Castables

These are dry mix hydraulic compositions of graded refractory aggregates with a suitable bonding material, Fillers & (/or) special Additives. On addition of the prescribed quantity of water to these compositions, a wet concrete-like mass is produced which forms useful castables. Ceramic bond is developed when the same is fired at a certain high temperature.

Available Grades of Refractory Castables :

• Medium purity castables
• High Purity Dense Castables
• Low Cement Castables
• Insulating Castables

High Purity Dense Castables :

• Ideal for High Temperature applications
• Available in various grades with low iron content
• Used for a specific range of operational conditions
• Hydraulically set with easily mouldable and castable shapes
• Specifically designed for diverse combustion conditions
• Applicable for both back-up and furnace exposure

Medium Purity Castables :

• Ideal for Medium Temperature applications
• Used in oxidizing atmosphere
• Hydraulically set, with easily moldable shape
• Used in : Boiler work, general furnace, burner blocks etc.

Low Cement Castables :

• Low cement concentration

• Excellent physical properties
  
  • Low porosity
  • High strength
  • Good abrasion resistance

• Ideal for
  
  • Refractory abuses due to abrasion
  • High temperature applications

Insulating Castables :

• Low densities  are light
• Adequately strong and of low conductivity
• Serving as hot face or backup insulating refractory lining used in reduced conditions.
• Low to medium strength
• Tailored varieties are also supplied to customer’s requirements.
• Substitutes for varieties of imported castables.
