Construction method

Refer to our factory's construction procedures

Application

1-4Related parts such as preheaters and corresponding pipes

5Related parts such as preheaters, decomposition furnaces, riser ducts, secondary air pipes, and chain sections

High-temperature parts such as front and rear kiln inlets, kiln hoods, and cooler front ends of cement kilns

Front kiln inlets of large cement kilns, tertiary air pipes, burners, etc.

High-temperature parts such as front and rear kiln inlets and coolers of cement kilns, and linings of other industrial furnaces

High-temperature wear-resistant parts such as front and rear kiln inlets and coal injection pipes of large cement kilns, and linings of other industrial furnaces

Same as aboveYJ-75, but strength and thermal stability are better thanYJ-75

characteristics

High early strength, short demolding and curing time, greatly shortened construction period.
