Coking Coal Scenario for Steel Industry of India with Specific Reference to SAIL in 10th 11th Five Year Plans

摘要

Steel making technologies and markets for steel products are rapidly changing throughout the world. Indian steel sector got a major boost since 1991 due to New Industrial Policy, throwing open the steel industry to private sector. Production of finished steel - steadily improved from 24.98 MT (98-99) to 29.7 MT(2K-01) with 7% & 11% growth during last two years respectively. The production is projected at 45 MT(2009-10) with 5-6% growth rate during 10th & 11th (2011-12) Plan. Limited availability of indigenous coking coal, its high ash content (20-21%) and difficult cleaning are key challenges for India. To achieve global competitiveness Indian steel Industry is using high percentage of low ash imported coal alongwith indigenous coking coal. These plants have also successfully substituted coking coal by coal dust injection in blast furnace. The paper elaborates on the requirement of coking coal, its qualities and coking properties by 2006-07 and 2011-2012 (11th Five Year Plan) with reference to the Indian Steel Industry.
