The service life of silicon nitride riser tube is more than 10 times that of traditional riser tube, which greatly reduces the number of replacement of riser tube, fully guarantees the continuous and automatic production, and is widely used in aluminum smelting industry and non-ferrous smelting industry.
Process: isostatic pressing + high temperature sintering
Features: 1) High strength and good compactness
2) Low coefficient of thermal expansion and good thermal conductivity
3) Excellent thermal shock resistance
4) Non-ferrous metal melts such as aluminum melt are not wetted
5) Good corrosion resistance
