ANDRITZ received an order from steelmaker ArcelorMittal for the supply of two top- and bottom-fired walking-beam furnaces for its 80-inch hot-strip mill in Burns Harbor, Ind. Start-up of the furnaces, which will replace the existing pusher furnaces, is scheduled for 2020. Each furnace will heat carbon-steel slabs at a rate of 500 tons per hour. The combustion systems include low-NOx burners that will reduce emissions. The scope of supply includes the design, supply, erection supervision and commissioning of the furnaces as well as comprehensive training of the operating and maintenance personnel.
The furnaces will reduce overall fuel consumption as a result of their long, unfired preheat zones, individual burner control and improved insulation (including efficient ANDRITZ skid insulation).
