Comprehensive protection of the metal jet from oxidation
23.05.2017
The module and block of ceramic fiber acquires a certain density as a result of bending and compression of the ceramic blanket. Their use simplifies and speeds up the construction (installation of lining, etc.) of furnaces and improves the monolithicity and integrity of the lining, reduces the metal consumption of the lining structure. Fixings of ceramic modules and blocks vary in shape.
The white ceramic fiber modular blocks have exact geometric dimensions and are ready to install. They are attached directly to the steel structure of industrial furnaces with the help of fastening devices. They have excellent fire-resistant and heat-insulating properties. The use of ceramic modular blocks increases the monolithicity of the heat-insulating layer of furnaces and speeds up the installation process.
Features and benefits
Application
Modular blocks made of ceramic fiber are used as linings in various industrial furnaces and thermal units in the fields of metallurgy, petrochemicals, mechanical engineering, building materials, etc.
