Hot metal is conveyed into torpedo
ladles which are positioned underneath the casthouse,
waiting to be transported to the steelmaking plant.
The torpedo ladle commonly has a cylindrical shape
with conical ends and are filled or emptied through
an oval shaped opening in the top of the torpedo
ladle. The torpedo ladle cars are designed for the
least amount of heat loss.
