Torpedo Ladle Cars are used to transfer molten iron from the iron-making unit to the steel making section. Torpedo ladle can also be used as a refining vessel for desulphurisation / dephoshporisation by injection of powdered reagents into molten iron through lance. The reagents react with the sulphur/phosphor present in molten iron and separate out from iron as slag.
Hot Metal Ladle is used to transport hot iron from Blast Furnace to Hot Metal Mixer. No treatment is undertaken in this ladle.
