The raw materials for the production of magnesia bricks mainly rely on magnesite. The production process of magnesia brick is to mix dead-burned magnesia with a particle size of less than 5 mm to a fine powder and mix an appropriate amount of sulfite pulp waste liquid or caustic magnesia as a binder. Compression molding under a press. The composition of magnesia brick is metallurgical magnesia, sulfite pulp waste liquid, and caustic magnesia. Metallurgical magnesia is MgO decomposed from magnesite above 1600℃. Its components are, MgO: 92-93.5%, Fe2O3: 1.5-3%, AL2O3: 0.5-3%, CaO: 1-2.5%, SiO2: 2-2.5%.  Manufacture the Refractory Brick MGO Magnesia bricks ...
