Non Ferrous Silicon Nitride Thermocouple Components Protection Sleeve One End Closed
1) Silicon nitride thermocouple protection tube is formed by CIP , then machined to accurate dimension, and put it into Reaction-Sintered furnace for sintering.
2) Silicon nitride thermocouple protection tube have the characteristics of high and equal density, good dimensional accuracy , etc. Silicon nitride is especially suitable for thermocouple protective cannula measuring temperature of molten aluminum for its anti-fusion.Our company can do any types as customers’ required.
Outstanding corrosion resistance to molten aluminum alloys and flux contamination free.
Oxidation rarely accurs at operating temperature(up to 800 C), which allows hi-cera to maintain stable performance for a long service life.
3.Thermal shock resistance
Superior thermal shock resistance allows hi-cera protection tubes to be inserted in molten aluminum directly with simple preheating.
The highest strength among ceramics allows a thin wall thickness.
Excellent wear resistance gives degassing rotor shafts a long service life at a high speed revolution.
Exceptional acid resistance against acids such as hydrochloric acid and sulfuric acid permits removal of sticking matter on the surface with such acids.
|Property of Silicon nitride products|
|Volume density||g/cm 3||2.77|
|Thermal expansion coefficient||a×10-6||2.51|
|Fracture toughness||(Mpa*m -1 )||2.8|
Used to protect the temperature-measuring components,
make the components isolate from the outside substance,
reduce and prevent the corrosion, oxidation and mechanical damage to the components during measuring.
