International technology Group Andritz has been awarded an order to supply a new walking beam furnace for the Donawitz plant of voestalpine Schiene GmbH, Austria, Europe’s leading supplier of railroad tracks. Start-up is scheduled for the beginning of 2016.
Andritz Maerz will supply the turnkey furnace plant with an output of 185 t/h, including steel structure, refractory lining, transport system, combustion system, instrumentation and control system, mathematical furnace model to optimize the various thermal furnace processes, buffer bed with separating systems, feed conveyor with automatic billet identification, and a complete hot water cooling plant with recooling and emergency cooling systems.
In order to make best possible use of the residual heat from the waste gases, a heat recovery plant is planned to supply the district heating system. Thanks to Andritz heating technology, heat consumption can be reduced to a minimum in spite of the very uniform temperature maintained, and maximum reductions can be achieved in emissions of NOx and CO.
