Reducibility Of Iron Ore And Coke Rate In Blast   Furnace

Reducibility Of Iron Ore And Coke Rate In Blast Furnace

Factors affecting Coke rate in a Blast Furnace – Blast furnace coke rate reduces by around 2 % with the blast temperature increasing by 100 deg C. 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.
