Causes and Recovery of Chilled Blast FurnaceIspatGuru
Mar 31 2013 · A chilled blast furnace (BF) in an integrated steel plant is the cause of serious disruption in the production. It can take sometimes several days or even weeks to bring the BF back to normal production. The chilling of a BF hearth occurs when the temperature of the hot metal (HM) which is tapped from the furnace is very low.
