Ladle Liners

Introduction & Application

These are clay graphite products used for replacing the transfer ladle & holding ladle refractory lining. They have non wetting property & hence provide longer lining life. They are available with baffle plates. Any other specific customization request can be worked upon. They provide best performance below 1600 C. A few of their characteristics include high erosion resistance, quick pre-heating, very high thermal shock resistance & their ability to maintain temperature for a long time. They are easy to replace & repair thereby saving on labor costs & downtime.

Venting The Ladle

  • Ladle shells should be vented to ensure the release of moisture from the Insulcast. Shells with a capacity less than 150 Kg should have four 6mm holes in the base (Including one in the centre) and four around the side, well-spaced out. Shells with a capacity above 150Kg should have five 6mm holes in the base and six around the side.
  • The setting material should be vented using two lengths of string or "spun yarn" tied vertically around the liners so as to make four vents, or for liners over 150 Kg capacity, three lengths to make six vents.

Installing The Liner

  • Place a thick layer of Insulcast in the bottom of the shell.
  • Bed the liner down firmly, squeezing the setting material up the sides until the liner is level with the bottom of the shell.
  • Ram more Insulcast down from the top all around, so that the liner is firmly supported. The liner will rise during ramming, and should finish up 3 – 6mm above the top of the shell.

Drying The Ladle

  • The refractory materials should be allowed to air-set over night.
  • Dry thoroughly for several hours, by torch or in an oven or by firing wood inside.
  • Seal the joint between ladle and liner around the pouring spouts only, with 12mm depth of Salamander Morcem 900 mixed with water to a putty consistency. Do not seal the vents.
  • Thoroughly pre-heat cold ladles, as usual, before use.


It is dangerous to pour molten metal into a newly lined ladle, which has not been properly dried. New ladles should not be filled until all emission of steam has ceased and the liner should be sufficiently hot to char a piece of paper
