SILICON NITRIDE (SI3N4) THERMOCOUPLE PROTECTION TUBE FOR ALUMINUM INDUSTRY

Silicon Nitride (Si3N4) Thermocouple Protection Tube

High-performance silicon nitride ceramic materials developed for the aluminum industry has significantly improved thermal and mechanical properties than similar products. On this basis, the "L-shaped high thermal conductivity submerged heating "Appliance" will bring revolutionary progress to aluminum industrial equipment.

Silicon nitride ceramic is widely used as a thermocouple protection tube. Due to its excellent high-temperature performance, the service life is more than one year.

Advantage:

Silicon nitride ceramics have low wettability to molten aluminum, so on-site maintenance is basically unnecessary.
Compared with cast iron, graphite and other materials, silicon nitride will not be corroded by molten aluminum, thus ensuring the accuracy and sensitivity of the measured temperature;
