About SiC Refractory Plate/Slab

Made of our own SiC raw material, SiC protection tubes can improves temperature aluminum liqiud quickly, good thermal -shock resistance, no crack. It is widely applied in nonferrous metal casting.

Application

Mainly used in nonferrous metal casting.

Features

1. It quickly improves temperature of aluminum liquid, with good conductivity of 16-18 w/m.k. The sheath wall is thin to 15-20mm.

2. It won't be melted or eroded by aluminum liquid, and will not contaminate the liquid.

3. It takes on small heat expansion of 4.2* 10-6, and good thermal-shock resistance. There will be no crack, no dreg adhering or coming off.

4. It works well when immersed in aluminum liquid even the temperature is such high, and can work for long time.

5. It is easy to install when using, and easy to maintain.
