Introduction of Kerui High Alumina Refractory Brick

  • Raw material: Kerui brick is a neutral refractory material with more than 48% content of Al2O3. The main raw materials are alumina clinker and bonded clay.
  • Burning temperature: The high-quality raw materials are burned between 1500-1600°C and form bricks.
  • Quality control: Kerui has a strict quality control system, including raw materials quality testing, quality reports of high alumina bricks, etc.
  • Production equipment: 400T-1000T presses, 2*168-meter natural gas tunnel kilns, etc.
  • Features: It has high thermal stability. The fire resistance is above 1770 °C.
  • Uses: The residual resistance is better, and it is used in the lining of the steelmaking electric furnace, glass furnace, and cement turning furnace.
  • Shapes: Besides standard size (230*114*65mm), Kerui offers side-arc shape, side-arc shape, anchor brick, arc brick, etc.

Different Sizes of Kerui Refractory Bricks

Advantages of Kerui Alumina Refractory Bricks

  • High refractoriness: The refractoriness is as high as 1750-1790 degrees Celsius.
  • High load softening temperature: The high alumina content and low impurities make the load-softening temperature higher than that of fire clay brick.
  • Strong slag resistance: Alumina can well resist acidic and alkaline slag.
  • Strong thermal shock resistance: The thermal expansion coefficient is low. It is not easy to deform at high temperatures.
  • Strong mechanical properties: High alumina refractory bricks can better withstand compressive and flexural strength.
