A diagram of the slag pit furnace. These non-tapping furnaces were used for bloomery smelting. Figure 4 Iron billet. The iron blooms made by bloomery . smelting had to be smithed before they could be used, to remove trapped slag and air. Then the iron was shaped into objects or a form of trade iron, such as a billet, ingot or bar.
Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from to inches. This ore is either Hematite (Fe 2O 3) or Magnetite (Fe 3O 4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into

Draw a flow diagram for the process you have designed. Consider using a number of steps in different orders. You may use the same technique more than once. Iron ore, a type of coal called coke (which contains 85% carbon) and lime are added to the top of the blast furnace.
03-06-2022 · A new route for making steel from iron ore based on the use of hydrogen to reduce iron oxides is presented, detailed and analyzed. The main advantage of this steelmaking route is the dramatic reduction (90% off) in CO2 emissions compared to those of the current standard blast-furnace route. The first process of the route is the production of hydrogen by water …
