Application of refractory ceramic fiber products in ceramic kiln

As a kind of high temperature insulation material, various refractory ceramic fiber products have been used more and more in high temperature industrial furnaces at home and abroad. The application of ceramic fiber lining in various industrial furnaces can save energy by 20%-40%. The physical properties of the refractory ceramic fiber products reduce the masonry weight of the industrial kiln, the construction is simple and convenient, the labor intensity is reduced, and the work efficiency is improved.

Application of refractory ceramic fiber products in ceramic kiln

(1) Filling sealing material

The expansion joint of the kiln, the gap between the metal parts, the hole at the rotating part of the roller kiln, the joint of the ceiling kiln, the kiln car and the joint can be filled or sealed with refractory ceramic fiber products.

(2) Outer insulation material

Ceramic kiln mostly uses loose ceramic fiber bulk or ceramic fiber felt (board) as thermal insulation material, which can reduce the thickness of kiln wall and reduce the surface temperature of kiln wall; the fiber itself has elasticity and filling, which can alleviate the thermal stress of brick wall expansion. Improve the air tightness of the kiln; the heat capacity of the fiber is small, which is helpful for rapid firing.

This issue we mainly introduced application of refractory ceramic fiber products in ceramic kiln as filling sealing material and outer insulation material. Next issue we will continue to introduce other application of refractory ceramic fiber products in ceramic kiln.
