Main Features of a Modern High Capacity Blast Furnace
Sep 20 2019 · In integrated steel plants production of hot metal (HM) in a blast furnace (BF) is a preferred route globally for ironmaking. The specific cost of steel production is highly dependent on the specific cost of HM in the BF. Hence BF is a very important unit of a steel plant. Modern BF is a high capacity BF having large useful volume.
