Genova, 3 December 2008. Just less than 6 months after commissioning the new blast furnace “H” at their Jamshedpur plant, TATA STEEL broke ground for the construction of the next modern ironmaking unit.
Tata Steel placed a related order for design, supply, erection and commissioning of blast furnace “I” to Paul Wurth Italia, Paul Wurth India, and Larsen & Toubro.
The blast furnace “I” will have an inner volume of 3,814 m3. It largely repeats the plant configuration of blast furnace “H” including proven solutions and state-of-the-art technology: The blast furnace proper with copper and cast iron stave coolers, and the new GEN2 two-hopper Bell Less Top® charging system. Two flat castfloors with four tapholes are fitted with TMT full-hydraulic 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 recovered from the BF gas through a top gas pressure recovery turbine. Finally, the scope of Paul Wurth supplies also includes a pulverized coal injection system and two INBA® slag granulation plants.
Tata Steel intends to operate the blast furnace “I” on a production rate of 3 million tons of hot metal per year. It is planned for start-up in February 2011.
After the modernizations of blast furnaces “F” and “G” and the newly built “H” unit, number “I” will be the fourth blast furnace installation at Jamshedpur which enters Paul Wurth’s reference book.
