Features of refractory fibers

1. High temperature.

The highest use temperature up to 1250~2500 DEG C. The most commonly used asbestos only 500~550 DEG C, slag wool is 580~830 DEG C, and aluminum silicate fiber above 1000 degrees.

2. Heat capacity is low.

Refractory fiber under high temperature heat conduction ability is very low, such as 1000 DEG C, conductivity of aluminium silicate fiber is only 20% light clay brick, clay brick 38%.

3. Small volume density.

Usually 0.1~0.2g/cm fand, general clay brick for 1/20~1/10, 1/10~1/5 light clay brick. Therefore, application of refractory fiber industrial furnace instead of refractory bricks, which can make the furnace body weight, furnace wall thickness. If the heating furnace using fiber lining reduces 80%, furnace wall thickness of 50%.

4. Good chemical stability.

In addition to alkali, fluoride, sulphate, erosion is almost unaffected by chemicals.

5. Good thermal shock resistances.

Both fiber materials and products of refractory brick, has the incomparable good thermalshock resistance.

6 low thermal capacity.

1/72 heat capacity of the fiber material only refractory brick, light clay brick 1/42.Refractory fiber lining for storage, loss is small, fuel saving, fast temperature rise, the intermittent operation furnace affection is obvious.

7. Soft, easy processing.

Can be made into a variety of products and personnel shape parts, construction is convenient, the labor intensity is low, the effect is good.
