Manufacture of Reinforced Steel Bars and Wire Rods. This research will begin with the figure that 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). After the BF - BOF process, molten steel is controlled to a target composition and temperature and is then cast by continuous casting machine to produce bars and wire rods. These castings are rolled to the required dimensions by the rolling mill to produce steel products to produce reinforced steel bars. The wire rods too are welded thereafter to produce the required reinforced steel mesh. The smelting and refining process for iron and steel in the BF - BOF process involves the carbon reduction of iron ore (Fe2O3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel.

In addition to the BF - BOF process, there is another process which utilizes mainly scrap as an iron source, with some direct reduced iron whenever necessary. The direct reduced iron is produced by reducing iron ore with reformed natural gas, whose principal components are hydrogen, carbon monoxide, and methane. The scrap, along with direct reduced iron, is then melted in an electric arc furnace (denoted EAF hereinafter) to produce molten steel which is subsequently processed by the continuous casting machine, as mentioned above. The molten steel from the BOF and EAF is then deoxidized and alloying elements are added in the prescribed amounts. The molten steel is then held at the target temperature and continuously cast, and the castings obtained are cut to the prescribed length. After heating to the rolling temperature in a reheating furnace, these castings are hot-worked to the required products. Bars and wire rods are worked on section and bar mills and wire-rod mills equipped with caliber rolls. Manufacture of Reinforced Steel Bars and Wire Rods.
