Handling of Hot Metal in Blast Furnace Iron Making – IspatGuru

Feb 10, 2016 · Hot metal (HM) is produced by the reduction of descending ore burden by the ascending reducing gases in a blast furnace (BF). It is liquid in nature and gets collected in the hearth of the BF. From the hearth, the HM is tapped from the taphole of the BF after an interval of time. Normally inPerfect BFs, HM tapping rates of 7 ton/min and liquid
