Si3N4 Silicon Nitride Riser Stalk introduction
Sialon,silicon nitride,alumina and silicon carbide are known as engineering ceramics. Among them, silicon nitride has the highest thermal shock resistance. Thus, it makes handling and preheating control easier.Silicon nitride riser tube/stalk has been in use instead of cast iron and old ceramics in molten aluminum.
Si3N4 Silicon Nitride Riser Tube Stalk Features:
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.
