Description of Magnesia Aluminum Brick
Magnesia Aluminum Brick is a magnesia refractory brick product derived to improve the thermal shock resistance of magnesia bricks. The magnesium-aluminum brick is made by introducing alumina or bauxite clinker fines into the ingredients of the magnesium brick to form a magnesium-aluminum spinel matrix. Magnesia brick is a kind of magnesia refractory products with magnesite as the main crystal phase and magnesia-aluminum spinel as the matrix, which belongs to alkaline refractory materials.
Characteristics of magnesia-aluminum brick
Good thermal shock stability
Magnesium-aluminum bricks have good thermal shock resistance, can withstand rapid temperature changes caused by heat, force, chemical reactions and other factors, not easy to crack and fracture phenomenon.
Strong erosion resistance
Mg-Al brick belongs to alkaline refractory bricks, it also has good resistance to slag, can resist the erosion of slag and alkaline substances.
Good thermal conductivity
Magnesia-aluminum brick bricks have good thermal conductivity, which can quickly transfer the required heat to ensure the normal operation of high-temperature devices.
Strong abrasion resistance
Magnesium aluminum bricks have excellent abrasion resistance and are able to withstand heavy pressure and abrasion, and are used under heavy-duty conditions.
Applications of magnesium-aluminum bricks
Steel industry
MgAl bricks are widely used in steel ladle, steel liquid reinjection tube, electric furnace roof, air vent, package lining, five electric field and other parts, which play a role in protecting the furnace lining.
Glass industry
Magnesium-aluminum bricks are widely used in glass furnaces, which can improve the quality of glass products.
Cement industry
Magnesia-aluminum bricks are also widely used in cement rotary kilns.
Refractory industry
Magnesium-aluminum bricks are also used in the refractory industry in equipment such as firing kilns and heating furnaces.
