ThyssenKrupp MillServices & Systems to build a new coke quencher for HKM

Tuesday, Jun 29, 2010

ThyssenKrupp MillServices & Systems GmbH, Oberhausen, Germany, has been awarded a contract by Hüttenwerke Krupp Mannesmann (HKM), Duisburg, to build and supply a new coke quencher to replace the one presently in use.

The contract covers the complete engineering revamp, a newly engineered undercarriage, platforms, hydraulics and electric cab including equipment.

The existing structures will be taken into account when designing the new equipment. Other elements of the quencher include the drive system, the subframe, coke receptacle with water cooling unit and internal/external flaps. Included in the scope of the contract are transport, assembly, and on-site acceptance.

At the Duisburg-Huckingen steel mill the coke quencher transports the glowing coke from the oven to the quenching tower and from there to the coke ramp. The fully automated unit must withstand temperatures of over 1,000 °C and be able to maneuver with up to 5 mm precision. With unit loads of around 40 t, the machine is capable of 180 quenching cycles in 24 hours.

Once the individual parts of the total plant weighing around 240 t have been delivered by ship and heavy-haulage vehicles, the coke quencher will then be assembled at the mill. Commissioning is scheduled for May 2011.
