Refractory Ceramic Fibre

Ceramic Fiber Felt

Applications:

  • Steel industry: the insulation of lining and mold.
  • Nonferrous industry: the pouring of copper and copper-bearing alloy.
  • Ceramic industry: internal lining of lightweight kiln car and furnace.
  • Glass Industry:Tempering Furnace insulating refractory.
  • Kiln construction: refractory material of internal lining (instead of fiber blanket).
  • Light industry: Industrial and domestic boilers combustion liner
  • Petrochemical industry: the lining of high-temperature heating furnace.

    Introduction

    Hengrui ceramic fiber felt is made by wet vacuum forming. The strength of fiber felt is higher than ceramic fiber blanket and lower than ceramic fiber board, and the density is about 220kg/m³, so it can be used in the high-temperature field which has flexible requirements to products.
