Application of Magnesia Zirconia Brick
Magnesia zirconia bricks find wide applications in high – temperature industrial sectors. In steel – making converters, they line the walls, enduring high – temperature molten steel and slag. In glass – melting furnaces, these bricks resist the corrosion of high – temperature glass melts and combustion gases. They’re also used in cement kilns, protecting the kiln structure from intense heat and chemical attacks, thus ensuring long – term, stable operation of these facilities.
Advantages of Magnesia Zirconia Brick
1.High refractoriness, enabling them to endure extremely high temperatures in harsh environments. 2.Good slag resistance, effectively resisting the erosion of various slags. 3.Excellent thermal shock stability, maintaining integrity under thermal stress. 4.High mechanical strength, capable of withstanding heavy loads and impacts.
