The primary use of Refractory Castable:

1.Material for metallurgy, petroleum, chemical and other industries kilns.

2.Part of refining installation, like ladle cover.

3.Insert for roof of the kiln.

The main features of Refractory Castable:

1. 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 low 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.




Here is our process flow:



Our conventional packaging :


1. We sealed the products with two layers of leak proof and waterproof plastic woven bags, and then, we choose appropriate wooden trays to support them, after that, use a strong packing belt to fix the whole package and wrap multi- layer protective plastic round.


2. We can also package according to your other requirements.
