1a Manufacturing Process For Iron And Steel The smelting and refining process for iron and steel in the bfbof 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 major reducing agent in the bf is the carbon monoxide gasco generated by the oxidation of the carbonc in coke Iron Processing Britannica Ironprocessing use of a smeltingprocessto turn the ore into a form from which products can be fashionedincluded in this article also is a discussion of the mining ofironand of its preparation for smeltingironfe 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 the Process For Manufacturing Of Iron Carbide Ispatguru Mar 11 2018 it reducesironore toironcarbide in a fluidized bed reactor by contacting theironore withprocessgas consisting primarily of methane ch4 and hydrogen h2 theprocessfor themanufacturing ironcarbide was originally designed and developed at hazen research inc in golden colorado usa by the technical vice president dr frank m 1amanufacturing Processforiron And Steel The figure shows a flowchart of the integratedmanufacturing processforiron and steelusing the blast furnace and basic oxygen furnace denoted bf and bof hereinafter respectively which is presently the most commonly used method 51 of worldsteel production after the bfbofprocess moltensteelis controlled to a target composition The Modernsteel Manufacturing Process Thoughtco Aug 21 2020 the modernsteel production processmethods formanufacturing steelhave evolved significantly since industrialproductionbegan in the late 19th century modern methods however are still based on the same premise as the original bessemerprocess which uses oxygen to lower the carbon content iniron
