Iron is extracted from the earth as a metallic ore. Then it is processed in a steel mill. Since that moment, it is called "steel".
During the manufacture of Cast Iron, an intermediate product is Pig Iron. Further processing results in Cast Iron.
Iron oxide blue is an old fancy suited for a veriety of iron oxide pigments such as rouge, mars black etc., in which common adotance of the term oxide is used whenever iron oxide is not present in the final formula but might find sues in the manufacture of the pigments.
The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.
It was Sir Henry Bessemer who patented the process in 1856 to take pig iron disturbed by a current of air to turn it directly into steel. Andrew Carnegie, a Scottish immigrant, was able to use the Bessemer process in his steel mills after the civil war to create the largest iron/steel works in America.
Nodal industries are those industries around which other peripheral industries also develop. These peripheral industries manufacture the goods required by the nodal industries. An iron and steel industry is a typical example of a nodal industry.
