Double-row filters for a steelworks in Russia

One of our special projects is the de-dusting of a 370-tonne RH-duplex and a Twin-LF plant from SMS Mevac produced for MMK.

Both the size of the de-dusting unit and the assembly in Magnitogorsk in Russia has presented the Münstermann team with a number of challenges.

Design of the unit

The bag filters are of the Type SK60/6.0m XII DR for continuous operation. The type designations in detail are:

  • SK60/6.0m: bag chamber filter unit with 60 bags is 6 metres in length
  • XII: This unit has 12 chambers
  • DR: This unit is in the double-row design

The cleaning of the filters can take place in the SEMI-operating mode or offline. The unit has a continuously variable volume airflow control system of the individual filter chambers and cleverly devised flat slider system.

Further technical details

The volume of air to be cleaned in the de-dusting unit is 390,000 m3 /hour (at 60°C) and can be operated up to maximal 130°C. The residual dust content after filtering is less than 10 mg. The dust concerned is metal oxide and miscellaneous aggregates.

Additional scope of delivery

  • Engineering of the chimney stack, silencer and the raw and clean air pipelines
  • Dischargers, shut-off and butterfly valves
  • Electric fan with a sound-proof housing with a motor rating of 1,250 kW
  • SPS-filter control system

From the placing of the order to commissioning in Magnitogorsk a period of just less than 9 months was needed, which represents a remarkable achievement for a plant of this size and at a location in the eastern regions of Russia.
