Lip Pour Ladles
-
In this type of ladle the metal is discharged over the lip, flow is controlled by tilting the ladle using a geared handwheel. Since the metal flows from the top of the ladle, the metal surface must be slag-free or a skimmer must be used to prevent slag entering the mould.
The advantages of lip pouring ladles are that there are no narrow passages in which the metal can freeze so they are ideal for handling small quantities of metal. They are used for pouring small steel castings. They are inexpensive easy to prepare and are immediately ready for use.
The disadvantage is that slag can easily be entrained in the metal stream.
