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.
Modern methods however are still based the same premise as the Bessemer Process namely how to most efficiently use oxygen to lower the carbon content in iron Modern steelmaking can be broken down into six steps 1 Ironmaking In the first step the raw inputs iron ore coke and lime are melted in a blast furnace The resulting molten iron also referred to as hot metal still.

Aug 12 2008nbsp018332Woodward Iron Company Four iron making enterprises each controlling substantial deposits of iron ore coal limestone and dolomite came to dominate the industry These companies were unique in their use of advanced blast furnace plants that smelted iron ore into pig iron Woodward Iron Sloss Sheffield Steel and Iron Company and Thomas Works operated blast furnace plants that.
Production routes for steel Dutch Pavilion at World Expo 2010 John K246rmeling There are basically two routes for the production of steel In the Blast Furnace route BF pig iron is extracted from iron ore using coke Slag and blast furnace gas are formed in the blast furnace.
However the basic technique was simple and the use of iron gradually spread As useful as it was compared to other materials iron had disadvantages The quality of the tools made from it was highly variable depending on the region from which the iron ore was taken and the method used to extract the iron.
The first step in the production of steel or cast iron alloys is the reduction of iron ore which contains iron oxide and gangue or mineral impurities to unrefined hot metal or pig iron The blast furnace is currently the key tool for ironmaking.
Sep 03 2019nbsp018332Unlike integrated steel mills which make new steel from iron ore in a blast furnace mini mills melt and refine scrap steel using electric arc furnace EAF technology According to a U S Environmental Protection Agency EPA report while mini mills accounted for 10 percent of U S steel production in 1970 by 2006 over half of the national.
