Material Notes:

Pyrocast PT-190 is an extremely dense alumina based refractory. It is best suited for applications where high velocity metal erosion potential is a problem, due to its strength and abrasion resistant characteristics. Pyrocast PT-190 also provides excellent hot load strength. Pyrocast PT-190 is frequently used for applications such as launders, tap out and burner blocks, and door blades.Information provided by Pyrotek.
