High Alumina Refractory Bricks Composition

Cheap High Alumina Refractory Bricks, a kind of alumina-silicate refractory with more than 48% alumina content, is manufactured with bauxite or other raw materials with higher alumina content through molding and firing. High Alumina Bricks have excellent properties of high thermal stability and good slag erosion resistance. Its refractoriness is over 1770℃.

High Alumina Refractory Bricks Properties

  • One of the most important working properties is the structure strength in the high temperature, which is generally evaluated by load softening deformation temperature and high temperature creep.
  • Resistance to spalling and Erosion, high refractoriness under road and good thermal shock resistance.
  • The High Alumina Bricks price is determined according to the bulk density of high alumina bricks. Generally, the bulk density of high alumina bricks is between 2.3 and 2.5 g/cm3. The higher the bulk density, the more expensive the price is. The grade I high alumina brick’s bulk density is required to be 2.4 or more.
  • Refractoriness under load of High Alumina Refractory Bricks with less than 70%. Al2O3 content depends on the quantitative proportion of crystal phase and liquid phase of mullite and will enhance along with the quantity increase of mullite. Quality and properties of liquid have obvious influence on refractoriness under load. Thus lowering the impurity content of raw material will improve refractoriness under load and high temperature creep. And the testing result shows that refractoriness under load will increase along with the increase of Al2O3 content.

Manufacturing Process of High Alumina Refractory Bricks

  • High Alumina Refractory Bricks have the similar manufacturing process with fire clay bricks. Just some technological parameters are different. The process is grinding, mixing, molding, drying, firing, testing and packaging. Compared with clay bricks, high-alumina bricks have a higher firing temperature. For example, the grade I and II high alumina bricks are fired in tunnel kiln at 1500-1600 °C.
  • High alumina refractory bricks perform higher pressure stress in the low temperature, but lower pressure stress in the high temperature. The proportion of clinker can reach up to more than 90%. Clinker before breaking needs to go through selecting and deironing in the higher temperature.
  • The production practice shows that select and grade alumina clinker before breaking and fine grinding methods, which can improve the quality of high alumina refractory bricks.

High Alumina Refractory Bricks Uses

It is mainly used to build blast furnace, hot blast stove, electric furnace top, air furnace, rotary kiln lining. Besides, High Alumina Refractory Bricks also can be used as checker brick of heat accumulating type for open hearth furnace, chock plug for pouring system and nozzle brick.
