  • Main benefits:
    • high temperature operating mode;
    • efficient energy saving;
    • stable operation in a variable temperature range;
    • strength under mechanical stress (compression, bending, pressure);
    • resistance to open fire and negative environment (acid, alkali).
    Examples of using:
    • fireproof protection of industrial furnaces, boilers and chimneys;
    • insulating material in fire protection systems and power grids;
    • as a heat insulator for steel-pouring ladles and equipment for the transportation of liquid aluminum.
  • Refractory boards provide industrial equipment with the possibility of long-term operation at high temperatures. The heat-resistant board based on ceramic fibers is of that kind. At a peak temperature of 1430 C and prolonged heating within 1350 degrees, it is reliable in operation, withstands thermal shocks and stably retains its strength. That way the density indicator of 300 kg / m3 remains unchanged and the heat capacity and thermal conductivity are generally low. The linear shrinkage of the material after 24 hours of heating is even lower. It is less or equals to minus 3%.

    Rigidity, elasticity, strength, structural homogeneity of a heat-resistant board is achieved, among other things, due to the homogeneous distribution of ceramic fibers. Precise measurements and a smooth surface simplify the installation process and reduce labor costs.

    Type: a refractory board

    Installation and operation manual for ceramic fiber boards

    First-time heating properties and the use of boards for lining.

    Ceramic fiber boards contain a small percentage of organic and inorganic binder. Therefore, in the process of the first-time heating, when the temperature of the board rises up to 200-300 C, the organic binder burns out, followed by intense smoke emission, a loss of mass up to 5.5% and a strength reduction of the board to 50-60% (this is the case for unpolished boards and observed only during the first-time heating). When the temperature reaches 800-900 C and above, the inorganic binder hardens and, as a result, the board material hardens up to 80% of the initial strength. Therefore, when using boards as the first (working) layer of lining, the temperature of the board body should not be lower than 900 C.

    In addition, at a working temperature close to the maximum, the boards are prone to linear shrinkage up to 3%, which must be taken into account when designing and installing the lining, by using heat shrinkable joints between individual elements. Heat shrinkable joints are made of ceramic fiber blankets of the appropriate temperature of use. The blanket with a thickness of 12.5 mm (density 128 kg / m3) is doubled and compressed during installation up to 10-12 mm (for the dimensions of the mounted boards 1200x1000 mm). When using boards as a compensation or heat-insulating layer (at a layer temperature of less than 900 C), heat shrinkable joints are not installed.

    Fastening boards during installation.

    • During installation, the boards are glued to the surface of the framework or the previous layer with heat-resistant adhesive for ceramic fibers (the temperature of use is not lower than the temperature of use of the boards). To obtain a layer of more than 50 mm, the plates are glued together using a heat-resistant adhesive for ceramic fibers.
    • The boards in the lining layer are attached to the framework with anchors and washers made of heat-resistant steel (the heat resistance of the steel should correspond to the temperature of the lining layer with the boards). The dimensions and spacing of the anchors are determined by the project (at least 9 pieces per board 1200x1000 mm).

    The design of the anchors, washers, and their fastening is determined by the project in each specific case.
