Features of Alumina Silicon Carbide Composite Brick
- High Refractoriness: Alumina silicon carbide bricks have high refractoriness. The under load temperature is more than 1550℃. So they can be used in high-temperature environments and keep a stable volume. In this situation, using this brick as the lining of high temperature can prolong the service time.
- Great Wear Resistance: High alumina silicon carbide bricks have great wear resistance because of the steady chemical structure. The bulk density of Kerui bricks is 2.55-2.65g/cm³. In this situation, the wear resistance of high alumina silicon carbide brick is better than high alumina brick. So they can used for rotary kilns.
- Good Thermal Shock Resistance: Silica mullite bricks contain SiC. SiC has a low thermal expansion that can improve thermal shock resistance. High alumina silica carbide bricks can undertake more than 85MPa in cold crushing strength.
- High Temperature Compressive Strength: Kerui bricks have excellent temperature compressive strength. They can sustain a stable structure in 10 cycles of thermal shock resistance (1100℃, Water Cooling). In this situation, they are used for abrasion parts of high-temperature equipment.
Usages of Silica Mullite Brick
Alumina silica carbide composite brick is used for the ceramic industry, steel industry, and cement industry high-temperature equipment. such as steel wire quenching heating furnaces, cement rotary kilns, particle steel rotary kilns, magnesite incinerators, and sintered mullite rotary kilns. It is also used as the material for making kiln furniture of ceramic firing.
