A vibratable, castable refractory composition containing a refractory aggregate, a liquid resol-phenolic ester-cured resin, which can be an aqueous mixture, and an ester is disclosed. The composition may further contain an activating agent to promote ambient temperature curing of the resin by the formation of ester-phenolic polymer bonds; an anti-oxidant metal powder as a strengthener; a slag penetration resistance agent; and a wetting aid and dispersant. Cast refractory components made from the composition exhibit great flexural and compressive strength. The composition and shapes cast therefrom are suitable for use in high temperature refractory applications in reducing or inert atmospheres as are encountered in the ferrous industries. |
