    Jun 21 2018 Direct reduced iron DRI process. In addition to the process route via the blast furnace process there is another option for extracting crude steel from iron ores using the so-called direct reduced iron DRI process secondary route.The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

    Steel making process ArcelorMittal

    There are two main processes for producing steel by means of a blast furnace indirect reduction in combination with a converter or by means of an electric furnace. In the former process iron ore is the main raw material. In an electric furnace scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product which.

    Iron and Steel Statistics and Information USGS

    By definition steel is a combination of iron with a small amount of carbon. Thousands of products having various chemical composition forms and sizes are made of iron and steel by casting forging and rolling processes. Iron and steel comprise about 95 percent of all the tonnage of metal produced annually in the United States and the world.

    Metal Passivation Preventing Iron amp; Steel from Getting

    Gun bluing was an early example of forced passivation through chemical manufacturing means. One of the oxides of iron is magnetite a black oxide Fe3O4 and this oxide does not flake the way rust Fe3O3 will. Several chemical processes can be used to create these black oxides using heat and caustic solutions.

    Mar 13 2010 The pig iron can be further refined to produce steel or wrought iron. Both these methods reduce the carbon content of the pig iron which in turn reduces the brittleness property of the metals. Wrought Iron Process. Wrought iron is produced by pummeling the pig iron using mechanically driven hammers in a wrought iron works.

    Jun 04 2015 Steel is made primarily in a two-step process. In the primary steelmaking step liquid iron is converted into steel by the basic oxygen furnace BOF process or by melting scrap steel or direct reduced iron DRI in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.
