13.8 meters blast furnace for Tata Steel, Orissa, India
Oct 31, 2007
Tata Steel Ltd (Tata Steel), the world´s sixth largest steel producer in terms of actual crude steel production, with geographic footprints in India, South East Asia and Europe, placed a blast furnace order with Metals Technologies (MT), a division of the Siemens Group Industrial Solutions and Services (I&S), for the supply of engineering and key equipment for a new blast furnace. This facility will be part of a greenfield integrated iron and steel works which will be built at Kalinganagar in the state of Orissa in eastern India. The state-of-the-art furnace will feature a hearth diameter of 13.8 meters and will be capable of producing 3.2 million metric tons of hot metal per annum.
In order to further expand their steel production capacity to meet increased global steel demands, Tata Steel will implement three new greenfield steelmaking plants in eastern India. This includes the construction of a six-million t/a iron and steel complex at Kalinganagar in Orissa, which will be executed in two project modules of three million t/a each.
For the first phase of development of the Kalinganagar project Siemens Metals Technologies will engineer and supply key technological equipment for the Blast Furnace No. 1. The furnace will be designed with a hearth diameter of 13.8 meters, an inner volume of 4,300 m³, a furnace top pressure of 2.5 bar, a nominal daily production capacity of 9,150 metric tons and a nominal annual capacity of 3.2 million metric tons.
The blast furnace will be characterized by a low fuel-consumption rate (500-535 kg/metric ton of hot metal, depending on the pulverized coal injection (PCI) rate and burden type), a high coal-injection rate (160-200 kg/metric ton of hot metal), advanced waste-heat-recovery and environmental systems, Level 1 automation systems in addition to Level 2 control and optimization systems. A flat casthouse floor will be provided for improved access and blast furnace operations.
Training, commissioning supervision and start-up assistance is also part of the Siemens scope of supply.
