Refratechnik Hybrid castables: Also suited for low temperatures.

The new development: Hybrid technology

Hybrid technology permits the combination of faster heat-up and high strength at low temperatures. It is therefore­ ­ideally suited for applications in which high strengths are required in the range of 20…1000 °C; for example in the production of ­prefabricated components or the lining of fluidized bed furnaces and refuse incineration plants.

Advantageous

Strength comparisons of REFRACAST® Hybrid F-60 AR/R and a Sol-Gel bonded castable.

Clearly advantageous

Cold crushing strength of hybrid castables and Sol-Gel bonded castables at 20 °C/24 h; Hybrid castables exhibit a significant increase in cold crushing strength.

Hybrid castables make all the difference

compared with conventional cement containing castables:

• Faster heating up with shorter downtimes
• Cost and energy-saving
• Very good adherence to existing refractory materials
• Installation possible on hot surfaces and with high ambient temperatures
• Higher application temperature limits
• Optimized thermomechanical behaviour
• Long storage life of 12 months
• Increased cold crushing strength and modulus of rupture as well as optimized abrasion resistance in the temperature range below 1000 °C.
