Abstract
An efficient long-service-life blowing method include the steps of introducing vanadium extraction converter flue gas and decarburization converter flue gas into an oxygen combustor; obtaining first-purity CO—Nmixed gas through the vanadium extraction converter flue gas; obtaining second-purity CO—Nmixed gas through the decarburization converter flue gas; obtaining O—CO—Nmixed gas through the decarburization converter flue gas; obtaining first-purity COgas through the second-purity CO—Nmixed gas; and using the first-purity CO—Nmixed gas for bottom blowing of the vanadium extraction converter, using the second-purity CO—Nmixed gas as a carrier gas for blowing iron ore powder into the vanadium extraction converter, and using the O—CO—Nmixed gas and the first-purity COgas as a carrier gas for bottom blowing of the decarburization converter and bottom injecting of lime powder into the decarburization converter.
