Light Weight Insulating Mullite Castable For The Lining Of Rotary Kiln And Industrial Kiln
Another product that we supply is the castable refractories that are low density. These insulating castables pose very low thermal conductivity and are utilized for either high temperature face work or when used for a backup lining, which is found behind dense castables or brick work. Here, the insulating castables are able to decrease the lining’s overall density or the cold face temperature. Their strength, which ranges from low to medium, is based on the fact that their density is low and is the main reason that they are not resistant to abrasion. They are most suitable where they do not have to stand up to much wear and tear.
The main application for Castable are listed below :
•Casting an alternative to fireclay and high alumina brick for application such as glass furnaces , EAF , reheating-furnace, tapping spout , aluminium and jewelry kiln
•Application for cyclone preheated of cement kiln, ceramic kiln , ash coal hoppers coal and incinerators
•Casting an alternative to high a alumina brick at EAF roof core , burner block , nose ring and kiln load
Features and Advantages of refractory castable:
1. High refractoriness, High refractoriness under load.
2. High density, low porosity.
3. Good slag resistance and corrosion resistance.
4. High strength and wear resistance.
5. Good resistance to flake performance.
6. Good thermal shock stability.
7. Scouring resistance
8. Good hot strength.
