Dedusting System for Blast Furnace 9, Germany

Projekti andmed

Asukoht: Duisburg, Saksamaa

ThyssenKrupp Steel Europe operates a total of four own blast furnaces at its site in Duisburg, Germany. Blast furnace 9 originates from 1962 and was already completely revamped and enlarged in 1987. In 2012, it was again shut down and brought up-to-date with the latest technology. During this refurbishment, the dedusting system of the casthouse received new insulation. Blast furnace 9 started operation again in 2015.

  • High safety standards had to be consistently adhered to during modernization, both regarding the erection of the scaffold as well as its utilization.
  • Almost limitless possibilities to combine all system components of the scaffolds during the insulation work were expected. And all this at a cost-effective price.

  • Optimal work conditions
  • Highest degree of safety thanks to the extremely flexible system scaffolding
  • Flexible adjustment to local conditions without time-consuming tube and fitting system
  • Use of system steel beams from the PERI rental park considerably reduces the amount of material and the time and effort spent on erection or dismantling.

With PERI UP Flex, the most suitable grid dimensions can always be realized and it is 100 % compatible with other PERI system components. And the integrated protection against lifting in the steel decks fully complies with our high safety requirements.

  • Project-specific, adjusted work scaffold based on two compatible modular-type kit systems: PERI UP and VARIOKIT. Both systems are based on standardized, metric grid dimensions.
  • The scaffold with a 5-cm grid in longitudinal, horizontal and vertical direction renders the use of the system scaffold extremely flexible and allows for almost any type of adjustment to the local conditions.
  • Integrated stair towers with 75 cm wide aluminum stair brackets ensure safe and fast access to all floors.
  • Steel decks are immediately secured against lifting off without any effort by the integrated lock against lift off.
  • The ”Gravity Lock“ provides automatic locking when placing the ledger into the rosettes of the standards.
