SG-28 Silicon Nitride Ceramic Thermocouple Protection Tube
The SG-28 silicon nitride ceramic thermocouple protection tube is made of silicon nitride, compared with other materials such as cast iron, graphite, and carbon nitride, it can not be corroded by molten aluminum.
Advantages And Features
1. Long service life and low maintenance cost
Due to the advantages of silicon nitride ceramics, such as high-temperature strength, strong heat shock resistance, and good corrosion resistance, the service life is generally more than one year, thereby reducing the replacement and maintenance cost.
2. Easier installation and maintenance
Silicon nitride ceramics can maintain flexural strength above 500MPa and good heat shock performance below 800 ° C, so the wall thickness of the product can be thinner, coupled with its low infiltration with molten metal, so there is no need to brush the surface coating, but also make the installation and maintenance of porcelain parts easier.
3. No pollution to liquid aluminum
The infiltration of silicon nitride to molten metal is low, and it will hardly react with liquid aluminum, so it will not cause secondary pollution to liquid aluminum, which is of great help to stabilize the quality of casting products.
