Dolomite is widely used in the production of refractory products due to its unique combination of properties, including high refractoriness, excellent thermal shock resistance, and chemical stability at elevated temperatures. One primary application of dolomite in refractory products is as a raw material for the production of dolomite refractory bricks and shapes. These bricks are used in various high-temperature applications, such as steelmaking, cement kilns, glass furnaces, and incinerators, where they provide excellent resistance to thermal cycling, abrasion, and chemical corrosion.

Moreover, dolomite serves as a fluxing agent and sintering aid in the manufacture of magnesia-carbon (MgO-C) refractories. Dolomite-derived magnesium oxide helps to improve the sintering behavior and mechanical strength of MgO-C refractories, enhancing their performance and longevity in demanding applications, such as steel ladles, converters, and electric arc furnaces.

Additionally, dolomite is utilized as a filler and binder in refractory castables and gunning mixes, where its fine particle size and inert nature help to improve flowability, workability, and bonding strength. Dolomite-based refractory castables are used for lining various industrial furnaces and kilns, providing thermal insulation, erosion resistance, and structural integrity at high temperatures. Furthermore, dolomite can be incorporated into refractory coatings and mortars to enhance their adhesion, thermal insulation, and corrosion resistance properties. Dolomite-based refractory coatings are applied to the surfaces of refractory linings to protect them from chemical attack, oxidation, and thermal shock, prolonging their service life and reducing maintenance costs.

Overall, dolomite plays a crucial role in the production of refractory products by providing essential properties and functionalities that contribute to their performance, durability, and reliability in high-temperature applications across diverse industries. Its versatility and effectiveness make dolomite a valuable resource in the refractories industry.
