Alumina magnesia castable, As the lining material for ladle and tundish, alumina magnesia castables are mainly combined by hydration and aggregation. They not only have high resistance to
slag penetration and erosion,but also the overall structure has good spalling resistance and good volume stability.
Magnesia Alumina Castables Introduction:
Magnesia alumina castables, also known as ladle castables, is a kind of monolithic material widely used as ladle lining refractories. Magnesia alumina refractory castables, selecting high alumina
bauxite together with sintered magnesium as aggregates and calcium aluminate cement as binders, has exhibited superior spalling resistance, corrosion resistance as well as high temperature
strength in ladle use. The reasons are that Al2O3 react with MgO and formed MgO·Al2O3 phase under high temperature. MgO·Al2O3 phase materials has the characteristics of low thermal
conductivity, minimal expansion rate and superior volume stability under high temperature. Moreover, pure magnesia alumina spinel phase doesn’t hydrate with water, which extensively increased
the strength of magnesia alumina castables.
Features of Magnesia Alumina Castables :
1. Low porosity
2. Low expansion rate
3. Low thermal conductivity
4. High volume stability
5. Great slag resistance
