Refractory Shapes Product Range

United Industries offers a comprehensive basket of refractory bricks suited for various industrial applications:

Fireclay Bricks (Al₂O₃ 30–45%; max service 1350–1500°C): Grades FC30, FC35, FC40/42 (equivalent to SK32–SK34). Ideal for cost-effective, thermal shock-resistant solutions.

High Alumina Bricks (Al₂O₃ 45–99%; max service 1500–1800°C+): Grades HA50 (45–55%), HA60 (55–65%), HA70 (65–75%), HA80 (75–85%), HA90/95+ (85–99%). Premium options for high refractoriness and slag resistance.Higher Al₂O₃ content enhances density, strength, and erosion resistance but may reduce thermal shock tolerance unless optimized.

Precast PreFired Shapes (MOC Low Cement Castable) UNITED Make PCPF Shapes are highly recommended for special shapes where abrasion and high temperature comes in. SPecially in Furnace Hearth Area, Roller Blocks Area etc.
