0.12 ％,w(C) at TSC time of the new process was 0.45 ％ and w(P) could be reduced to 0.023 ％.The dephosphorization rate was 81.45 ％ which was higher than the dephosphorization rate of the original process 78.86 ％.w(C) in the molten steel at the smelting endpoint was 0.12 ％ and w(P) could be reduced to 0.013 ％.The dephosphorization rate was 89.52 ％ which was close to the dephosphorization rate of the original process.The apparent metal material consumption was reduced by 5 kg/t,but the production cycle was prolonged by about 5 minutes.
