Product Description

Corundum castable

Product Description:

CorundumRefractory castableIt has the characteristics of high abrasion resistance, good fluidity, etc., which is convenient for construction.It is mainly used for parts that are easy to scour and wear, such as the combustion chamber, separator and flue of circulating fluidized bed boiler.

Product Features:

(1) It can flow under its own weight without vibration;

(2) It can be spread and unfolded automatically and can reach the parts that cannot be reached by the vibrating castable;

(3) It can better ensure that the performance of the castable is fully reflected in actual use:

(4) It can be pumped for construction, reducing labor intensity and speeding up the construction cycle;

(5) Reduce noise pollution;

(6) It is easy to carry out construction performance test on site.

Product Usage:

Mainly used in the furnace belt of circulating fluidized bed, hanging screen, (water-wall type) cyclone separator and other thin-walled furnace walls, high wear resistance, erosion resistance and The ramming layer of the tortoise shell net, plusIndustrial equipment such as the lining of the first-stage and second-stage reformer of synthetic ammonia.
