In the previous period, we introduced the four issues in the use of alumina silicate refractory fibers - high temperature make aluminum silicate refractory fiber powder, harmful gases erosion to make alkali silicate fibers shrinkage, and air scour the fiber shedding, as well as displaced installation and wrong material.

     For fire-resistant fiber application on brick kilns, we especially raise the following recommendations:

     A.About choosing the refractory fiber material, we'd better choose models and specifications of refractory fibers according to the characteristics of local raw materials. when sulfur content of the feed stock is relatively high in brick's raw material, the best choice is high-alumina refractory fiber or composition refractory fibers.

     B. In the kiln calcination zone, we should use high-alumina refractory fiber, and spray 1mm thick energy-saving high-temperature coating fibers in refractory fiber surface; low temperature zone can use ordinary refractory fibers. Regardless of the high temperature zone or low-temperature zone,we must ensure that the laying of 3-5mm thick steel panel on steel structure, and anchoring nails must be firmly welded to the steel panel, in the seam time,refractory fiber lining's thickness must guarantee more than 300mm, and the performance indicators must meet the standard requirements.
