To remove H2 gas from molten aluminum, a silicon nitride/si3n4 pipe is used to feed the N2 or Ar gas. As silicon nitride rotor is used to stir and disperse the gas throughout the molten bath.
Charcteristics of silicon nitride riser tube
Young's Modulus of Elasticity
Coefficient of Linear Thermal Expansion
Heart Shock Resistance
Maximum Available Tempereture
Main Features of Heat Resistant Silicon Nitride Ceramic Shaft And Rotor
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.
