Magnesium oxide desulfurization technology with high-speed rail and high-calcium sand has been used all over the world. During this period, more than 100 projects have been used in 13 books. 95% of power stations in Taiwan use the magnesium oxide method. It has been used, and it has been implemented in our country, and it has been used in a few areas. Compared with calcium desulfurization, magnesium oxide desulfurization avoids a series of problems in the simple wet process, such as pipeline blockage, low flue gas temperature, water in flue gas, and secondary water pollution; the maturity of the process is only Second to the calcium method, the structure is simple, the area is small, the source of materials is sufficient, the operating cost is low, the performance is good, the investment is greatly reduced, and it can reduce the secondary pollution, the desulfurization agent is recycled, the desulfurization cost is reduced, and the economic benefits are summarized. Get a great progress.

Magnesia is one of the important materials of refractory materials, used to manufacture various magnesia bricks, magnesia alumina bricks, ramming materials, repairing materials, etc.; it is divided into three categories: sintered magnesia, light burned magnesia, and fused magnesia. The calcination of natural magnesite may be fused, refined from sea water, salt lake brine, and refined from dolomite, serpentine and brucite. The mid-grade magnesia is made of light-burned magnesia with 97% MgO content as the raw material, and is produced by processes such as ball pressing and high-temperature shaft kiln calcination. With the advancement of science and technology, light-burned magnesia powder can be used in a wider range of applications. It can be used for civil engineering products, light and heavy machinery packaging boxes, packaging bottom beams, high-temperature refractory materials, and it can also produce beautiful and elegant furniture with strong gloss. It can be used in the machinery industry. Cast model.

High-speed iron and high-calcium sand

Magnesia is one of the important materials of refractory materials, used to make various magnesia bricks, magnesia alumina bricks, ramming materials, repairing materials, etc. Containing more impurities, it is used for paving the bottom of steelmaking furnace.

The main component of magnesia is magnesium oxide, and impurities are CaO, SiO2, Fe2O3, etc. Magnesium oxide is an alkaline oxide with a melting point of 2800 degrees. After high temperature heating, it transforms into stable cubic crystals, commonly known as periclase. It is calcined from magnesium hydroxide at high temperature and has strong hydration resistance.

Material origin/magnesia

The calcination of natural magnesite may be fused, refined from sea water, salt lake brine, and refined from dolomite, serpentine and brucite. At present, my country mainly obtains magnesia from magnesite calcination or fusion, while Japan and Western European countries mainly extract it from seawater.
