Mechanoactivated refractory compositions based on aluminum phosphate bonds for melting pots

The paper analyzes the operational properties of stuffed melting pot masses, depending on their composition, activity of the components and used composition of the aluminum phosphate bonds (APB). Found optimal regimes of mechanical activation graphite, and also found the ratio of activated components to non-activated, allowing to achieve performance of strength when saving thermal stability of the composition. Studied in detail properties such as the work of adhesion, density, sedimentation stability of APB. It is established that a decrease in the content APB of aluminum hydroxide, increased acidity and decreased sedimentation stability. Shows the dependence of the strength of laboratory samples of melting pots from burning temperature and the composition of the binder.
