Does anyone know the price of light burned magnesia and light Magnesium Oxide?

Release date:2017-11-09 Author: Click:

Magnesia powder is made of light burned oxide powder and pressed by ball pressing machine. The product is uniform in grain size, high in mechanical strength, good in living, easy to decompose and melt in high temperature slag and easy to operate. It is an ideal slag regulating material for slag splashing for converter slag protection furnace, which is mainly used as a component regulator of slag protection in slag splashing furnace for converter. Because slag splashing is required for slag to have proper viscosity and refractoriness, reasonable slag composition is the key to slag splashing. The slag can not be directly carried out in a splash furnace. A certain amount of Magnesium Oxide ball should be added to adjust it, and the use of dolomite can be replaced, and the amount of slag can be reduced and the content of MgO in the slag is increased. Since MgO is a high melting point mineral, the melting point is 2800 C and the content of MgO in the slag is improved, the slag viscosity becomes larger and the refractory degree is increased. The slag is more easily combined with the furnace lining, and the effective slag protection layer is formed on the lining, thus improving the life of the furnace lining and reducing the consumption.

Light burned magnesia

20-60 slag agent is a metallurgical auxiliary material to remove slag from the furnace wall. The principle of its slag is as follows: 1. It consists of some low melting points and substances that can dissolve solid oxide, melt into the molten iron in the molten iron, dissolve the slag and dissolve the slag, and make the slag separated from the wall. 2, at high temperature, the chemical reaction in the slag agent produces a chemical reaction of the slag to produce a low melting point compound. The purpose of converting slag. Using the method: when the molten iron surface reaches the middle of the slag, the slag agent is 1 ~ 2T and the slag agent is melted. The slag is sloshing up and down, so that the slag agent is fully reacted with the slag, and the scour force produced by the sloshing iron water is used to separate the slag from the furnace wall, and the slag can be separated when the slag is heavy. Fruit. At the same time, it should be noticed that the slag agent also has a certain erosion effect on the lining of the refractory. It must be confined to the range of slag when the furnace is shaking, and should be stopped when the slag reaches a certain strength, so as not to damage the lining and reduce the life of the furnace. The amount of the furnace is generally 1 ~ 2T, and the volume of the furnace and the condition of slag hanging are determined. . Physicochemical index: borate with B2O3 meter

When the magnesite is heated, the ISO - ISO - calfite appears at about 600 degrees C, and the ISO - axis of the calfite disappears at 650, and the ISO - axis of the calfite disappears completely at 850. The lattice of these calcite appears to have higher surface energy due to punctate defects and dislocations. The lattice of MgO is less than that of MgCO3 lattice group. Therefore, the interlattice porosity increases, the porosity is high, the specific surface area is large, and the activity is high.

The light burned magnesia powder is yellowish yellow and light brown powder, most of the grain size is below -100 mesh. The crystal of periglite is very small (< 3 m), it has a true specific gravity of 3.07~3.22, the accumulation density is 0.8~1.2g/cm3, the refractive index is 1.68~1.70, the lattice constant is large (alpha =0.4212), the texture is brittle, the structure is large, the reaction activity is large, and the solid phase is easy to carry out solid phase reaction. Should be or sintered, water and Mg (HO) 2 will be hardened and bonded. Light burned magnesia powder calcined from magnesite has a shrinkage of about 5%, usually due to incomplete decomposition of 3%~5% with CO2.

The light burning temperature and light burning time of magnesite have certain effect on the activity of light burned magnesia powder. Calcined magnesite was calcined at 600, 650, 700, 750, 800, 850 and 900 centigrade respectively. The calcining temperature of 700, 750 and 800 in 15~90 minutes had no obvious effect on the activity of light magnesia powder. The activity of 600, 650, 850 and 900 was particularly significant. The activity of calcined at 850 and 900 degrees decreased significantly with the prolongation of hydrocarbon burning time.


The light burning magnesium is made of magnesite, calcined by light burning reflex kiln, rotary kiln or boiling furnace. The product is calcined evenly, the quality is stable, the purity is high, and the activity is good. It can be widely used in paper making, chemical industry, rubber, medicine, animal husbandry, fireproof materials.
