Kiln Hood & Cooler

Besides the high thermal stresses in the kiln hood, there are also increasing thermochemical stresses due to using of alternative (secondary) fuels. This makes prioritizing thermochemical resistance essential when selecting the most suitable refractory materials for the hood lining. Given the hood's particularly sensitive behavior during heat-up, it is preferable to use refractory materials that are unaffected by heating. 

Benefits

  • Low thermal conductivity
  • Excellent resistance to abrasion
  • Strong resistance to chemical attack
  • Thermal shock resistance
