HYBRID: Optimized Sol-Gel Technology.

Hybrid technology permits the combination of faster heating 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.
Advantages of hybrid castables compared with conventional cement containing castables:
  • Faster heating up with shorter downtimes

  • Cost and energy-saving

  • Very good adherence on 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.

REFRAJET® Addmix: An innovative injection system

The REFRAJET® Addmix technology is an innovative injection system that was developed specifically for the installation of cement-free sol-gel bonded refractory concretes of the REFRAJET® Nanobond type.

The injection system creates a reactive aerosol that is injected centrally into the continuous flow of dry gunning mix material. A liquid binder can be added to the pre-wetted dry material via a conventional nozzle system at the end of the deliver hose.

Pre-wetting of the dry gunning mix offers several advantages, such as reduced dust generation at the gunning nozzle, less material rebound – particularly during overhead work – plus enhanced bonding to refractory surfaces.
Moreover, the concrete's cold crushing strength and cold modulus of rupture are increased, porosity is reduced, and a denser concrete structure is obtained.
The process has been optimized for cement-free shotcretes of the REFRAJET® Nanobond type, but it can also be used for many other concretes from Refratechnik's product range.
