Supply of quality re-burned magnesia 92

Welcome new and old customers throughout the guide by the magnesite sinter magnesia, magnesium ore or water extracted from seawater by high temperature calcination of magnesium hydroxide. Strong anti-hydration capacity. Magnesite calcining at 700-950 ℃ under escaping CO2, resulting magnesia as soft porous loose materials, not for refractories; 1550-1600 ℃ calcined magnesite by the so-called burnt magnesia sinter said magnesia. A shaft kiln, rotary kiln calcination temperature equipment once or two-step calcination process, using natural raw materials burned magnesite burned magnesia called sintered magnesia; sintered magnesia their physical and chemical indicators are divided into 18 grades, see GB GB / T 2273-1998. In later called fused magnesia magnesite and other raw materials reach the molten state by arc melting formed by cooling; extracted from seawater called seawater magnesia magnesium oxide formed. 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.
