With the commencement of the blow-in process, Tata Steel on Tuesday inaugurated its upgraded C-blast furnace. Structured on the lines of the steel major?s 10 mtpa expansion by mid-2011, it would now have a capacity to produce 0.7 million tonne per annum (mtpa), up from its last capacity of 0.4 mtpa. The entire upgradation process has been designed and implemented internally for the first time at its Jamshedpur works here. With the blowing-in taking place today in the presence of Tata Steel executive director (India & South East Asia) H M Nerurkar, it also became the first steel company in the world to incorporate ?Gimbal? technology in the furnace. The technology, sourced from Seimens, is primarily for the purpose of providing total flexibility in material distribution, enabling customers to make significant cost savings and benefit from improvements in blast furnace operations and maintenance. Tata Steel?s C-blast furnace is a part of its A to F blast furnace chain within its Jamshedpur steel works. Nerurkar said, ?The re-modelled C-blast furnace compliments the technical know-how and dedication of both Seimens as well as Tata Steel teams; I?m sure that our operations at C-blast furnace and production as a whole will now greatly be enhanced.?
