Riser tube




Practical use has proved that SG-28 silicon nitride ceramic is very suitable for the riser pipe of low-pressure casting.

Compared with commonly used cast iron, aluminum titanate, silicon carbide and other materials, silicon nitride ceramics have the best thermal shock resistance, with a service life of more than one year.

Low wettability to aluminum water reduces slagging on the inner and outer walls of the riser pipe, which is convenient for daily maintenance.

Good corrosion resistance, can reduce aluminum water pollution, and help improve the quality of castings.
