The slimmer the ladle, the lower will be the losses, since the melt surface from
Which heat is dissipated will be smaller for an identical ladle volume. A Marked
decrease in temperature loss can also be observed with increasing capacity.
On a 4-tonne crucible-type ladle, for instance, the loss is as low as 2 K/min
(Fig. 22). A simple technique can go a long way towards cutting temperature
Losses: The use of a drum-type ladle, as shown in Fig. 19, may bring down
Thermal loss to a mere 2.5 K/min (related to a 1-t0nne ladle). Even the use of
A ladle lid may bring down the thermal loss significantly.
