high quality silicon nitride ceramic roller for molten aluminum

The material is an electrical insulator and is not wet by nonferrous alloys. Silicon nitride is a rather expensive material, but it’s performance to cost benefit ratio is excellent in the applications where it can outperform the normally utilized materials with long life and very reliable low maintenance operation.

 

Performance

1.High temperature resistance,corrosion resistance,and non-immersion with molten metal

2.The thermal shock resistance and not falling, not burst

3.Extremely low coefficient of thermal expansion

4.Anti-oxidation,long service time

5.Could made according to customers’ specification
