Application:
Refractory Mortar High Alumina Power Shape Refractory Material used in thermal insulation layer(preheater,decomposing furnace,tertiary duct,kiln hood,coller,etc)
The Feature:
1. Slag resistance
The slag resistance of high alumina refractory mud is one of the important indicators of its fire resistance. The stronger the slag resistance, the longer its service life.
2. Heat resistance
The heat resistance of high aluminum refractory mud is its ability to maintain stability in high temperature environment, which is one of the most basic performance indicators.
3. Compressive strength
The compressive strength of high alumina refractory mud is its ability to withstand external force at high temperature, and is one of the important indicators of its durability.
