Refractory lining structure generally consists of wear layer and insulation layer, however the high temperature equipment like the hot air valve of pipe and the wind blowing pipe in Blast Furnace does not have construction conditions for double lining structure, It requires a kind of refractory material with wear resistance and heat insulation, and also with good air tightness, high temperature toughness and high temperature bulk stablilty. This material has to resist the scouring and erosion of smoke with high temperature and high pressure.
We sincerely cooperate with scientific reserach institutions and successfully developed high toughness insulated castable, which meet the above working conditions.
The high toughness insulated castable has excellent characteristics: bulk density≤ 2.0g/cm^3, compressive strength after burn(1400ºC) 800MPa, wear resistance after burn(1400ºC) ≤ 8cm³, liner change rate after burn(1400ºC) ±0.5%, the using temperature can reach 1400ºC.
