Key features of alumina/magnesia/graphite refractories for steel ladle lining
(2000-08-01)
The corrosion resistance of resin bonded alumina/magnesia/graphite refractories containing different kinds of aggregates were investigated when submitted to the action of slags of several CaO/SiO2 ratios. The laboratory ...
Thermomechanical behaviour of Al2O3-MgO-C refractories under non-oxidizing atmosphere
(Elsevier, 2014-11-11)
Al2O3–MgO–C (AMC) refractory bricks are used as linings for the sidewalls (metal line) and bottoms of steel-making ladles. As a structural component of this type of vessel, these bricks undergo mechanical and thermal loading ...
High temperature mechanical behavior of Al2O3-MgO-C refractories for steelmaking use
(Elsevier, 2011-12)
The advantages of Al2O3-MgO-C (AMC) refractories are achieved mainly by the incorporation of graphite and the formation of spinel by solid reaction between alumina and magnesia. Regarding other members of oxide-C refractories ...
