The aluminum-magnesium refractory castable with age of 60~80 times
The aluminum-magnesium refractory castable is a refractory castable prepared by using high alumina bauxite clinker as aggregate, high bauxite clinker powder and magnesia as powder, and sodium water glass as binder.
Feature
The aluminum-magnesium refractory castables the average age of ladle is 60~80 times, and the consumption of refractory materials per ton of steel is reduced by about 70% compared with clay-coated steel bricks.
Application
The aluminum-magnesium refractory castable is mainly used for the inner lining of steel drums, ladle and tapping troughs, and has been widely used in the ladle for medium and small die casting.
