The long-term practical use proves that SG-28 Silicon Nitride Ceramic is very suitable for low-pressure casting machines and dosing furnaces.
Compared with traditional cast iron, silicon carbide, carbon nitrogen materials and Aluminum Titanate, Silicon Nitride Ceramics have the best high-temperature strength and the service life can last for more than one year.
The low wettability to aluminum liquid, makes the SG-28 Silicon Nitride Ceramic effectively reduce the slagging on the inner and outer walls of the riser tube, reduce the shutdown loss and maintenance.
SG-28 Silicon Nitride Ceramic has excellent corrosion resistance, which can effectively reduce the pollution to the aluminum liquid, and improves casting quality.
