Magnesia Alumina Spinel Brick

Magnesia alumina spinel brick is made of magnesia alumina spinel, magnesia alumina spinel bricks are in order to improve the heat stability of magnesia brick, based on magnesia bricks, add alumina oxide in ingredient. Magnesite alumina spinel brick has the advantages of good heat stability, in the process of use, magnesia alumina spinel firebrick will have reaction with clinker and produce a thin layer of calcium aluminate maskant, which makes the liquid not easy to penetrate, magnesia alumina spinel refractory brick anti stripping performance is better than the direct bonded magnesia chrome brick.

Magnesia Alumina Spinel Brick Description

Magnesia alumina spinel firebrick is a magnesia brick with magnesium aluminum spinel as the main mineral formed by adding alumina to the furnish to improve the thermal stability of the magnesia brick. Magnesium alumina spinel fire brick is made of high quality magnesia with low calcium content and industrial alumina powder. magnesium alumina spinel firebrick is formed by high pressure forming and high temperature firing. Magnesia alumina spinel refractory brick has good resistance to quenching and heat, Magnesia alumina spinel firebricks has good corrosion resistance to fluxes such as iron oxides and alkaline slag.

Properties of Magnesia Alumina Spinel Brick

.High melting temperature,
.Low thermal expansion,
.Good thermal shock resistance,
.Good anti-stripping capacity,
.High temperature strength,
.Volume stability.

Manufacturing Process of Magnesia Alumina Spinel Brick

The main impurity in magnesium alumina spinel bricks is SiO2, which should not exceed 1.5%. The advantage of magnesia alumina spinel is that it has good thermal shock resistance. During the process of use, it reacts with clinker to form a thin layer of calcium aluminate protective layer on the surface of the spinel brick, magnesia alumina spinel refractory brick makes the liquid phase difficult to penetrate and resists peeling performance.

Advantage of Magnesia Alumina Spinel Brick

Advantage of magnesium aluminate spinel brick is good thermal stability, will react with clinker in the process of use, and then on the surface of brick form a very thin layer of calcium aluminate layer, bauxite sintering magnesium aluminum spinel using Al203 content more than 76% of the high quality bauxite and the content of MgO style more than 95% of the light burning magnesium powder with high quality.

Application of Magnesia Alumina Spinel Brick

The magnesia alumina spinel brick can be used in the cement kiln, not only avoid the chrome pollution, and has good anti stripping performance. magnesia alumina spinel refractory brick is widely applied to steel making refractory material. The preparation of high quality pre synthertic spinel provide a new material for amorphous and fixed high purity refractory. Also magnesia alumina spinel firebrick can be used in refractory carstables for ladles, which greatly improve the anti erosion ability.
