Ceramic Fiber


Rongsheng ceramic fiber blanket presents unparalleled refractories and thermal insulation due to its long spun fiber needling technique; these blankets offer superior insulating performance and flexibility. Our ceramic fiber blanket products are unaffected by most chemicals (except hydrofluoric and phosphoric acids and concentrated alkali). Thermal and physical properties are retained after drying following wetting by oil, steam or water. This ceramic fiber blanket products are completely inorganic, so there are no fumes when heating for the first time.


1.Needled blanket.
3.Low density and low thermal conductivity.
4.Shorter heat up and cool down time.


1.Annealing furnaces.
2.Furnace door linings and seals.
3.Soaking pit covers and seals.
4.Furnace hot face repairs.
5.Reheating furnace and ladle covers.
