SG-28 silicon nitride ceramics are widely used as thermocouple protection tubes and have a service life of more than one year due to their excellent high temperature performance.

Compared with cast iron, graphite and other materials, silicon nitride will not be corroded by aluminum liquid, thus ensuring the accuracy and sensitivity of the measured temperature;

Silicon nitride ceramics have low wettability to molten aluminum, so there is basically no need for on-site maintenance.
