Kast-O-Lite 30 LI Plus Castable - 9.2 lb Pail

Perfect size for the floor of a typical forge. Rated at 3000 °F  beyond steel welding heat). A light weight, high alumina insulating castable with high purity cement. This is a gem.  


  • Kast-O-Lite 30 LI Plus does not have the density and burner durability of MIZZOU (also a 3000 °F castable), but it is lighter and offers superior insulation.
  • This keeps the outside walls of your forge cooler while keeping the heat in.

Typical Applications:

  • aluminum furnace stacks
  • aluminum holding furnace doors
  • furnace discharge doors
  • air heaters
  • hot face or back up linings
  • petrochemical heaters


Kast-O-Lite can be coated with ITC 100 HT, once cured, to optimize forge efficiency, and with ITC-296A for improved flux resistance.

Need more than a pail? We also carry  55 lb bags of Kast-O-Lite 30 Li+.
