First DANCU gearbox shipped to Zaporizhstal

New blast furnace top-charging technology will set new standards in reliability and availability

After completing a 20-day workshop test, including six full days running continuously to simulate the operational situation at the client's site, the first DANCU gearbox has been shipped to Zaporizhstal in Ukraine.

The DANCU technology is a co-development by Danieli Corus and Danieli Centro Metallics. It was developed with the objectives of achieving unparalleled availability and easiest maintainability. All main components are designed and manufactured to be failure–free or redundant for fully uninterrupted operations.

Some highlights are:

  •  Fully hydraulic operation to eliminate the vulnerabilities of existing electro-mechanical designs
  •  Full redundancy of tilting and rotation equipment
  •  Bigger main bearing to prevent torque inversion
  •  Closed-circuit cooling

In addition, given the client's operating environment, the design for this project was modified for blast furnace operation on hot sinter. To accommodate this practice in this cold environment, all major equipment is engineered and manufactured for the ability to accept raw materials with temperatures up to 700 degrees as well as, e.g., frozen coke.

The DANCU gearbox will be installed during the current blast furnace modernization. A second, spare unit also will be shipped to the client under the same contract.
