Manufacture the Refractory Brick MGO - Magnesite Brick

Magnesia brick definition. Magnesite brick inquiry is an alkaline refractory material with a magnesium oxide content of more than 85% and periclase as the main crystal phase. Magnesia brick is a refractory brick made of fused magnesia and sintered magnesia at high temperatures. 

Manufacture the Refractory Brick MGO QUOTATION. 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 belong to MgO Refractory Bricks products and belong to alkaline refractory bricks. Why do you say that? This is because magnesium oxide is an alkaline oxide, has the properties of alkaline oxides, and belongs to a cementitious material. White or off-white powder, odorless, tasteless, and non-toxic, is a typical alkaline earth metal oxide, chemical formula MgO. The melting point is 2852°C, the boiling point is 3600°C, and the density is 3.58g/cm3 (25°C). 

Magnesia brick features. Magnesite brick inquiry has high refractoriness, good alkali slag resistance, high softening start temperature under load, but poor thermal shock resistance. Sintered magnesia bricks are made of brick-making magnesia bricks. After crushing, batching, mixing, and molding, they are fired at a high temperature of 1550-1600 °C. The firing temperature of high-purity products is above 1750℃. Unpoured magnesia bricks are made by adding appropriate chemical binders to magnesia, mixing, molding, and drying. 

Use of magnesia bricks. Magnesite brick inquiry is mainly used for steelmaking basic open-hearth, electric furnace bottom and furnace wall, and permanent lining of oxygen converter. Non-ferrous metal smelting furnace, high-temperature tunnel kiln, calcined magnesia brick, and cement rotary kiln lining. Heating furnace bottom and furnace wall, glass kiln regenerator checker brick, etc. Search magnetite brick inquiry manufacturers, click, and send us your specific needs.
