Abstract
The present invention pertains to the field of steel smelting, specifically to a method for steel production in a blast furnace and a converter based on carbon cycling. The method comprises the following steps: Beneficial Effects: The method enables the cyclic utilisation of converter gas. By decarbonising the converter gas and recycling it back into the blast furnace, the content of reductive gases in the furnace atmosphere is enhanced. This promotes indirect reduction within the blast furnace while decreasing direct reduction, thereby reducing the consumption of carbonaceous fuel during the blast furnace iron smelting process and effectively lowering CO2 emissions.
