high-quality MgO–MA refractories. Another reason for this replacement is that
the properties and performance of second- and third-generation MgO–MA bricks
are competitive with those ofMgO–MK bricks. Table 4 shows some typical properties
of MgO–MA and MgO–MK bricks used in the slag line of a VOD (VAD)
ladle (22) illustrating that properties such as hot strength and corrosion resistance
of MgO–MA bricks approach, or are better than, those of MgO–MK bricks.
