If cracks or damage appear on refractory block(s) of a walking beam furnace for slab reheating the traditional repair method repair consists of removing the damaged block and replacing it by a new one. This method requires cooling down of the furnace and therefore to stop the production. An alternative to repair is spraying a wet refractory mix on the hot surface with a projection method. However gunning on a hot surface depends of a lot of supra tk society for kids parameters and successful repair operation remains uncertain because of thermal shocks due to water.

FIB-Services markets a ceramic welding technology witch allows the repair at service temperature. As a consequence, it leads to energy saving and to maintain the production constancy.


  1. Repair at service temperature
  2. Dry repair material
  3. No cool down / reheating requested : energy saving
  4. Production constancy
  5. Quick repair : less than 8 hours production stop
  6. Strong adhesion onto surface under repair
