Where fused magnesia best, the best manufacturers

Also known as sintered magnesia and fused magnesia. The magnesite, magnesium ore or water extracted from seawater by high temperature calcination of magnesium hydroxide. Strong anti-hydration capacity. Magnesite and other magnesia-based raw materials by high temperature sintering process to achieve the degree of the product collectively. A shaft kiln, rotary kiln calcination temperature equipment once or two-step calcination process, with natural magnesite as raw material called sinter magnesia fired magnesia; magnesite as raw material in electric arc furnace smelting reached a molten state cooling It called after the formation of fused magnesia; extracting magnesium from seawater made called seawater magnesia. Magnesia refractories is one of the most important raw material for the manufacture of all kinds of brick, Mg-Al brick, Ramming expected, fettling and so on. Containing impurities for paving hearth steelmaking and so on. Purity magnesia is made from natural premium magnesite flotation purification by light burning, fine grinding, pressure the ball, ultra-high temperature oil shaft kiln calcination. Is brick, unshaped refractory quality raw materials. Midrange magnesia MgO content is 97% of the light burned magnesia as raw materials, pressure the ball, high temperature shaft kiln calcination process from production. Product good degree of sintering, fine crystal, the production of mid-range quality magnesia refractory products raw materials. Fused magnesia is a selection of special A-level or high-purity natural magnesite calcined magnesite particles in an electric arc furnace melt system. The product has a high purity, large crystal grains, compact structure, strong material slag resistance, good thermal shock resistance, is an excellent high-temperature electrical insulation materials, but also the production of high-grade magnesia carbon bricks and monolithic refractories important raw materials. Fused magnesia physical and chemical indicators: the chemical composition of grade MgO% SiO2% CaO% Fe2O3 95 ≥95 ≤2.0 ≤2.0 3.4 96 ≥96 ≤1.5 ≤1.5 3.45 97 ≥97 ≤1.2 ≤1.2 3.45 Refractories Co., Ltd.
