The characteristics of silicon nitride tube

Silicon nitride is currently the most effective and widely used material for temperature measurement and temperature control of non-ferrous metal castings in the world. The silicon nitride tube has the following characteristics:

1. Excellent thermal conductivity, thin tube wall (only a few millimeters), very fast response to temperature, and the temperature of molten metal can be measured within 1 minute;

2. It will not melt at high temperature and will not pollute the molten metal;

3. Excellent thermal shock resistance, oxidation resistance, thermal shock resistance;

4. Strong corrosion resistance, corrosion resistance and erosion resistance;

5. Not easy to accumulate slag, easy to maintain;

6. The product is an electrical insulator;

7. Can be used in alloy melts containing sodium and strontium;

8. The service life is more than 12 months, the longest can be used for several years, and the cost performance is very high.
