  • Abstract

    The Indian steel industry has matured well over the past century. From just a one million tonne capacity at the time of independence, it has risen to be the 2nd largest crude steel producer and the largest producer of DRI in the world now. The past decade has seen almost a two-fold increase in crude steel production from 63 MT in 2009 to 112 MT in 2019. For sustained growth, it must be accompanied by technological improvement and Indian steel industry is a living testimony of this concept. Extracting value from depleted and low-grade raw material, increasingly stringent environmental regulations driven by inevitable concern of climate change and rising customer expectations are forcing the steel industry to re-invent itself. The Indian steelmakers have successfully experimented with DRI addition as part of the solid charge in BOF steelmaking. Use of advanced technologies such as sub-lance for in-blow measurements have also become a reality. CAS-OB technology in secondary steelmaking combines low investment costs, high refining efficiency and simple operation. This past decade has seen successful stabilization of this technology. Gradual shift from un-safe CaC2 to CaO as a desulfurization reagent and increased recycling of LF and LD slag are favourable steps taken towards safe and sustainable steelmaking. The move towards digitization has led to Industry 4.0 which uses the Internet of Things and cyber-physical systems such as sensors having the ability to collect data that can be used for monitoring and control purposes. The recent advancements in big data and powerful analytics means that systems can dive through the huge sets of data and produce insights that can be acted upon quickly, almost in real-time. This article provides just a few instances of the technological growth seen by the Indian steel industry, with illustrations at Tata Steel, in the past decade.
