Genova / Luxembourg, 2 June 2008. On 31st May 2008, TATA Steel successfully commissioned its new blast furnace ‘H’ at its Jamshedpur works in Jharkhand. With an inner volume of 3800 cubic meters and a daily production of 7200 tonnes of hot metal, this new blast furnace is the biggest one ever built in India.
Blast furnace ‘H’ has been designed, supplied, erected and commissioned by a consortium consisting of Paul Wurth Italia, Paul Wurth India, and Larsen & Toubro.
Integrating state-of-the-art Paul Wurth technology, blast furnace ‘H’, which is cooled with copper and cast iron staves, features a new generation Bell Less Top® charging system. Two flat casthouses operating four tapholes are fitted with TMT* casthouse machines. The high-performance hot blast stoves with internal combustion chamber are equipped with a heat recovery system, recovering the waste heat from the stoves’ exhaust so as to save on the fuel rates. Energy in terms of electrical power is also recovered from the BF gas through a top gas pressure recovery turbine. Finally, the scope of Paul Wurth supplies also included a pulverized coal injection system and two INBA® slag granulation plants.
Thanks to the excellent cooperation between all participants, the project has been completed in 25 months from the groundbreaking, which is the shortest possible time ever taken for building a blast furnace of such size.
Presently, the Paul Wurth Group is involved in no fewer than three major blast furnace projects in India: Rashtriya Ispat Nigam Ltd asked Paul Wurth to undertake the turnkey construction of its new No.3 blast furnace at the Visakhapatnam site, Bhushan Steel Ltd commissioned the Group to build its new No.2 blast furnace at Orissa Angul and, lastly, SAIL Bokaro Steel Plant gave Paul Wurth the task of relining of its No.2 blast furnace.
