Iron ore and metallurgical coal are used mainly in the blast furnace process of ironmaking For this process, coking coal is turned into coke, an almost pure form of carbon, which is used as the main fuel and reductant in a blast furnace
The third option for pig iron is to push the refining process even further and create steel, which we'll examine on the next page Iron Advantage Between the 15th and 20th centuries, some countries had an industrial leg up on the competition due to the availability of iron ore deposits
The Basic Bessemer process is used a great deal on the Continent for making, from a very suitable pig iron, a cheap class of steel, eg ship plates, structural sections For making steel castings a modification known as a Tropenas converter is used, in which the air impinges on the surface of the metal from side tuyeres instead of from the bottom

ITmk 3 Process of making Iron Nuggets ITmk3 process is also known as Iron making Technologies mark 3 and is based on coal reduction technologiIT mark 1 is the iron making process by blast furnace while the IT mark 2 is the iron making by direct reduction mostly by gas based reduction processes (Fig 1)
The continental Celtic origins of iron making appear to be indicated by the words “smelt” and “bloom”, both of which found their way into Old English from teutonic sourc , blast furnace sites that were dedicated to the production of wrought iron also included a third process in a building called the chafery, in effect, a forge .
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 ,
Iron Ore Smelting Process Using Modern Blast Furnac Although the basic ingredients of an iron ore blast furnace has changed little over the last hundred years or so, the furnaces themselves have been modernized to improve efficiency and the purity of the iron and steel
In the HIsmelt process, iron reduction and coal gasification take place in a liquid metal bath , New iron-making processes that use coal directly will generate a large volume of carbon monoxide, hydrogen, and hydrocarbons, which must be utilized to avoid condensation of complex and hazardous hydrocarbon compounds and improve the energy .
Deep in my January reading binge of 1998, inspired by accounts of African iron smelting and an account of the 19th century iron industry in my home county, I hatched the notion to smelt my own iron from local ore, and make a sculpture with it , A BRIEF THEORY OF THE PROCESS Here’s the basic theory of how the bloomery works As we all know .
