An iron resource efficiency is proposed to define a measure of the natural iron resources saved in the steel manufacturing process. A simplified iron flow diagram is The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas (CO) generated by the oxidation of the carbon (C) in coke1A Manufacturing Process for Iron and Steel

Cast iron is one of the initial products in the manufacturing process, and its flow chart shows the importance of cast iron in the steel industry. Cast iron belongs to the family of ferroalloys and is one of the most widely used alloys in the industry. Iron, carbon and silicon are the main elements of this alloy.3.2 Production Process In the iron and steel plant, supply of raw materials and fuel from raw materials pre- quantity of material flow between the production plants, power plants, ancillary fa-cilities, residential areas, establish the material flow start and end table, letters on ship diagram can be seen the relationship level of eachOverall Layout Design of Iron and Steel Plants on SLP

Direct Reduced Iron (DRI): This iron production process directly reduces iron ore in solid-state with the reaction temperature below the melting point of iron. Reducing gases are produced from natural gas capacity. The process flow diagram (PFD) of the sponge iron process is shown in Fig. 1. Different streams in the PFD are assigned individual number and henceforth each stream will be referred through its respective number. Detailed operation of this plant is discussed in the work of Prasad et al. [2011]. The operating parameters for this processCASE STUDY ON THRESHOLD PROBLEM Sponge Iron
