Torpedo ladles transfer hot metal from the blast furnace to the steel plant and in some cases the liquid iron is treated in the ladle to remove impurities, i.e. S, Si etc. The refractory linings need to have thermal shock resistance, abrasion resistance, impact and corrosion resistance and if the lining is carbon-bonded, it needs to have oxidation resistance. Al SiC C bricks were developed to meet the more arduous conditions experienced in treated ladles. The use of this type of lining has also become more prevalent in untreated torpedo ladles, but fired and phosphate bonded mid and high alumina materials can also be used depending on plant operations.

It depends on how much is being transported, from the blast furnace to the steelworks basic oxygen furnace where i work it is transferred in ladle cars called torpedo cars by the railroad engine, then it is transferred to molton iron ladles to be put into the basic oxygen furnace. There are also Kress pot haulers that carry molten slag to be dumped.
