Advantage of Silicon Nitride Heater Protection Tube

1)Si3N4 heater protection tube with castable refractory;

2)With good thermal shock resistance and high temperature mechanical strength, therefore, the products can withstand severe thermal load of high temperature heaters;

3)Repeated insertion and withdrawal of the products in the course of operation will not affect the performance.

 

Applications  

Silicon nitride protective tube is widely usedfor non ferrous metal casting.Especially for measuring the temperature of liquid aluminum. 

Features 

1.Don’t react with molten Al,the surface is not bonded with Al,improve the quality of Al products;  

2.Good resistance to oxidation,can work for a long time below 1000°C in atmosphere,no oxidation;  

3.100%compactness,molten Al can not pollute it,but the Si3N4 tubes by reaction sintering have a very short life,there are many pores,will be polluted from molten Al after long

time working;  

4.Good thermal shock resistance; 

5.the working life is more than 6 months in Al industry,and more than one year after testing.
