High alumina refractory castable 1 good abrasion resistance 2 be used in reactor,regenerator and cyclone separating device

Application:

High alumina refractory castable is applicable to regenerator,lifting pipe chute,etc.and the insulating &werable lining for flue pipe with the temperature less than 800 centidegree in catalytic cracking unit.The lining material for the heat insulating layer and abrasion resistant layer can be construced by manual daubing or mechanical spraying or painting.
