Ceramic Fiber Blanket
Raw material introduction & parameters
The aluminum silicate spining fiber blanket is made of standard fiber cotton and zirconium fiber cotton produced by the fiber spinning process, which are made by needling, heat setting, cutting coil and other technics..etc
Alumina fiber blanket is made by soliquid process to prepare high-purity flexible alumina fiber substrate. After special spraying and wire drawing process, uniform continuous fibers are prepared, and then processed by needle heat treatment, cutting and rolling.
Application Field
Widely used in steel heat treatment furnace
Refractory layer of various low temperature furnace types
Insulation layer of various types of high temperature furnace
