Product Description

Corundum Plate made of high technical ceramics belongs to the category of furnace accessories. Due to the characteristics of high hardness, good wear resistance, high strength, high resistance to corrosion and dimensional stability, they are primarily used by universities and research laboratories in high-temperature annealing and melting processes.


Application

High temperature alumina corundum mullite ceramic setter plate for kiln furnace has become a trend. The cordierite mullite hollow and solid plates are used more often in sanitary tunnel kiln, shutle kiln with the connect pieces of pillar and support. Corundum Plate is widely used in many industrial fields such as metallurgy, machinery, chemical industry, electronics, aviation and national defense.


Advantages

1.Corundum Plate has excellent strength at ambient and elevated temperatures.

2.High compressive strength.

3.Very low levels of iron and other impurities.

4.Lightweight and energy-efficient.

5.Lower heat storage than denser refractory.

6.Heats quickly and economically to operating temperature.
