| Abstract: | The basic approaches to improve gas recovery ratio were analyzed in theory based on converter gas recov ery system of Baosteel No. 2 steel making plant. The effect of following factors such as converter conditions, raw material supply, air suction rate, recovery conditions, and intensity of oxygen blowing on converter gas recovery ratio was studied. And the effects of air suction rate, recovery conditions and intensity of oxygen blowing are remarkable. The physical measures are put forward for modification of hard and soft ware of converter gas recovery system, and good results can be achieved. |
