The world now needs to make more steel to help build almost everything. And to this day, there still isn''t any better industrial method for producing steel in mass quantities without using coking coal. Second only after iron ore, it is the most vital ingredient required in the steelmaking process – via the integrated blast furnace route.
One of the highest grades of coal is metallurgical coal or coking coal. It forms one of the key inputs required for the production of steel (mainly used in iron and steel making industries). 70% of the steel produced today uses coal. In 2010, world crude steel production was billion tonnes, requiring 721 million tonnes of 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 ...
Approximately 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.
Naturallyoccuring iron ore varies in it''s content. Also, you haven''t said whether it is "benefacted ore" (crushed, with gangue material removed), or straight out of the ground. Obviously, if the latter is the case, even very rich ores seldom cont...
Sep 03, 2019· Global steel mill margins have shrunk in 2019, in turn pushing down iron ore and coke consumption and prices for coking coal. In 2018 Platts benchmark US hot rolled coil (HRC) spot prices exceeded 1000/mt delivered Midwest for the first time since 2008, and the sustained run in steel pricing and demand since 2016 delivered high profits for 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 billion tonnes of crude steel.

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 billion tonnes in 2017.
input from coal accounts for 11%, from electricity 50%, from natural gas 38% and 1% from other FACT SHEET Energy use in the steel industry The steel industry actively manages the use of energy. Energy conservation in steelmaking is crucial to ensure the
Jul 16, 2014· Another wellknown process of steel making is completed with an electric arc furnace. Unlike a blast furnace, an electric arc furnace uses no iron in steel making. Coke and coal are not required during this process, as it uses electricity instead. Coke is often produced away from the steel mills, and is often delivered via railway.
Nov 18, 2012· steel production, coking coal – World Coal Association. Iron Making Iron ore is mined in around 50 countries . Around 150 kg of coal are used to produce 1 tonne of steel in electric arc furnaces. Pulverised Coal Injection. »More detailed
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 [.]
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 ...
Given that about 770 kg of coking coal is required to make one tonne of steel, the more than tripling of prices since this year''s rally took off in July will be causing pain for steelmakers, who ...
Blending of Coal: Because of limited availability of good quality coking coal, the Indian Steel plants use a optimal Blend of the 3 or more varieties of coking coal to compensate for the lack of individual coals with the necessary properties. Another important consideration in selecting a coal blend is that it should not exert a high coke oven ...

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 tons of coal required to make one ton of coke, the world''s need for coking coal in 2000 was an estimated 475 million ...
providing the necessary carbon for the steel alloy. >> Definition Coking coal is defined as hard coal with a quality that allows the production of coke suitable to support a blast furnace charge. Coking coals have a higher carbon content than steam coals, which are mainly used in electricity generation. Coal Fact 1 tonne of coking coal produces ...
