dolomite can stand temperatures upto 2300ºC. It is widely used as a refractory material wherever steel is refined using Basic Slag. It is used for original hearth installations in the open hearth furnaces as well as for hearth maintenance. These hearths are installed using tardolomite ramming mixes and rammed dolomite.
