process of making steel from iron ore

Steel - WikipediaSteel is an alloy of iron with typically a few percent of carbon to improve its strength and fracture resistance compared to iron. Many other additional elements may be present or added. Stainless steels that are corrosion and oxidation resistant need typically an additional 11% chromium.Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships ...How steel is made - a summary of a Blast FurnaceTo make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%."

However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

Apr 04, 2012· Perhaps the best illustration of this slow progress has been the history of the HIsmelt (High Intensity) process, promoted by its proprietor as "the world's first commercial direct smelting process for making iron straight from the ore" (Rio Tinto, 2014). Its history goes back to the development of bottom-blown oxygen converters and ...Iron ore mining and dressing - tec-scienceAn ironworks (or iron works) is an industrial plant for the production of steel from iron ores! Before the iron ores can be fed to the ironworks, they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing). These process .Iron Ore Processing for the Blast Furnacerequirements of steel customers in the blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about

This heating process is carefully controlled to make sure the resulting sinter has the right composition and optimum sizes for the next stage of the process at the blast furnaces. Making ironAn Overview of Steelmaking Process ... - steel-technologySteelmaking process involves the production of steel from iron ore and scrap. In this process, various impurities such as silicon, sulfur, nitrogen, phosphorus, and excess carbon are removed from the sourced iron. And, to produce different grades of steel, alloying elements such as nickel, manganese, chromium, and vanadium are added.How steel is made - a summary of a Blast FurnaceTo make steel, iron ore is first mined from the ground.
