Fused magnesia is made from high-quality magnesia by melting. Hengyu fused magnesia is made by melting high-quality magnesia as raw material and calcining magnesite, brucite or magnesium hydroxide extracted from seawater at high temperature. Strong hydration resistance.


Fused magnesia is prepared by melting selected super-a natural magnesite or high-purity light burned magnesium particles in an electric arc furnace. Fused magnesia has high purity, large crystalline particles, compact structure, strong slag resistance and good thermal shock stability. It is not only an excellent high-temperature electrical insulation material, but also an important raw material for making high-grade magnesia brick, magnesia carbon brick and amorphous refractory.


It is a general term for the products of magnesite and other magnesia raw materials after high-temperature treatment to the degree of sintering. Magnesia calcined with natural magnesite as raw material is called sintered magnesia by one-time calcination or two-step calcination process with high-temperature equipment such as shaft kiln and rotary kiln; Using magnesite as raw material, fused magnesia is formed after melting in electric arc furnace and cooling; Magnesium oxide extracted from seawater is called seawater magnesia. Magnesia is one of the most important raw materials for refractories. It is used to manufacture all kinds of magnesia bricks, magnesia aluminum bricks, ramming materials, furnace mending materials, etc. Those containing more impurities are used to pave the bottom of steelmaking furnace, etc.
