Emerging Technologies for Iron and Steelmaking

Pre-reduced iron ore coal and oxygen are injected into a deep steel-making slag The coal is devolatilized and partially combusted to CO The uncombusted coal char either directly reacts with iron oxide dissolved in the slag to form iron and carbon monoxide or dissolves in the iron bath Get price



What we find instead is iron ore which is iron (Fe) in one of two oxidized forms Fe2O3 (hematite) or Fe3O4 (magnetite) In order to refine these into anything useable they need to be reduced normally by adding carbon at high temperature By getting the carbon C to react with the oxygen O in the ore Get price


How steel pipe is made

1 Molten steel is made by melting iron ore and coke (a carbon-rich substance that results when coal is heated in the absence of air) in a furnace then removing most of the carbon by blasting oxygen into the liquid The molten steel is then poured into large thick-walled iron molds where it cools into ingots Get price


How Is Iron Extracted From the Earth?

How Is Iron Extracted From the Earth? Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however because iron does not occur naturally it is necessary to use a blast furnace Get price



This section deals with the types of iron and steel which are produced as a result of the steel-making process Wrought iron If all the carbon is removed from the iron to give high purity iron it is known as wrought iron Wrought iron is quite soft and easily worked and has little structural strength It was once used to make decorative gates Get price


How is Iron Made Into Steel?

Iron was the dominant metal for use in building and machinery until the modern era Iron is still the main component of steel but when impurities are removed in the steel-making process a stronger lighter material results (steel) Steel is used in almost all modern buildings automobiles aircraft and appliances Get price
