Application of refractory materials for mid-range magnesia kiln

Data of mid-range magnesia, aluminum silicate, cotton and other kiln refractory materials. These data have high temperature resistance, but they are not easy to transform after high temperature oxidation. The conflict loss is large, the acid and alkali need to be stopped for a long time, and the personnel loss during the construction week is large. Now there are kiln lining protective coatings, which have high fire resistance, high temperature resistance and high oxidation resistance. They are sprayed on the surface of various refractory materials to protect the formation of refractory materials and avoid oxidation and powdering of refractory materials. . Normal wear such as abrasion. 96 Fused Magnesia

The addition of metal to the prediction of refractory materials has a vivid impact on the mechanical properties of fireproof materials and the ability to prevent oxidation, indicating that metals have good application prospects in the prediction of fireproof materials. Due to the better and better development of science and technology and breakthroughs in the field of science, the functions of metal fireproof materials will continue to be optimized, and their application plans will be further expanded. The steel plate or hardwood, steel plate paint (oil), waterproof paint, wood board should have no leakage and have good strength.

High melting point, alkaline refractory materials are widely used in metallurgy, glass, cement, household appliances, heaters, temperature chemicals and other industries. This is not only because the melting point of magnesium oxide is 1,800 degrees Celsius, but also because of its high oxide content, its basic resistance to alkaline oxide slag and high-performance chemical corrosion. Fused magnesia refractory is one of its advantages. Extending the service life of the furnace has a very important role. Fused magnesia is widely used in domestic and foreign markets.

Its characteristics are based on various magnesia obtained from various kilns, molten magnesia scales produced by furnaces, and calcination methods above 600℃ as data, or any mixture as data, or the above data is divided into concentric and concentric Concentric ring loading or raw meal. Graded data (or mixed data). In order to concentrate and use magnesium ore for roughing, a concentric loading species ratio is imposed on the magnesium ore. The existing fused magnesia or griddle furnaces are used for drilling and separation, and the purity may exceed 96.5%.

Medium magnesia is mainly used to manufacture high-grade alkaline or amorphous refractories, and its products are mainly used in metallurgy, building materials, non-ferrous metals, chemical industries and other industries. In metallurgy, other medium magnesia is used to make metallurgical powder combined with furnace bottom and furnace wall to make mud-blasted furnace lining: manufacturing magnesia bricks and magnesia chrome bricks, in addition to being used as furnace bottom linings, it can also be widely used in electric furnace steelmaking and heating furnaces Wait. Stoves, non-ferrous metal blast furnaces, rotary furnaces.
