Magnesia Alumina Bricks-Magnesia Alumina Ladrillos

Product Description:

Israel magnesium stone as the main mineral components of refractory products.According to the raw material of different, can be divided into:
Magnesium aluminum brick
Made of brick magnesia magnesite brick, add a small amount of special grade bauxite or industrial aluminium oxide magnesium aluminum bricks,

graphite powder was added into the magnesia carbon brick, with poor quality of high silica silica magnesia made of magnesium.

Compared with other refractory brick, magnesite bricks of high refractoriness, can reach more than 2000 ℃, has high refractoriness under load, high mechanical strength, and good resistance to alkaline slag containing iron oxide and calcium oxide chemical erosion performance.

But generally poor thermal stability.
Magnesium oxide content in the products is approximately 85%.Alumina content is 5% ~ 5%, the Israeli magnesium stone

as the main crystal phase, magnesium aluminate spinel, for crystal phase (combination as the main phase), alkaline refractory

materials.Porosity is commonly 15 ~ 18%.Thermal expansion coefficient of 10.6 x 10-6 / ℃.Thermal shock resistance than phase
Magnesium aluminum brick
Should the magnesite brick is good.Due to distribution in the matrix which has higher melting point magnesium aluminate spinel and

its high temperature and high strength, load softening starting temperature above 1580 ℃.The slag resistance is better also.

With high quality sintered magnesite as granular materials commonly, join in a certain proportion coordination with alumina raw or

lightly calcined alumina magnesia clinker or industrial alumina powder, by mixing, molding and firing system.
