steel making process. steel is produced from iron ore or scrap. iron ore is a mineral aggregate that can be converted economically into iron. the quality of the iron ore is mainly determined by its composition; a high iron content and low sulphur and phosphorus contents are favorable. iron ore can be found all over the world, but its iron
the smelting and refining process for iron and steel in the bf-bof process involves the carbon reduction of iron ore in the BF to make molten iron, and decarburization of molten iron in the bof to make molten steel. major reducing agent in the BF is the carbon monoxide gas generated by the oxidation of the carbon in coke.
steel production is a 24-hour-a-day, 365-day-a-year process, dependent on a consistent supply of raw materials and huge amounts of energy. according to the world steel association, world crude steel production has increased from 851 million tonnes in 2001 to 1,606 Mt in 2013 and world average steel use per capita has steadily increased from in 2001 to 225 kg in 2013.

this is the reason why this process is employed only in industries that require high yield of steel cast. the metal is first liquefied and poured into a tundish, which is a container that leads to the mold that will cast the steel. the tundish is placed about feet above the ground level and the whole process of casting sues gravity to
galvanized steel. this steel is coated with zinc to protect against corrosion. the coating is usually done by a hot dip process. electroplated steel. this steel has a coating of another metal, usually tin, applied by the use of an electric current. tin-plated steel is widely used for making cans and other containers. tool steel.
construction of process computer systems satisfying these strin-gent requirements has been ongoing since the and at present, approximately 700 systems are operating throughout nippon steel. within this process, we will focus here on the history leading up to total self-production of process computer software, and adoption of open systems.
