Improvement of The Ceramic Fiber Module for Saving Top of Tunnel Crown

- Nov 20, 2018-


The sintered tunnel kiln used to be a vaulted roof or a suspended flat roof constructed of refractory bricks, and also a flat roof made of refractory castable prefabricated blocks. 

Both refractory bricks and refractory castable materials are heavy, compared with ceramic fibers, they have the following disadvantages, such as high heat capacity, high thermal conductivity, long construction period and complicated maintenance. Compared with the heavy refractory materials, the ceramic fiber module is light weight and easy to install, which is resistant to the thermal shock, easy maintenance, controllable furnace temperature, it’s a big step for improving the refractory materials.
