Silicon nitride Riser Tube For Low Pressure Casting, The features of Solicon Nitride Riser Tube are the same with aluminum titanate ,but the density and strengh of Silicon Nitride are higher than aluminum titanate,so the service life is 5-20 times longer than other ceramic riser tube that the replacement is greatly reduced,Widely applied in aluminum alloys casting, non-ferrous metal metallurgy,etc.
