  How iron is made - material, manufacture, making, history, …

  Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further …

  Coal to Make Coke and Steel - University of …

  2016622 · Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880’s, steel was produced using charcoal.

  Fact sheet Hydrogen (H2)-based ironmaking - Steel

  2022629 · Carbon combines with the oxygen in the iron ore, producing metallic iron and a carbon-rich process gas, according to the following simplified chemical reaction: 2Fe2O + 3C -> 4Fe + 3CO. 3 2. It is also possible to reduce iron ore using hydrogen instead of carbon; in this case the waste gas produced is water, as per the following reactions: H2 ...

  Steps in the Modern Steelmaking Process - ThoughtCo

  2020821 · Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.
