In order to mitigate CO2 emissions from steel industry, decreasing coke rate by establishing oxygen blast furnace ironmaking process is a favorable way. Yet every improvement in productivity is fundamentally related to better flow distribution of gas across a particle bed and hence total pressure dr...
