Special Shape alumina refractory bricks Resist 1300 ℃ /refractory brick refractory high alumina brick
refractory brick refractory high alumina brick 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, refractory brick refractory high alumina brick is a kind of essential refractory for energy saving and temperature preservation
refractory brick refractory high alumina brick can resist 1500 ℃ high temperature as well as keep good state, refractory brick refractory high alumina brick also can resist compressive strength of at least 80Mpa, along iwth more than 30 times shock resistance (water cooling).
refractory brick refractory high alumina brick is an ideal insulating refractory refractory material, with advantages of high strength, low thermal conductivity, good insulation property and low price. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
