After AOD operators switched from Magnesia Chrome refractories to Dolomite refractories, AOD Lining designs have evolved over the years, as well. Now, many lining design use three grades of dolomite; resin bonded, fired dolomite and fired magnesia enriched dolomite. Linings are also zoned by thickness.

 · Dolomite refractories are found in openhearth steel furnaces and the lining of basic oxygen furnaces. To produce dolomite bricks, you need dicalcium silie. During the hightemperature manufacturing process, dicalcium silie dehydrates—an inversion effect which causes the volume to increase 10%.

In the steelrefining process, for example, the use of dolime instead of pure quicklime extends the life of refractory linings. Adding dolime creates MgO in solution in the slag. As MgO particles in suspension provide excellent coating protection, exceptional buffering capacity is assured. Excess MgO precipitates, protecting refractories and tap holes. This reduces the need for gunning .

 · Dolomite after its mining has to undergo several processing before it can be used in various processes. The basic processes in the production of dolomite are (i) quarrying of raw dolomite, (ii) preparing mined dolomite for its use by crushing and sizing, (iii) calcining of raw dolomite, (iv) processing the calcined dolomite further by hydrating to produce hydrated .
