Silicon Nitride Dosing Tube
Type of Material:
Silicon Nitride is a chemical compound of silicon and nitrogen. It is a hard ceramic and is mostly used in high-endurance and high-temperature applications.
Advantages:
1. High strength, toughness
2. High thermal shock resistance
3. Resistance to corrosion
4. Constant temperature monitoring of the melt
5. Non-wetting to most non-ferrous alloys, making it resistant to build up of dross
6. Minimal dross buildup
7. Withstanding of a certain degree of mechanical shock
8. High thermal conductivity
9. Extended working life
10. Stronger than other dosing tubes
Application:
Our dosing tubes are used for dosing furnaces. These dosing tubes offer greater service life, which means less down time for manufacturing.
Manufacture technology:
Shaping: Cold ISO-static pressing (CIP)
Sintering: Reaction bonded sintering (RBSN)
Machining: Precision machining to minimum tolerance
Technical Parameter of RB Silicon nitride products as the following chart:
We can also manufacture dosing tubes made of other materials and sizes to suit.
Pls. Let us know your detail technical and cost requirement, we will provide the most suitable solution and the best products for you.
