Low thermal conductivity alumina oxide insulation brick for hot blast stove
Characteristic:
• Excellent corrosion resistance to neutral slag and liquid mental pentration at high temperature.
• Withstand verious attacks from volatile matters, such as ash from coal, lignite, fuel oil, etc.
• High bulk density, high mechanical strength and good resistance to thermal spalling,good volume stability at high temperature.
Application:
Alumina oxide brick is widely used in the insulating layers and linings of various heat engineering equipments such as hot blast stove, heating furnace, boiler, tunnel kiln and so on.
