ArcelorMittal is again counting on the strengths of the AUMUND Drag Chain Conveyor Type LOUISE

The steel maker ArcelorMittal is building on proven solutions and reliable partners in Brazil. About 20 years ago, a shock-pressure-proof drag chain conveyor was ordered for Brazil from LOUISE Fördertechnik before this company was acquired by AUMUND Fördertechnik GmbH, and now AUMUND has won an order for another drag chain conveyor type LOUISE TKF. The shock-pressure-proof design of its predecessor was no longer required for the new model because of the change in classification of the plant segment. The dispatch of the machine is planned for June 2017.

The earlier model drag chain conveyor was ordered in 1998 by the then Brazilian arm of the Luxemburg steel company Arbed, CSBM, Companhia Siderurgica Belgo Mineira. Arcelor was created by the merger of Aceralia and Usinor and merged with Mittal in 2006 to become ArcelorMittal, the world’s leading steel concern.

Around fifteen years ago, AUMUND Fördertechnik GmbH integrated the products of the LOUISE subsidiary into its own portfolio. This double strand drag chain conveyor with a capacity of 3 kW, a centre distance of 10.4 m and a performance of 25 t/h, will be used for bunker extraction.

The previous machine proved its durability in an interesting way. One of the supports of a weighing cell collapsed and caused one side of the silo to subside. A large portion of the fallen steelwork weighing several tonnes was resting on the discharge conveyor. If it had not been for the strength of this machine, the silo may well have collapsed completely, and the damage would have been far more extensive. “It is of course not the usual method by which we test the quality of our machines!” remarks Ingo Dietzold, Managing Director of AUMUND do Brasil in São Paulo.

ArcelorMittal Brazil boasts 11,000 employees spread over 27 manufacturing and administration sites, and has a production capacity of 11.3 million tonnes of steel and 7.1 million tonnes of iron ore.
