Medium grade magnesia is produced from light burned magnesia by ball pressing, high-temperature shaft kiln calcination and other processes. The product has good sintering degree, dense crystallization, and the magnesium content is mgo-95%. The use of medium grade magnesia is: it is used to produce magnesium soldering bricks, medium grade magnesia bricks, magnesia castables and other amorphous refractories, and it is a high-quality raw material for magnesia refractory products.

Energy saving refractory is a new industry, which is an industry integrating new technologies to adapt to the transformation of people's consumption structure. The development of energy-saving refractory industry is in line with the world trend. People need fresh air, clean water, pollution-free food, and a good living environment. This is the fundamental reason and driving force for the development of energy-saving refractory industry

Magnesia produced by smelting magnesite in an electric furnace at 2750 ℃ is called fused magnesia. Generally, it has very strong high temperature resistance, is not easy to be melted by alkaline substances, is not easy to be eroded by molten metals at high temperatures, and has excellent thermal conductivity at room temperature. The high refractory carbon magnesia brick (composed of graphite and fused magnesia) made from it as raw material is widely used in converter steelmaking and secondary refining. The smelting cycle is shorter, the furnace life is longer, and the quality of steel is improved.

A magnesium industry person in the northern region said that the transaction situation in the magnesium market was normal last week. As soon as there was a supply of cash including tax of 15500 yuan/ton in Fugu area, it would be quickly accepted. At present, there are few factories in stock. The person looked at the magnesium market this week. A general manager of the magnesium powder factory also said that the factory has few stocks, and the current procurement generally needs to wait for 3-5 days to pick up the goods. This person also believes that the magnesium market is not affected by the ferrosilicon market at present. Although the ferrosilicon market is stable and weak, the magnesium market is unlikely to decline. However, due to the impact, some downstream users of magnesium also use less magnesium, and the magnesium market has insufficient upward momentum under the condition of few orders.

Magnesite is magnesium oxide, which can be made from magnesite, brucite, dolomite, serpentine, olivine and other minerals. Generally, magnesite and brucite can be used as raw materials to calcine and decompose into magnesium oxide, which crystallizes differently due to different calcination temperatures. The magnesium oxide calcined at 600-1000 ℃ is called active magnesium oxide, and the magnesium oxide calcined at 1400-1800 ℃ is called dead burned magnesium oxide. The above two kinds of magnesium oxide are also commonly called light magnesium oxide, commonly known as furnace magnesia.

Magnesite is calcined at high temperature from magnesite, bischofite or magnesium hydroxide extracted from seawater. It is a general term for the products of magnesite and other magnesia raw materials that have been treated at high temperature to reach the sintering process. Magnesite sintered from natural magnesite is made by one-step or two-step calcination process with high-temperature equipment such as shaft kiln and rotary kiln; Seawater magnesia is produced by extracting magnesium oxide from seawater after magnesite and other raw materials are melted in an electric arc furnace and cooled.
