Product Description
The main components of light-burned magnesia balls and the benefits of using light-burned magnesia balls Light-burned magnesia balls are made of industrial magnesia and refractory kaolin as the main raw materials. Long cycle; good chemical stability, no chemical reaction with materials, good high temperature resistance, the highest heat resistance temperature of refractory ceramic balls can reach 1900 degrees. It is especially suitable for high and low temperature shift furnaces, reforming furnaces, hydroconverters, desulfurization tanks and methanation furnaces in chemical fertilizer plants. It plays the role of dispersing gas and liquid, and supporting, covering and protecting catalysts. Light burnt magnesia balls can also be used in hot blast stoves and heating transformation equipment in the iron and steel industry. Light-burned magnesium balls are divided into ordinary light-burned magnesium balls and high-magnesium light-burned magnesium balls. Ordinary light-burned magnesium balls are suitable for converters and converters in the sulfuric acid and fertilizer industries, and high-magnesium light-burned magnesium balls are suitable for urea, steel and other industries. Hot blast furnace, heating conversion furnace and other equipment. Light-burned magnesium is calcined magnesite, brucite and magnesium hydroxide extracted from seawater or brine at about 800~1000°C to decompose and discharge CO2 or H2O to obtain light-burned magnesium powder, also known as light-burned oxidation Magnesium, caustic magnesia or lightly burned magnesia, commonly known as bitter earth powder. Lightly burned magnesium powder is loose in texture and has high chemical activity. It can be used to manufacture magnesium cement, magnesite building materials, heat insulation materials, etc., and is an intermediate product of high-quality magnesia produced by two-step calcination. When magnesite is heated, equiaxed periclase appears around 600°C; equiaxed periclase disappears at 650°C, and non-equiaxed periclase occurs; equiaxed periclase occurs at 850°C Completely disappear. These periclase lattices have high surface energies due to the presence of point defects and dislocations. The lattice of MgO has less water than the lattice group of MgCO3, so the pores between the lattices are enlarged, the porosity is high, the specific surface area is large, and it has high activity. Lightly burned magnesium powder is light yellow, light brown powder, the particle size is mostly below 100 mesh, the periclase crystal is very small (<3μm), the true specific gravity is 3.07~3.22, the bulk density is 0.8~1.2g/cm3, and the refractive index is 1.68~ 1.70, large lattice constant (α=0.4212), many lattice defects, brittle texture, pore structure, high reactivity, easy to undergo solid-state reaction or sintering, and react with water to generate Mg(OH)2 and harden, sticky binding ability. The light-burned magnesia powder calcined from magnesite shrinks by about 5% in volume; usually 3%~5% of CO2 remains due to incomplete decomposition. The light-burning temperature and light-burning time of magnesite have a certain influence on the activity of light-burned magnesium powder. The magnesite was calcined at 600, 650, 700, 750, 800, 850 and 900°C respectively, and the calcination temperatures of 700, 750, and 800°C within 15 to 90 minutes had no obvious effect on the activity of light-calcined magnesium powder; 600, 650, 850, and 900°C have a particularly significant effect on the activity. When calcined at 600, 650°C, the activity increases significantly with time; when calcined at 850, 900°C, the activity decreases significantly with the prolongation of hydrocarbon calcination time. There are many types of light-burned magnesium ball products, high added value, wide application, and high degree of industrial relevance, directly serving many industries in the national economy and various fields of high-tech industries. Vigorously developing magnesium oxide has become the strategic focus of countries all over the world to adjust the structure of the chemical industry, improve the energy level of the chemical industry and expand economic benefits. The ratio of output value to total chemical output value) has become an important symbol to measure the development level of a country or region's chemical industry and the level of chemical technology. Lightly burned magnesia balls are a kind of alkaline refractory product, the function of CaO: it can replace CaO in lime, ensure the basicity of steelmaking final slag, and reduce the amount of lime added. CaO can react with SiO2 in the slag CaO+SiO2=3CaO.SiO2, Ca2SiO4, C3S, and C2S are all high melting point substances. If the CaO content in the slag is sufficient, the main component of the light-burned magnesia ball is MgO. . Although the purpose of reducing the superheat of the slag and thickening the slag can be achieved by adjusting the operation of MgO in the slag, the use of C-O reaction C(FeO)=Fe+CO reduces the content of FeO in the slag and the saturation solubility of MgO, making the slag MgO in is easier to reach or exceed the saturation value. Therefore, the modified slag has both high refractoriness and suitable viscosity, which meets the conditions of slag splashing to protect the furnace, so it can also be properly carburized in light-burned magnesia balls. It is one of the most dynamic emerging fields in today's chemical industry and is an important part of new materials. Strengthening technological innovation, adjusting and optimizing the product structure of magnesium oxide, and focusing on the development of high-performance, specialized, and green products have become important features of the current development of magnesium oxide in the world, and it is also a key direction for the development of magnesium oxide in the world in the future.
Light burnt magnesia ball is made of industrial magnesia and refractory kaolin as the main raw materials through scientific formula, forming and high temperature calcination. It has high mechanical strength and long service life; it has good chemical stability and does not chemically react with materials. Good high temperature resistance, the highest heat resistance temperature of refractory ceramic balls can reach 1900 degrees.
