China Non-Ferrous Metals Ceramic Fiber Board for Industrial Furnaces factory and manufacturers | Rongsheng

Short Description:

Ceramic fiber board is white and light board which is made by the wet vacuum forming process. The strength of the refractory ceramic fiber board is higher than that of ceramic fiber blanket and the vacuum felt. Ceramic fiber insulation board is suitable for the high temperature field with the requirement of the rigid strength of product. In the petrochemical, metallurgical, ceramic and glass industries, ceramic fiber board is used for backing lining of the furnace.

Ceramic Fiber Board Description

Ceramic fiber board is manufactured and designed for the thermal applications requesting high demands on rigidity, the thermal insulation properties and abrasion resistance of ceramic fiber boards have been further improved due to the higher density. Ceramic fiber board is a vacuum formed product that resists higher gas velocities than ceramic fiber blanket. Refractory ceramic fiber board is ideal for furnace, boiler duct and stack lining thanks to its thermal conductivity and low heat storage, which makes the shorter cycle times and quicker access for maintenance in the industrial furnaces possible.

Properties of Ceramic Fiber Board

  • Light weight,
  • 1260℃ refractoriness,
  • Good wind erosion resistance,
  • Good thermal shock resistance.
  • Accurate size and good smoothness,
  • Low thermal capacity and low thermal conductivity,
  • High pressure resistance and long service life,
  • Even fiber distribution and stable performance.

Manufacturing Process of Ceramic Fiber Board

Ceramic fiber insulation board is a kind of aluminium silicate fire-resisting board, which is manufactured through vacuum forming with quality aluminum silicate wool as the raw material after removing slag and impurity by washing, adding high temperature resistance binder, forcing, mould forming, dewatering and solidifying elaborate processing.

Classification of Ceramic Fiber Board

According to the working temperature and chemical components of ceramic fiber board, whcih can be divided into four types.

  • Ordinary ceramic fiber board (use temperature 1050℃),
  • Standard ceramic fiber board (use temperature 1260℃),
  • High purity ceramic fiber board (use temperature 1260℃),
  • Alumina ceramic fiber board (use temperature 1360℃),
  • Zirconium ceramic fiber board (use temperature 1430℃).
