The advantages are

1.Si3N4 material has better thermal shock resistance and high-temperature mechanical strength, light weight, high strength and easy to operate. It will not burst even if exchange is done in the course of processing, making it easy for production and maintenance.

2.Si3N4 material has the low conductive advantage. Its low specific heat minimizes loss of heat. This will be conducive to achieving the accuracy of temperature measurement for the thermocouple protection tube.

3.Molten aluminum’s low wettability prevents stick of slagging in the tube, thus easy to maintain and operate.

4.Si3N4 has excellent corrosion resistance and wear resistance, and ensure longer working life. If proper maintenance, the actual using life can be up to 2-3 years. 

Quality control

1. Checking raw material before producing.

2. Checking one by one before the assebling

3. Checking one by one during the production

4. Have the random inspection before the delivery.
