Today, resin-bonded dolomite brick are compositions for steel ladles and AOD use. Dolomite bricks have dead-burned dolomite as their primary constituent.  The benefits of dolomite refractory are well known, especially in the cement industry. 

Types of Dolomite Refractory Brick

Dead Burned Dolomite Brick:

Dead-burned dolomite is produced by sintering dolomitic limestone (CaCO3-MgCO3) at extremely high temperatures to produce a brickmaking raw material that is one-part lime (CaO) and one-part magnesia (MgO).

Dead burned brick used primarily in two applications: steel and cement production. Dolomite bricks are highly refractory and have high resistance to fluxing against chemically basic melts that are rich in lime, including steel-making slags and cement clinker.

Originally used in basic-practice steel converter vessels in Europe decades ago, burned dolomite brick was tar-impregnated to increase slag resistance and reduce penetration.

Resin Bonded Dolomite Brick:

In cement kilns, dead-burned dolomite brick provides optimum compatibility with the cement clinker in the burning zone.
