Product Description

99% Pure Silicon Nitride Thermocouple heater protection tube

Product Description

Riser Tubes offer long service lifetimes, due to good thermal shock resistance and good corrosion resistance. This extended service life translates to longer intervals between cleaning and less production downtime for tube removal and replacement.

 

Features and Benefits

 • Gas-tight

• Long life >12 months

• Unaffected by corrosion

• No melt contamination

• Can be used in melts containing sodium and strontium

• Resists build-up of dross

• High temperature resistance up to 1,300°C

• High thermal shock resistance

• No preheating required at operation temperatures below 900°C

• Easy cleaning of bake-on • Best price/performance ratio

Application

Molten aluminum is processed at temperatures between 680°C and 800°C. Radiant heater tubes are used to keep melts on temperature. The tube material should have sufficient mechanical stability to withstand the stresses of operation. In addition, the material must be resistant to chemical attack by the melt, and must not contaminate the melt with loose particles.
