Product Introduction:
The high alumina wear-resistant ramming mass adopts composite binder and optimizes the aggregate gradation, adopts ultra-fine powder technology, so that the lining is more dense and has good wear resistance.Application:
This product is widely used in the settler shell, inner gas collection chamber, main air inlet pipe, standby catalyst inclined pipe, regenerated catalyst inclined pipe, semi-regenerated catalyst inclined pipe, regeneration standpipe in the petrochemical industry catalytic cracking equipment (FCCU). It can also be used for the upper and lower inclined pipes of the external heat extractor, the three-rotation-chimney flue, the oil and gas pipeline, the external circulation pipe of the coking tank, the stripping section, the three-rotation head and cone section, the three-rotation flue gas outlet and other parts. The working temperature is generally 500ºC~600ºC.
