Products Range:
Zibo HITECH MATERIAL CO., LTD is a specialized manufacturer and supplier of refractory, we have two factories, one is for refractory brick and the other is for refractory castable, precast and shapes ceramic fiber etc.
Typical Applications:
Material for metallurgy, petroleum, chemical and other industrial kilns
Part of refining installation, like ladle cover ,Insert for roof of the kiln
The advantage of these products:
1.The dosage of cement is low, the content of calcium only accounts for 1/4-1/3 of common refractory castable.
2. Water consumption rate during the construction is almost 1/2 or 1/3 of the common refractory castable, so
the low cement refractory castable has high density and lower porosity.
3. High normal temperature cure property, intensity will be increased after medium temperature and
high temperature.Three or five times more than common refractory castable.
4. Good volume stability under high temperature.
