Kast O Lite 30 Li (Low Iron) Plus - is a new generation highly efficient 'Bubble Class' Insulating Castable Refractory. It's easy to work with and one of our best sellers.
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.
- 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.
- The insulating quality of Kastolite 30 LI keeps your forge walls cooler on the outside, and warmer inside. Used either as hot-face or backup lining applications.
Kast O Lite 30 Li Plus is available in 500ml jars, 1 and 2-gallon pails, and 55lb. bag.
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.
Once cured, Kast-O-Lite can be coated with ITC 100 HT to optimize forge efficiency, or with ITC 296A for improved flux resistance.
