Non Ferrous Silicon Nitride Thermocouple Components Protection Sleeve One End Closed
Description:
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.
Main Features:
1.Corrosion resistance
Outstanding corrosion resistance to molten aluminum alloys and flux
contamination free.
2.Oxidation resistance
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.
4.Mechanical strength
The highest strength among ceramics allows a thin wall thickness.
5.Wear resistance
Excellent wear resistance gives degassing rotor shafts a long
service life at a high speed revolution.
6.Acid ressitance
Exceptional acid resistance against acids such as hydrochloric acid
and sulfuric acid permits removal of sticking matter on the surface
with such acids.
