used as radical temperature
change industrial furnace
|
Every kind of burner
and ceramic kiln furniture |
These products made of natural raw material
have high refractoriness under load, good thermal shock resistance,
excellent wear resistance and slag resistance. They are suitable to
be used in iron and steel industry, chemical industry, glass industry,
ceramic industry and other thermal industrial furnace. |
