Heater Protection Tube
Si3N4 material is applied to molten aluminum liquidheater protection tube and the gas burner protectiontube , used in Aluminum, Tin, Lead, Zinc ect.
kinds ofMetallurgical industry . the advantages are:
- Si3N4 material has the better thermal shockresistance and high-temp mechanical strength,sothe product can withsand severe thermal load of hightemperature heaters.Even insertion and withdrawalduring batch operation will not affect the performance.
- Because of the excellent corrosion resistance,sothere is no eluted contamination into molten aluminumthereby keep the molten metal purity.
- Low wettability against molten aluminum provideseasy maintenance and handling.
- Si3N4 material has well high-temp mechanicastrength, actual performance showsmore than 1 yearoperating life.
