Blast Furnace Constructions, Rebuilds & Relines
Introduction
Tata Steel’s capacity expansion project reached a new milestone on 4 April 2012 with the successful commissioning of the new blast furnace “I” at the Jamshedpur works in Jharkhand.
In October 2008, Tata Steel had awarded the Paul Wurth Group, in association with its local partner Larsen & Toubro, with the contract for the turn-key construction of the new BF “I”. With an inner volume of 3 814 m3 and an annual production capacity of 3 million tons of hot metal, BF “I” largely repeats the plant configuration of BF “H”, with even improved performances resulting from the use of a high rate of pellets, increased oxygen enrichment and en-hanced pulverised coal injection capacity.
Project Realisation
Blast furnace “I” has been designed, manufac-tured, 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 tech-nology, the furnace is equipped with copper and cast iron stave coolers and features a new gen-eration Bell Less Top® charging system. Two flat casthouses operating four tapholes are fitted with fully-hydraulic TMT casthouse machines. The high-performance hot blast stoves with internal combustion chamber are equipped with a heat recovery system, using the waste heat from the stoves’ exhaust for savings in fuel consumption. Energy in terms of electrical power is also recov-ered from the BF gas through a top gas pressure recovery turbine. Finally, the scope of Paul Wurth supplies also includes a pulverised coal injection system and two INBA® slag granulation plants.
Thanks to the new BF “I” with an expected cam-paign life of 20 years, Tata Steel will be able to increase the steel production of its Jamshedpur steelplant to 10 million t per year.
After the modernisation of blast furnaces “F” and “G” and the newly built “H” unit, number “I” is the fourth blast furnace installation at Jamshedpur which enters Paul Wurth’s reference book.
