Alumina Silica Refractory Brick

Alumina silica refractory brick is a type of acid-resistant and alkali-resistant refractory material. It is mainly made of silicon dioxide, which is as high as 94%. They have high refractoriness, high load-softening temperature, and stronger slag resistance, thermal shock resistance and mechanical properties than other refractory bricks. It is widely used in kiln linings, pipelines, etc.

  • Bulk Density: 2.3-2.6g/cm³;
  • Flexural Strength: 7-9MPa;
  • Compressive Strength: 40-70MPa;
Kerui Alumina Silica Refractory Bricks

Alumina-silica refractory bricks are a type of refractory brick made by firing a mixture of Al2O3, SiO2, and additives. According to the composition content of alumina and silicon oxide, Kerui Refractory offers the following types of alumina-silica refractory bricks:

  • High Refractoriness: Alumina silicate firebricks have a high melting point, making them suitable for various high-temperature industrial applications.
  • Wear Resistance: Alumina silica fire bricks can be used in environments with high mechanical strength. This kind of silica firebrick have high wear resistance.
  • High Strength: At high temperatures, alumina silicate refractory bricks do not easily fall off. They have strong compressive and flexural strength.
  • Corrosion Resistance: It can resist the corrosion of acidic and alkaline media at high temperatures.
  • Strong Thermal Shock Resistance: Alumina silica firebrick do not deform at high temperatures and maintain their dimensional stability.
  • Good Thermal Conductivity: It can improve the thermal efficiency of kilns and other high-temperature equipment.
