Silicon Nitride Ceramic Tube For Riser introduction

Si3N4 Stopper pipe is resistant to aluminum solution and fusion. We use silicon nitride materials to manufacture stopper pipes, heating unit production tubes, ventilation rotor shafts, liquid inlet(lift) riser tubes and other protection tubes for aluminum alloy casting.

since advanced modern technology such as cold isostatic pressing and high remperature reaction sintering have been used ,the products have been well recognized by general customers for their high density.

Si3N4 Sealing Tube 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 resistance 
Exceptional acid resistance against acids such as hydrochloric acid and sulfuric acid permits removal of sticking matter on the surface with such acids.
