thermocouple protection tube

الوصف

Pressure sintered silicon nitride material thermocouple protection tube for protection measure liquid aluminum, titanium liquid temperature thermocouples used. Features: 1, without the occurrence of erosion and molten aluminum, the surface is not bonded aluminum liquid, more conducive to the improvement of the quality of aluminum products; 2, strong antioxidant, *0 degrees Celsius below the long-term use in the air, oxidation does not occur; 3 **0% dense, aluminum can not be immersed in liquid, reaction sintering process to produce silicon nitride life is very short, there is a lot of material pores, long aluminum liquid will penetrate; 4, thermal shock resistance and strong; 5, aluminum in the life of at least 6 months, the actual test more than one year.
