These bricks are manufactured by the sawdust process using selected grades of china clay and kyanite for hot face as well as back up applications. Particularly notable is the HFK brick, which is one of the most economical insulations in its classification temperature. Rajhans also manufactures high CCS insulation tiles, RHR HSI for glass melter bottom and can supply the same in any size.

This range of bricks has been entirely developed through indigenous research and is formed by the vibro-casting method. Vibro-casting ensures extremely low thermal conductivity and proportionately high strength. These bricks are engineered for cold face as well as hot face applications and can withstand temperatures of upto 1500°C. Tailor made solutions for kilns and furnaces based on vibro-cast bricks can be forwarded with cost benefit analysis in terms of energy savings.
High Alumina insulations
This range of insulation bricks have alumina content extending upto 95% alumina and are mostly use for applications starting from 1500°C.These products are distinguished by their pure chemistry, high hot strength and excellent volume stability in service. Especially notable are bubble alumina based bricks.
