The appropriate refractory selection for the stationary section improves the kiln uptime, which, in turn, has favourable impact on the refractory life as well as operating efficiency, says I N CHAKRABORTY.
Refractory selection is the most important step for the maximisation of its performance. The major deciding factor for refractory selection is the working or operating environment where the refractory would be used.
The working environment, in general, is defined by the following parameters:
