Factors affecting Coke rate in a Blast Furnace – IspatGuru
2014-6-29 High top pressure also reduces the coke rate in the blast furnace. With every increase of top pressure of the blast furnace by 0.1 kg/sq cm there is a reduction of around 0.1 % in the coke rate. Decreasing of fines content in the charge materials improves the coke rate of the blast furnace in the range of 0.4 % to 0.7 %.
