It generally requires around one tonne coking coal to produce one tonne of steel. The need for iron ore is a little higher at 1.6 tonne. SAIL, which produced 92.52 lakh tonnes of saleable steel in the first nine months of the current fiscal compared to the corresponding period last fiscal, imports around 70 percent of its coking coal requirement.
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...

Jan 01, 2012· As the limited reserves of good prime coking coal deposits of the country are depleting very fast, preservation of these scarce reserves can be done by blending good prime coking coal with inferior types of coking coal for manufacturing metallurgical coke. This has warranted establishing the suitability of Assam coal for steel making.
Approximately 1.5 metric tons of metallurgical coal are required to produce 1 metric ton (1,000 kilograms) of coke. Coke in Steelmaking Basic oxygen furnaces (BOF), which account for 70 percent of steel production worldwide, require iron ore, coke, and fluxes as feed material in the production of steel.

"The national steel policy forecasts coking coal demand of 161 mtpa by 2030-31, 31 mtpa of non-coking coal for PCI, 105 mtpa of non-coking coal requirement for DRI route," Jha said. Jha said, "Thirty five per cent of total requirement of 161 mtpa coking coal by 2030-31 is about 56.35 mtpa. This is a challenge to coal and steel producers.
The most efficient steel companies have reduced their energy consumption per tonne of steel by around 60% since 1960. Today, it is estimated that the global steel industry used about 2 billion tonnes of iron ore, 1 billion tonnes of metallurgical coal and 575 million tonnes of recycled steel to produce about 1.7 billion tonnes of crude steel.
Another technology, Pulverised Coal Injection (PCI), involves injecting coal directly into the blast furnace to provide the carbon for iron-making – displacing some of the coke required for the process. A wider range of coals can be used in PCI, including steam coal which has a lower carbon content than coking coal.
Apr 24, 2013· Why is coal used to make iron and steel? Firstly coal is converted to lump coke in a coking oven. A particular rank of coal, known as "coking coal", is required to make the preferred quality of coke. Then raw iron is made by reducing (removing the oxygen from) iron ore (iron oxide) by reacting it at high temperature with coke in a blast ...

Some 25 million tons was used in the industry's sinter plants and 265 million tons in its blast furnaces to smelt 577 million tons of iron, most of which then was used in making 847 million tons of crude steel. With about 1.4 tons of coal required to make one ton of coke, the world's need for coking coal in 2000 was an estimated 475 million ...
into the blast furnace, a technology called Pulverised Coal Injection (PCI).6 One tonne of PCI coal used for steel production displaces about 1.4 tonnes of coking coal. Coals used for pulverised coal injection into blast furnaces have more narrowly defined qualities than steam coal used in electricity generation.
Jul 16, 2017· Sure, if you have non fossil fuel sources of electricity. You will need some carbon (as much as 2%) to turn the iron into steel, but that can easily come from renewable resources. Set up an electric arc furnace to supply the heat, and if you use c...
Global steel production is dependent on coal. Over 71% of the steel produced today uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. World crude steel production was 1.6 billion tonnes in 2017.
Elevated coking coal prices to crimp margins of steel producers The burgeoning dependence of domestic steel producers on imported coking coal will exert pressure on their margins. While steel prices are softening, coking coal price movements have been diametrically opposite. Coking coal is the single largest cost ingredient for a blast furnace steel operator, contributing [.]
