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. | |
