EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

In 2012 Tata Steel Ltd, commenced construction of an integrated iron and steel plant in Kalinganagar Orissa, India. The first phase of the project included steelmaking facilities, coke plant, sinter plant and blast furnace number 1. A contract had been awarded to Primetals Technologies in January 2007 to design and supply the new 14m hearth diameter blast furnace and additional facilities as part of the overall site arrangement. The project included the supply of equipment required for a modern free-standing blast furnace including a copper stave cooling system, a flat floor casthouse arrangement, bell-less top charging facilities, and a full suite of blast furnace unit equipment. Also supplied were wet slag granulation facilities, three external combustion chamber hot blast stoves and a gas cleaning plant with top gas recovery turbine arrangement. The blast furnace blow-in occurred on the 29th February 2016 and has design capability to supply up to 9,150 tons of hot metal per day. This paper will discuss the project scope and highlight some of the design features such as pneumatic dust conveying, cyclone and dustcatcher combination, trough forced cooling, latest stove crossover design. Some of the challenges faced through the various phases of the project (design, supply, construction, commissioning and operation) will also be reviewed.
