How much is the wholesale price of Yanbian state fused magnesia manufacturers
Production process of large crystal fused magnesia: large crystal fused magnesia is mainly made by melting 91% - 92% magnesium oxide particles with the size of 0 mm - 3 mm in an electric arc furnace. This product has large crystal grain, compact structure, slag resistance and good thermal shock stability. It is an excellent high temperature electrical edge material and an important raw material for making high-grade magnesia bricks, magnesia carbon bricks and unshaped refractories. It is widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components, etc.

What are the main contents of magnesia? The medium grade magnesia mainly contains 94% and 95%. The medium grade magnesia is produced from light burned magnesia with 97% MgO as raw material through ball pressing, high-temperature shaft kiln calcination and other processes. The product has good sintering degree and dense crystallization. It is a high-quality raw material for producing medium grade magnesia refractory products.

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.

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.
