Silicon nitride Riser tube & Stalk

产品特点

Practical application proves that silicon nitride ceramic SG-28 is very suitable for the riser tube & stalk of low-pressure casting;
Compared with commonly used cast iron, aluminum titanate, silicon carbide and other materials, silicon nitride ceramic has the best thermal shock resistance and a service life of more than one year;
Due to the low wettability to aluminum liquid,it reduces the slagging of the inner and outer walls of the riser tube & stalk, which is convenient for daily maintenance;
Silicon nitride ceramic S-28 has excellent corrosion resistance, which can reduce the pollution of aluminum liquid, therefore, it will be beneficial to improve the quality of casting for customers.
