Steel slag physical properties

Further improvements to the slag resistance of both direct-bonded and carbon-bonded doloma bricks have been made through the addition of high-purity magnesia. Doloma bricks that have been enriched with MgO are typically used in areas of ladles and AOD vessels where higher slag resistance is required. The chemical and physical properties of the direct-bonded bricks used in steel making are shown in Table 6.
