The stronger a material is the greater is the resistance to abrasion. Also stronger refractories are expected to have higher resistance to slag attack. The determination of cold crushing strength (CCS), however, is highly important in case of refractory insulating bricks where bricks have to be porous as well as strong.
INTRODUCTION Dolomite is a calcium and magnesium double carbonate (CaCO3, MgCO3). It is a key raw material in the iron and steel, ferroalloys, glass, alloy steels, and fertilizer industries, among other industries. There are also dolomite chip flooring tiles accessible. Dolomite brick has a number of characteristics that make it an excellent …

Refractories are inorganic non-metallic materials that can meet the service requirements under high-temperature conditions. Lining materials in thermal equipment, materials for high-temperature vessels, and parts in high-temperature devices are refractories.
Sintered dolomite is a key material used in the production of dolomite refractories, which are essential components in various high-temperature industrial processes. The manufacturing of sintered dolomite involves the heating and compaction of dolomite, a naturally occurring mineral composed primarily of calcium and magnesium carbonates.
