Mullite Refractory Castables & Ramming Masses
If you are weary of Alkalies in your feed combining with moisture to prematurely destroy your refractory-castable integrity; producing low melting glassy products that initiate accretion & process build-up;
If you are replacing your lining material every 2 years; due to degradation of the refractory & its anchoring systems from exposure to combustion products or chemical, Slag, CO Spalling attack or , cracking due to thermal shock;
If you are keen on reducing heat leakages from your shell

TRY our High Temperature, Abrasion, Chemical attack & Thermal Shock resistant Proprietary Mullite formulation.
Available as spray-able ramming mass as well as monolithic forms for critical applications such as furnace lining blocks, burner nozzles or kiln furniture, fabricated as per your drawing.

Sourced from:
Bajaj Associates, India; manufacturer of Sintered Mullite based refractory castables;

TESTIMONIALS.

HOSPET STEELS LTD. :

Dear Mr. Bajaj,

Having used your material from 2006, we have documented the following advantages.:

The Ladle skin temperature, after casting has now decreased by 80C compared to our previous lining.

The EOF shell skin temperature is now cooler by 60C.

The surface finish & integrity quality is better & does not crumble during re-bricking. This is for the 3rd year running.
We got a 5 year campaign life of Down Commer linning vis-a-vis the standard 2 years from our normal castable in the EOF O P SINGH,G M ( SMS & PPC), HOSPET STEELS LTD.
