The features of silicon nitride riser tube are the same with aluminum titanate, but the density and strength 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.

  Shape: tubular

Parameter：inner diameter，outer diameter，wall thickness，length，service life

Application：aluminum alloys casting，non-ferrous metal metallurgy，etc
