they invented the first inexpensive industrial process for the mass-production of steel from molten pig iron. The process is named after its inventors, who took out a patent on the process in 1855. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.
In past times most often the blacksmith used wrought iron. Wrought iron is made by taking iron ore and charcoal heating until it melts. That process produces pig iron. The next step is to heat the pig iron up until it is soft then hammer it until most of the impurities are driven off. Iron as it is heated past 600 degrees F turns black as the iron oxides with air. That gives the Blacksmith his name black + smith or striker. Mild steel is used for most modern blacksmith works.Mild steel that is steel that has less than .3 percent carbon in it. Cast iron is not used as it is too brittle.
According to Wikipedia Online Encyclopedia (http://en.wikipedia.org/Bessemer_process) "The Bessemer process was the first inexpensive industrial process for the mass-production of steel from molten pig iron."
The Mesabi Range of Minnesota provided most of the iron ore for America's steel industry.
To 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%."
It is called the Bessemer process. Iron has particles in it and air is blown into the molten iron to get rid of the impurities in the iron. It becomes steel.
The Bessemer process was the first inexpensive industrial process for the mass-production of steel from molten pig iron. The process is named after its inventor, Henry Bessemer, who took out a patent on the process in 1855. The process was independently discovered in 1851 by William Kelly.
The process of transforming iron into steel is called "steelmaking" or "steel production." It involves removing impurities from iron and adjusting the carbon content to create the desired properties in the steel.
I don't think anybody wants to change steel to iron. However, changing iron to steel is done a lot because steels (of which there are many variants) have properties superior to iron. For example, manganese steel is what railway lines are made of and they are tough and not brittle, ideal for this purpose. Mild steel, which is very commonly used for 'iron' objects has some carbon in it which gives it good properties for everyday use. Stainless steel has chromium in it which gives it anti-rust properties.
The pig iron is converted into steel through a process called the basic oxygen steel making.
Steel does not come out of the ground. It is the Iron Ore which is a Major Raw Material in Steel Preparation Process that is mined out of the earth. The mining of iron ore from the earth is a process in itself.

Iron ore is processed and converted into steel by steel mills. The process involves extracting iron from the ore through smelting and refining it to remove impurities. The molten iron is then cast into various shapes and cooled to form the final steel product.
iron and steel rusts the most because of a process called oxidation. if the minerals that are in iron and steel mix with the oxygen in the air, the minerals will react by forming rust.
Henry Bessemer developed a way to make steel by melting and burning pig iron. Pig iron is the result of mining and refining iron ore. Before steel, he worked with glass, but his glass making process was not practical.
The process of making iron strong enough to use for weapons was developed by ancient civilizations, such as the Hittites and Egyptians, through a technique called carburization. This involves adding carbon to the iron to create steel, which is stronger and more durable than pure iron.
