| Abstract: | The development course of Baosteel converter combined blowing technology is introduced. Current combined blowing technical parameters and characteristics are described. Metallurgical effects of combined blowing converters under different conditions of bottom tuyeres are compared. Results indicate that the technology of bottom tuyeres without block is favorable to increasing recovery yield of manganese in hot metal, decreasing total iron in finishing slag, lowering [%C] [%O]of liquid steel at the end point and increasing efficiency of dephosphorization and desulphurization. |
