Torpedo Ladle Bricks

As blast furnaces and converters have become larger and more efficient, the use of torpedo cars has increased as it prevents heat loss from hot metal and the cost of construction as well as maintenance is comparatively low

The torpedo car was originally used for transportation and storage of hot metal. But now hot metal pre-treatment (i.e. desiliconisation, desulphurization and dephosphorisation) has been separated from decarburization processing (done in a converter) and it is done in the torpedo car.

Based on the need for corrosion resistance against FeO, Na2O and CaF2, Al2O3-SiC-C bricks have been developed comprising of alumina as the main aggregate, graphite which provides resistance to spalling and slag penetration and SiC which protects graphite from oxidizing..
