Castables

Refratab

High Purity Tabular Alumina Castables

The best choice for Burner Blocks, Refractory Quarls, and Burner Throat Tiles must have a low iron-oxide to withstand spalling due to Carbon Monoxide attack. These shapes are also subjected to sharp thermal gradients; therefore they need to have excellent thermal spalling resistance. Hence shapes made out of Sillimanite are ideally suited for the above application areas.

Also our, Sillimanite Element Holding Bricks offer low iron contamination in industry application.

Refracast

High Purity Dense Castables

High Purity Dense Castables are refractory castables suitable for high temperature applications. These castables are available in various grades suitable for a specific range of operational conditions.

These refractory castables are hydraulic setting and can be casted or moulded to any shape and can also modified for gunning of furnace linings.

Specification

Refracrete

Medium Purity Dense Castables

Refracrete medium purity dense castables are suitable for use in applications. This group of castables contains medium purity high alumina cement as the refractory binder and castables are used for oxidising atmospheres.

These refractory castables are hydraulic setting and can be casted or moulded to any shape and can also be modified for gunning of furnace linings.

Specification

Refracast GB

With the advancement in properties of castables by new techniques and innovations, superior grade castables which can be easily installed against shuttering, faster setting and strength development without the elaborate curing and heat dry out operations has facilitated industry applications in a significant way especially achieving a quicker turnaround.

With the use of special additives fine aluminas, fume silica etc. superior bond in the matrix is achieved.

It is essentially a monolithic mix, which does not require any vibration during installation that is it will have free flow without any segregation. Gel Bonded Castables have excellent properties making it superior to conventional castables.

Specification

Insulating Castables

Refralite

Refralite are a range of insulating castables to conserve heat in furnaces. They are light but strong and have low conductivity, serve as either hot face or back up insulating refractory lining.

These castables are produced in density range of 400 to 1600 kg/m3. They are available mainly in two different grades – medium purity and high purity. The high purity (Low Iron) variety is suitable for reducing environments.

Low Cement Castables

Reframon

Low Cement Castables

Reframon LC is a low cement Castable having high strength at all temperature levels. These Castables are used in locations needing high abrasion resistance.

Ultra Low Cement Castables

Reframon ULCC are ultra-low cement castables which contain even lower level of cement than low cement castables.

Above LC/ULCC Castables offers following advantages:
  • Low CaO content ensures high refractoriness.
  • Excellent hot strength and MOR at all temperatures.
  • Lower apparent porosity after firing offers better corrosion resistance.
  • High abrasion and spalling resistance.
  • High volume stability.
Specification

Mortars

Dense / Insulating Mortars

These mortars are used as jointing material for High Alumina Bricks and Insulation Bricks.

Some of the mortars are supplied as two-component system, where liquid binder is separately provided with powder material. In such a case, liquid component should be used only as per our recommendation. Where water is used as a liquid component, the amount of water used should be such that it results in trowelling consistency.
