Introduction of Kerui High Alumina Lining 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.

Video of Kerui High Alumina Refractory Bricks Specification

Kerui high alumina fire brick production line adopts highly automated equipment to achieve efficient production capacity and stable quality. The products have been inspected and highly recognized by many visiting customers. This video presents the product characteristics, intelligent production process, quality inspection links and standardized packaging and delivery system in an all-round way, and intuitively shows the core advantages of the Kerui as the high alumina brick supplier and manufacturer.

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.
