Product Introduction
Ceramic Fiber Modules are made from ceramic fiber blanket stacked with cut edges exposed, and anchor systems to enable quick, easy and efficient installation in most furnace linings. These prefabricated modules are designed to meet the thermal insulation requirements of high temperature furnaces.
Features
1.Low thermal conductivity. 2.Good thermal shock resistance. 3.Excellent chemical stability.
Application
It can be used in heating furnace and cracking furnace in Petrochemical industry,annealing furnace and roller hearth furnace in metallurgical industry,soaking furnace, homogenizing furnace in aluminum industry,tunnel kiln, intermittent kiln and calcining kiln in ceramics industry.It can also be used for waste gas recovery, combustion chamber.
