Steel is the worlds most fundamental engineering and construction material. up to 500 million GJ, and Slag 400kg. 170kg billion tonnes, as well as cutting coal consumption by 18 billion tonnes. Recycling one tonne of steel . scrap saves tonnes of CO 2
From the data in Table 1 and Fig. 3 it is apparent that the production of hot metal or pig iron is the most energy intensive process for steel production at roughly #215; 10 9 joules per ton (1000 Kg) of pig iron produced. The basic oxygen furnace is the second most energy intensive process at 11 #215; 10 9 joules per ton or steel produced. The Electric arc furnace has significantly less energy
National Steel Policy2017 envisages a requirement of 161 million tons of Coking Coal and 31 million tons of Coal for PCI by 203031. As per the targets fixed by NSP, the present level of PCI which is around 50150 Kg per ton of hot metal has to increase to 180200 Kg and coke rate from 450600 kg has to be reduced to 300350 Kg per ton of hot

million tons less if the electricity conversion factor for CE units used in this report assumed the national grid generation based on 60 percent coal, 11 percent natural gas, and 29 percent noncarbon requirement of 1 million tons of steel annually. However, steel interests have faced serious threats from foreign competitors.
Aug 29, 2019#0183;#32;According to company records, Tata Steel produced tons of ironore from its captive mines during 2018/19 and tons of coal. The steel producer was almost fully self reliant in ironore from its captive mines, which provided it with raw material security and cost of production advantages, while its captive coal mines met
Jun 22, 2016#0183;#32;ET Bureau. KOLKATA: Domestic steel producers are likely to require close to 96 million tonne of coking coal by FY2020, with the country''s crude steel capacity expected to grow to 173 mt in the next four years, a sector report has said. The steel sector is already the second largest consumer of coal in India accounting for nearly 8% of coal consumption.
requirement of sponge iron production. Today India produce million tons of sponge iron, out of which million ton is gas based and remaining million ton is coal based. India has a proven reserve of 410 million ton of high grade iron ore, another 440 million ton of high grade iron .
Around 150 kg of coal are used to produce 1 tonne of steel in electric arc furnaces. Other steel production methods Pulverised coal injection. Pulverised Coal Injection (PCI) technology involves injecting coal directly into the blast furnace to provide the carbon for ironmaking
Steel is manufactured predominantly using two methods. Both methods of production require a significant input of scrap steel. The primary route uses % scrap, with emissions of tonnes of CO2/tonne of steel. The secondary route uses 105% scrap steel, with emissions of tonnes CO2/tonne.
consumption of about million metric tons of concrete, million metric tons of steel, 310,000 metric tons of cast iron, 40,000 metric tons of copper, and 380 metric tons of the rareearth element neodymium. With the exception of neodymium, these material requirements represent less than 3 percent of the apparent consumption for 2008.
