Product Details

Features:

1.Low thermal conductivity, relatively dense stomatic distribution has good heat insulation effect,

2. low thermal conductivity, efficient and energy saving. High strength: hot high crushing strength,

volume stability is good.

3. Low thermal capacity: in the case of absorb more heat, brick itself very little heat, energy saving

effect is obvious.

4.Low impurity content, has a very low iron and alkali metal melt less impurity in low temperature.

5.High dimensional accuracy, mechanical processing molding,

6.High precision and can be processed into special shape, speed up the building.

Advantage:

1. Industrial furnace masonry regenerative losses and furnace surface heat loss, generally accounts for about

24 to 45% of the fuel consumption.With low thermal conductivity, low thermal capacity of lightweight brick

for furnace construction materials, can save fuel consumption;

2. At the same time, because of kiln can be rapid heating and cooling, can improve the efficiency of production

equipment;

3. Also can reduce body weight, simplify the kiln structure, improve product quality, reduce the environment

temperature, improve working conditions.

USES:

1. Metallurgical industry: the blast furnace, blast furnace hot blast stove, heating furnace, etc.

2. Petrochemical industry: ethylene cracking furnace, hydrogen furnace, a furnace, furnace, etc.

3. Ceramic industry: roller kiln, push board kiln, etc.

4. Industry: glass kiln heat storage room, etc.

5. Carbon industry: carbon calciner, etc

6. Aluminum electrolytic industry: aluminum electrolytic tank, etc.

7. Other industries: tunnel kiln, shuttle kiln, etc
