Jun 28, 2017· The second major use of dolomite is in steelmaking. In steelmaking dolomite is used both as a fluxing material and also as a refractory material. For use in steelmaking, the SiO2 (because of its acidic nature) content in the dolomite is to be very low preferably less than 1 %. When it is used as a fluxing material, it is used in calcined form.Dolomite Aggregate - Rongsheng Refractory Materials,,As for the application of dolomite, it can be used in the field of construction, ceramic, glass, refractory material, chemical and industry, agriculture, the protection of environment and energy-saving. Manufacturing Process of Dolomite Aggregate. There are several steps to manufacture dolomiteApplication Of Dolomite In Refractory Industry,Application Of Dolomite In Refractory Industry . Dolomite is a 1:1 double salt composed of magnesite (MgCO3) and calcite (CaCO3). It is the second largest alkaline refractory material after magnesite. It is mainly used to prepare dolomite refractory materials.
