 — Companies like SSAB have developed plans to eliminate coal from their steel plants. In place of coke, derived from coal, the company plans to use clean hydrogen. Like carbon, hydrogen can also strip oxygen from iron ore to make the pure iron needed in steel-making. But in this reaction, the resulting "emission" is H20. Photo: SSAB

Steelmaking furnaces are used to make different types of steel that contain lower carbon content, usually less than 1%, and alloys. ... Coke Making. Coal processing typically involves producing coke, coke gas, and by-product chemicals from compounds released from the coal during the coke making process. Coke is carbon rich and used as a carbon ...

 — In the steel-making process, coke is used in the blast furnace as a (1) fuel to produce added heat; (2) chemical-reducing agent for the reduction of iron oxides; and (3) as a permeable support in the molten material in the furnace.

In 2019, about 23 percent of all electricity in the United States was generated by coal-fired power plants, according to the U.S. Energy Information Administration.Certain types of bituminous coal can also be used in making steel. Coal used for steel making needs to be high in carbon content and low in moisture, ash, sulfur, and phosphorous ...

In the steel-making process, metallurgical coke is the major ingredient second to iorn ore. Coal is also often burnt in steel industries to supply power to power to this highly energy-intensive industry. Coal is converted into metallurgical coke for use in the blast furnaces of steel-making industries across the globe.
