  • SETTING AGENT ACCELERATOR FOR REFRACTORY MATERIAL
    Publication number: 20120252653
    Abstract: The present invention relates to a setting agent accelerator for use with an ultra-low cement, low cement and regular castable refractory materials and a method of applying the refractory materials using the setting agent accelerator to form a refractory structure or lining. More particularly, the invention is directed to a setting agent accelerator for use with an ultra-low cement , low cement and regular castable refractory material for preserving or maintaining the safety lining and the working lining of refractory structures or linings from mechanical erosion and/or attack by corrosive materials such as those produced during manufacture of cement, lime, metals or metal alloys including acid and basic slags. The setting agent accelerator has a set accelerating amount of sodium nitrate, sodium nitrite or mixtures thereof, calcium hydroxide and water.
