Product Description Product DescriptionMagnesia Dolomite bricks are made from qualified magnesite and dolomite as the raw materials that are processed throughsecondary-burning (calcinations, fine grinding, briquetting, dead burned). The MGO/CaO ratio is taken as the kind of Mag-dolomitebrick or unshaped monolithics in accordance with customers requirement. Pitch or paraffin impregnation pressed by vacuum isneeded after burned under high temperature. They have the features of high temperature performance and resistance to slag andwidely used in the secondary refining vessels as VOD, AOD; Permanent linings or bottom of converter; Ladle and also the cement kiln.Features of Dolomite BrickGood thermal shock resistance performanceExcellent resistance in slag abrasionGood cold crush strengthHigher temperate resistant with good refractorinesslow creep and better flaking resistant.GoodApplications of Dolomite BrickMainly used for steel refining furnaces like AOD,VOD furnaceSpecifications of Dolomite BrickMgo and CaO content Widely used throughout steel refining furnaces like AOD,VOD furnace BrandProperties MD15MD20MD25MD30MD40Bulk Density (g/cm3)3.033.033.033.033.0Apparent Porosity (%)1010101010Cold Crushing Strength (MPa)5555555555@ 1,500oC x 2hrsPermanent Linear Change (%)---0.35---0.61--@0.2MPa Refractoriness Under Load (oC)17001700170017001700Chemical Composition(%)MgO80.376.370.366.356.3CaO1721273141.0Al2O30.50.50.50.50.5Fe2O30.70.70.70.70.7SiO21.31.31.31.31.2 Q1 : How can you control your quality?A1 : For each production processing, JUCOS have complete QC system for the chemical composition and Physical properties.
