Silicon Nitride Heater Protection Tube
Superior thermal shockresistance.
High strength and easy to handle.
This ensures long life.
Protection tubes for electric heaters and gas burners are already practically in use.
● Silicon nitride ceramics is superb in heat resistance. So, the product withstands severe thermal load of high temperature heaters.
● It has excellent thermal shock resistance. So, insertion and withdrawal during batch operation will not affect the performance.
● Superior corrosion resistance does not allow eluted contamination into molten metal. The purity of molten alloys is maintained.
● Low wettability against molten aluminum provides easy mainte-nance and handling.
● Actual performance shows more than 1 year operating life.
