Product Introduction：
Refractory fire brick for kiln and furnace is a kind of insulation
material adopting organic matter as ignition loss substance in order to
increase the porosity of refractory, which has such advantages as high
porosity, small volume density, good insulation effect, high mechanical
intensity, small thermal conductivity and long service life. For various
industrial kilns & furnaces, it is a kind of essential refractory
for energy saving and temperature preservation.
Feature：
1.Low coefficient of linear expansion
2.Low thermal conductivity,
3.Strong resistance to the acid slag erosion,
4.Excellent thermal shock resistance,
5.High Refractoriness under load,
6.Low high-temperature creep rate.
