Webhot metal, the optimum operational pattern is as follows. First the scrap is charged into the EAF. While starting the meltdown of the scrap with the electrodes, the hot metal is poured into the EAF through the slag door with a rate of 8 to 12 tons per minute. Once the liquid heel in the middle of the EAF is big enough, the HBI feeding starts. Web12.5.1.3 Iron Preparation Hot Metal Desulfurization - Sulfur in the molten iron is sometimes reduced before charging into the steelmaking furnace by adding reagents. The reaction forms a floating slag which can be skimmed off. Desulfurization may be performed in the hot metal transfer (torpedo) car at a location between the blast furnace and
