What is Spun Ceramic Fiber Blanket

Ceramic Fiber Blanket

Spun ceramic fiber blanket has low thermal conductivity, low thermal capacity, excellent thermal stability and thermal shock resistance, excellent tensile strength, excellent thermal insulation, good fire protection and sound absorption. It can be used in industrial furnaces, heating devices,high temperature pipe lining, industrial high-temperature reaction equipment, heating equipment lining, power boilers, gas turbine, furnace door, and high-temperature filter materials.

The heat capacity of spun ceramic fiber blanket is only 1/10 of that of lightweight refractories lining and light castable refractory material lining. The heat capacity of the lining material is is proportional to its weight. Low heat capacity means less heat absorption of the furnace in the reciprocating operation and higher heating rate. It can greatly reduce energy consumption of the temperature operation control, refractory company especially the start and shutedown of the heating furnace.

Spun ceramic fiber blanket is made of spun ceramic fiber cotton by needling, heat setting, vertically and horizontally cutting and rolling. Ceramic fiber blankets with different thickness and density provide a wide range of choice of materials to obtain the best insulation and energy efficiency.
Spun ceramic fiber blanket has uniform diameter, long fiber and low content of slag balls. Its interleaving degree, delamination, properties, erosion ressitance, flexibility and tensile strength are all improved, which improves the application performance of spun blanket and reduces the material loss. Spun blanket does not contain any binding agent to ensure that products have good reliability and stability in various environments.

Reasons of why tundish dry vibration mix takes the place of tundish insulation board

FiberFrax Duraboard products are rigid, high temperature ceramic fiber boards manufactured in a wet forming process using Fiberfrax alumina-silica fibers and binders. They offer low thermal conductivity, high temperature stability, uniform density and excellent resistance to thermal shock and chemical attack.

Following the clay and high alumina brick, tundish insulation board, tundish coating, Dry vibration mix is the fourth working lining materials for tundish. Following compare shows why dry vibration mix could replace the insulation board successfully.
    Insulation board, which is mainly used in cold tundish (one without baking before being used), it devotes much for us in energy saving and heat insulation. But, due to its fatal disadvantage, it is being eliminated quickly. 
1. Bonded with many agent, insulation board add silica and hydrogen under high temperature in steel liquid, reduce its purity, produce harmful gas to hurt workers health. VS: Dry vibration mix is bonded without carbon, produce no sharp aroma, and greatly reduce avoid the pollution for steel liquid and environment. 
2. Short using life (for common steel, only 8 Hrs, For Mn-alloy steel, only 4hrs). VS: dry vibration mix usual using life: min 24 hrs, when worked with the fast exchange nozzle, it could reach average using life 45hrs.
3. Easy to be broken during transportation, once one piece is broken, the whole set will can not be work. VS: dry vibration is premixed and packaged in waterproof jumbo, applicable for ship, truck, train, air, etc long way transportation. 4. Low corrosion resistance, easy to make tundish become leakage. VS: dry vibration mix is made by ramming, dense and stable, after sintering, form a protect layer with tundish backing layer, could improve tundish using life and reduce spare tundish number.
    Therefore, should you want to improve your tundish life, please do not hesitate to try Changxing Refractory dry vibration mix, 24 hrs using life is waiting for you.
