Kast-O-Lite 30 LI Plus INSULATING Bubble Refractory Castable - 55 lb Bag

15 items left

High Strength Refractory (approx 2000 psi @ forge heat), High Alumina, Moderate Density (90 lb/ft3), Insulating (new generation bubble class) refractory with low thermal conductivity. 

Rated to 3000 °F (well above forge welding heat).  Low Iron (0.9%) for flux resistance.  Hydraulic set.  

It can be used on its own, or as a layer over top of wool (best to toughen up the wool first with our freeze-proof rigidizer to prevent its compression during application), etc. 

Features:

  • KastOLite 30 LI + does not have the density and burner durability of Green Kleen 60, Green Cast 94 or even KS-4V Plus, but it is lighter and offers superior insulation.  These 'Green' Castables have amazing strengths of 9000 psi, but are twice the density of KOL 30.
  • This keeps your forge walls cooler on the outside, and warmer inside.  Used either as hot-face or back-up lining applications.

Kast O Lite 30 Li Plus is available in these sizes:

Also Available in a Faster Setting 'G' version: Kast-O-Lite 30 LI G Plus, which is also available in a 55lb bag, a 2-gallon pail, and a 1-gallon pail.

Tip:

Once cured, Kast-O-Lite can be coated with a thin ceramic reflective coating called ITC 100 HT to optimize forge efficiency, often by over 30%.

SHIPPING TIP:

Do you have more than 1 bag of Castable Refractory in your cart?

If so, the online shipping quotes will probably be wrong!!  The automated shipping algorithm has a hard time calculating that weight/dimension. In turn, the quotes come in WAY TOO HIGH. Please contact us for a manual quote - it will usually be much better!!
