| Abstract: | Through analyzing the mechanism of carbon - oxygen reaction, the method that replacing the aluminum with carbon powder for preliminary deoxidation in earlier stage of the LD tapping were adopted. The testing result showed that the consumption of aluminum block was reduced by an average of 0.16 kg/t, the frequency of replacing the SEN for nozzle -clogging were reduced by 45.8%, and the castability of the molten steel were also improved. Finally, it was proved that good economic and quality benefit could be achieved. |
