Practical use has proved that SG-28 silicon nitride ceramics are very suitable for low pressure casting risers.

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

The low wettability to aluminum water reduces the slag formation on the inner and outer walls of the riser, which is convenient for daily maintenance.

It has good corrosion resistance, can reduce aluminum water pollution, and is conducive to improving the quality of castings.
