04/04/2012  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 combined steelmaking by Klöckner Werke in the early ...

Iron processing - Iron making Britannica

Iron processing - Iron processing - Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

How iron is made - Forestry and Land Scotland

The iron-making process develops. Iron-making reached Britain from Europe and the Middle East around 450 BC. At this time the process only needed iron ore, charcoal and clay. Water power was used to power bellows and hammers from the 13th century, and the blast furnace was introduced in the 15th century in Belgium. Charcoal was used where there was timber in ready supply but for the areas ...

Manufacturing Process of Cast Iron Castings

Cast iron begins its life as pig iron, which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron, and the iron, once melted, is then cast. Casting is the process of pouring the iron into a mold thus giving it a shape. Molds and pouring methods divide this process up. Molds can be made as expendable molds ...

Ancient iron production - Wikipedia

Ancient iron production refers to iron working in times from prehistory to the early Middle Ages where knowledge of production processes is derived from archaeological investigation. Slag, the byproduct of iron-working processes such as smelting or smithing, is left at the iron-working site rather than being moved away with the product. It also weathers well and hence it is readily available ...

Iron Making Boundless World History

Carburization is a heat treatment process, in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder. Unlike modern steel making, the process increased the amount of carbon in the iron. Second Industrial Revolution

Corex Process for Production of Iron – IspatGuru

Corex process distinguishes itself from the blast furnace route by (i) direct use of non-coking coal as reducing agent and energy source, (ii) Iron ore can be directly and feasibly charged to the process in form of lump ore, and pellets, and (iii) use of pure oxygen instead of nitrogen rich hot blast. Direct use of non-coking coal is possible since the coal is charred inside the melter ...

Steel Production - American Iron and Steel Institute

The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are ...

Creating Steel HowStuffWorks

Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter.The heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.
