Introduction of Kerui Magnesia Refractory Bricks
The main raw material of Kerui magnesia bricks is magnesia (MgO), with a content as high as 91%. Meanwhile, it has high refractoriness at 2000℃ (3632℉) and strong resistance to alkaline corrosion. Besides, Kerui offers large-scale magnesite refractory bricks for sale continuously. Addtionally, according to different manufacturing processes, Kerui magnesium brick can be classified into burnt refractory brick and unburnt refractory brick:
Burnt Magnesia Refractory Bricks
Burnt magnesia brick needs sintering process with high temperatures to combine particles in the bricks tightly. Therefore, this brick has higher density and durability. Generally, burnt magnesia in brick includes magnesia refractory brick, magnesia chrome brick, magnesia calcium brick, magnesia alumina spinel brick, magnesia iron brick and so on.
Unburnt Magnesia Refractory Bricks
Unburnt magnesia brick adapts chemical or physical reactions to form a dense structure. Meanwhile, it has a shorter production cycle and lower magnesite bricks price. Commonly unburnt magnesia brick includes magnesia carbon brick, alumina magnesia carbon brick, alumina silica carbon brick, magnesia calcium carbon brick and so on.
Magnesite Bricks Manufacturing Process
Features of Kerui Magnesia Refractory Bricks
As the main content of magnesium brick, MgO has high melting point, which results in high refractoriness. Besides, Kerui factory is located in Xinmi City, Henan Province, it owns rich mineral resources for refractory materials. Therefore, Kerui magnesia bricks properties have superior perforance.
Flexible magnesia brick can be cut and installed easily to fit various complex shapes and structural needs. Besides, magnesite bricks are relatively lighter than other refractory bricks, which is convenient for workers to carry and operate. Therefore, you can contact Kerui to customize magnesia brick to save your time and energy on cutting.
Kerui magnesia brick has strong thermal conductivity. Meanwhile, this means that magnesite bricks is able to absorb and release heat quickly, which improves working efficiency and heat energy utilization. Additionally, by using magnesia fire resistance brick in your kilns, the heat can spread soon and reduce energy consumption.
Compared with magnesia refractory bricks from other suppliers, Kerui’s brick uses better raw materials and more advanced production technology. Therefore, Kerui magnesium brick is harder and has higher density. At the same time, customers who invest in Kerui magnesium brick can reduce the frequency of replacement.
