magnesite alumina brick is a kind of alkaline refractory product with perriclase as main phase magnesia alumina spinel clinker as basic material .magnesia alumina firebrick has such characteristics as good temperature vibration, good strength and volume stability in high temperature. magnesia alumina refractory brick has characteristic of good thermal shock resistance, high refractoriness under load, load softening temperature above 1580 ℃, the glass erosion resistance is good. Which can be used in wide used in the domestic and overseas cement projects.
Properties of Magnesia Alumina Bricks
- Outstanding resistance to chemical attack
- Outstanding thermal-shock resistance,
- Highest refractoriness,
- Excellent abrasion resistance,
- Excellent performance under thermal and mechanical loads.
Manufacturing Process of Magnesia Alumina Bricks
Magnesia alumina firebrick mainly use magnesia alumina spinel as matrix. In order to improve the thermal shock resistance of magnesia brick, fine powder of alumina or bauxite clinker is introduced in the batching to form magnesia alumina spinel matrix. Magnesia alumina fire brick has characteristic of good thermal shock resistance, high refractoriness under load, load softening temperature above 1580 ℃, good glass erosion resistance.
Composition of Magnesia Alumina Bricks
Magnesium alumina fire brick is a kind of spinel basic refractory contains about 85% MgO and 5% ~ 10% Al2O3. The crystalline phase of magnesium alumina firebrick is mainly composed of square magnesia stone and magnesia alumina spinel. The spinel aggregates after crystallization to form a crystal network, which makes the masonry structure compact.Because when making, do not use the aggregate of bulky granule, whole brick body structure is even, stoma disperses.
Packaging of Magnesia Alumina Bricks
1.On wooden pallets with plastic cover: wooden pallet size :930*930 or 1000*1000mm,
2.Load weight of each pallet: 1.5-2.0 tons,
3.230*114*65mm:512PCS/Pallet, 230*114*75mm:448PCS/Pallet.
