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 ...
Slag corrosion of alumina-magnesia-carbon refractory bricks: Experimental data and thermodynamic simulation
(Elsevier, 2016-12-27)
Alumina-magnesia-carbon (AMC) bricks are used in steelmaking ladles, where they are part of the bottom and sidewalls working linings. These refractories can be corroded by liquid slag, especially during tapping and casting. ...

Factors controlling the mechanical behavior of alumina-magnesia-carbon refractories in air
(Elsevier, 2016-04-07)
This work analyzes the mechanical behavior of alumina-magnesia-carbon (AMC) refractories in air up to 1260 °C. AMC refractory bricks are used on sidewalls and bottoms working linings of steel-making ladles. In plant, AMC ...
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 ...
