India to double domestic steel making capacity by 2030


India is all set to double its steel making capacity in the next nine years by providing policy support and guidance to steel producers.

Official sources, quoting Union Minister of Steel Ram Chandra Prasad Singh, said the present annual crude steel capacity of the country is 144 MT and is envisaged to reach 300 MT by 2030-31.

The priority for this sector is evident from the fact that 40 per cent of investment in manufacturing sector in India has been made by companies in the steel sector during 2020-21. Further, after analysing the data, several initiatives have been taken by the Ministry of Steel to increase usage of domestically manufactured steel and import substitution.

Joint Plant Committee (JPC) and Institute for Steel Development and Growth (INSDAG) along with Ministry of Steel have evolved a roadmap for increasing the use of steel in various infrastructure sectors.

Steel Authority of India Limited (SAIL) and Rashtriya Ispat Nigam Limited (RINL) have adopted the Best Available Technologies (BAT) available globally, in the modernisation & expansions projects and improved Techno-economic parameters such as reduction in coke rate, increase in Pulverised Coal Injection (PCI) rate, improvement in BF productivity etc. resulting in reduction of CO2 emission intensity from a level of 3.1 t/tcs from 2005 to 2.55 t/tcs in 2021.

List of Best Available Technologies deployed are as under.

Best Available Technologies (BATs) adopted by SAIL and RINL are given below:-

* Coke Dry Quenching Technology to recover sensible heat from coke from Coke Oven Batteries to produce electricity.
* Top Pressure Recovery Turbine in Blast Furnaces to recover waste Pressure energy of BF gas to electricity.
* Sinter Cooler Waste Heat Recovery System in Sinter Plant to produce steam or electricity.
* Blast Furnace Hot Stoves Waste Gas Recovery System to utilize the waste to preheat the air entering to stoves. Further, the waste gas at reduced temperature is used to pre heat BF gas & Combustion air.
* LD Gas recovery system in Steel Melting Shops to recover LD gas from converter blowing for usage as fuel in reheating furnaces.
* Evaporating cooling system in reheating furnaces of rolling mills to generate process steam.
* Recuperators/ Pre-heaters to recover sensible heat of waste gases from Rolling Mills Reheating Furnaces and Calcination plant kilns.
