WHAT’S AM70 fused alumina magnesia spinel 0-1mm
AM70 fused alumina magnesia spinel was made from high-purity light-burned magnesium powder and industrial alumina powder. After smelted by a large high-temperature electric arc furnace, the Fused magnesium aluminate spinel has the characteristics of high density, good appearance, good corrosion resistance and good thermal shock resistance. It inherits the advantages of high melting point and low expansion coefficient, alkali resistance especially alkaline residue from alumina and magnesia. Meanwhile, it avoids the high expansion coefficient of magnesium oxide, poor alkali resistance of aluminum oxide.

APPLICATIONS OF AM70 fused alumina magnesia spinel 0-1mm
AM70 fused alumina magnesia spinel is widely used in the top of steel-making electric furnace, converter , ladle, large cement rotary kiln firing zone, excessive belt and glass regenerator that need alkaline resistance slag, wear resistance and high refractoriness.
AM70 fused alumina magnesia spinel products include magnesium-rich spinel, general spinel and aluminum-rich spinel. Magnesium-rich spinel is mainly used in cement kiln firing zone with periclase spinel brick, over-spinel brick, lithium battery three-way catalysis sag high resistance in alkaline environment; The general spinel is used for corundum spinel castable in ladle, breathable brick, nozzle, furnace lid and other parts; The aluminum-rich spinel, with good alkaline residue and good anti-permeability, is mainly used for high-performance aluminum spinel castable, and the demanding parts that RH spinel brick instead of magnesia-chrome brick.
