Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes 5 percent by weight of the Earths crust, and it is
account for more than 90% of the world production of iron and steel powders, viz. the Hgans sponge-iron process and the water-atomizing process. The former process is based on reduction of iron ore, yielding a highly porous sponge-iron which subsequently is comminuted to powder. The latter process is based on atomization of a stream of liquid
There is also an alternate steelmaking process called HIsarna ironmaking. In HIsarna, iron ore is processed immediately into hot metal. The blast furnace used is a cyclone converter furnace, which skips the making of iron pellets. This skipped step makes the entire process far more energy-efficient and lowers the carbon footprint of steel ...

Properties of Iron and Steel Industry Since last century, volume of steel production of a nation was taken as an index of industrial development. Among all the manufacturing industries, iron and steel industry holds an enviable position.
The figure shows a flowchart of the integrated manufacturing process for iron and steel using the blast furnace and basic oxygen furnace (denoted BF and BOF hereinafter, respectively), which is presently the most commonly used method (51% of world steel production).
The Manufacturing Process First, each sub-assembly of the iron is produced, most often on separate, automated production lines. Then the iron is assembled. Sole plate 1 The sole plate is cast of molten aluminum. Part of the mold creates the holes that are essential in a steam iron. Heated metal is inserted into a mold under pressure, cooled ...
The book on Manufacturing Processes covers a wide overview of material, manufacturing processes and other misc. topics. Unit-I deals with Basic-Metals alloys Properties and Applications. Units-II and III cover major manufacturing processes such as Metal Forming Casting and Machining Welding. The last
Apr 13, 2020 Infographic the Iron and Steel Manufacturing Process. 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.
Manufacturing Process of Cast Iron Castings . The making of cast iron begins with a combination of raw materials. Iron is rarely found in its pure form. Only meteorites contain pure iron. The iron in use for centuries is found in the combination of iron and other elements. These combinations are known as iron oxides.
