Iron

The raw materials used to produce pig iron in a blast furnace are iron ore coke sinter and limestone Iron ores are mainly iron oxides and include magnetite hematite limonite and many other rocks The iron content of these ores ranges from 70% down to 20% or less Coke is a substance made by heating coal until it becomes almost pure carbon Get price

Hand Forged

The introduction of coke for use in the blast furnace by Abraham Darby In 1709 (or perhaps others a little earlier) initially had little effect on wrought iron production Only in the 1750s was coke pig iron used on any significant scale as the feedstock of finery forges However charcoal continued to Get price

Iron and steel desulphurization

The invention relates to the manufacture of pig iron and the production of steel and particularly to the desulphurization of pig iron A purpose of the invention is to lower the cost of pig iron production in the coke blast furnace by operating the blast furnace at lower temperature and/or with less basic slag thus obtaining pig iron Get price

Iron in the Industrial Revolution

While Britain had good iron ore reserves the iron produced was of low quality with plenty of impurities limiting its use There was plenty of demand but not much was produced as wrought iron which had many of the impurities hammered out took a long time to make and was available in cheaper imports from Scandinavia Get price

What year did iron technology begin?

Worked iron has been known from both the Middle East and China from perhaps 3 000 BCE This was made from nickel iron - thus derived from meteorites But some evidence gives us Chinese blast furnaces from as early as 500 BCE A simple charcoal fuelled furnace may smelt iron ore into pig iron but this is over-rich inGet price

The steel story

In 1865 French engineer Pierre-mile Martin took out a license from Siemens and first applied his regenerative furnace for making steel Their process was known as the Siemens-Martin process and the furnace as an 'open-hearth' furnace in which excess carbon and other impurities are burnt out of pig iron to produce steel Get price

Image

Bloomery

When combined with the strong air blast required to penetrate the large ore and charcoal stack this may cause part of the iron to melt and become saturated with carbon in the process producing unforgeable pig iron which requires oxidation to be reduced into cast iron steel and iron This pig iron was considered a waste product detracting Get price

Image

Iron and steel

Other Methods of Iron Refining Although almost all the iron and steel manufactured in the world is made from pig iron produced by the blast-furnace process other methods of iron refining are possible and have been practiced to a limited extent One such method is the so-called direct method of making iron and steel from ore without making pig Get price

Lime an essential component in the steel industry

Pig-iron This is liquid iron which because it is denser accumulates at the bottom and must be extracted from the furnace and transported to the foundry or the Steel mill (Secondary Steel making) As seen above pig-iron is iron carbon and is called the first casting or initial smelting Get price

Image

Pig iron

Pig iron is an intermediate product of the iron industry also known as crude iron which is obtained by smelting iron ore in a blast furnace Pig iron has a very high carbon content typically 3 8–4 7% along with silica and other constituents of dross which makes it very brittle and not useful directly as a material except for limited Get price
