A steel mill is an industrial factory for the manufacture of steel. And it's a metal alloy of both iron and carbon, and is maintained in a process composed of a couple of stages. The first one cares about the iron ore which gets smelted with coal and limestone in the blast furnace, maintaining melted iron which is then either posed into raw iron or moved to the second phase as melted iron.
Within the second phase which is famous as the steelmaking, the impurities like phosphorus, sulfur, and extra carbon left are eliminated and alloying substances like nickel, manganese, chromium, vanadium... etc are applied to get the desired modified metal. The largest mills in the world were in Barrow in Furness - United Kingdom. Nowadays, the largest mills in the world reside in Gwangyang - South Korea.
Mills transform the melted metal into ingots, blooms, slabs or sheets using hot rolling, casting, and cold rolling.The basic raw substances for a good working mill are as following: limestone, iron ore and coal.Those materials are altered in quantities and phases within the blast furnace where the metal compounds within the iron ore throw extra oxygen and eventually turn into the liquid form.
Like few hours later, the gathered iron liquid form is extracted from the blast furnace. After that tow things might occur: the first is pouring it into the "Pig Iron", the second is directing the liquid to different vessels for further purposes or operations. Finally steel is prepared in a good form and it can be used anywhere.
