· Iron and steel industry. 1. INTRODUCTION: Iron and Steel Industry in India is on an upswing because of the strong global and domestic demand. India's rapid economic growth and soaring demand by sectors like infrastructure, real estate and automobiles, at home and abroad, has put Indian steel industry on the global map.
Overview of steel and iron market Global steel and iron market Production output trends Over the first eight months of 2017, the global steel output reached 1,123 million tonnes, up percent from the same period in 2016. According to the EIU, midNovember will see China
In addition, iron is a critical component of peroxidegenerating enzymes and nitrous oxide–generating enzymes that are critical for the proper enzymatic functioning of immune cells. Finally, iron is likely involved in the regulation of cytokine production and mechanism of action through its influence on secondmessenger systems (Hershko 1996).

· Pure iron is a term used to describe new iron produced in an electric arc furnace where temperatures sufficient to melt the iron can be achieved. The result, also known as 'butter iron' is typically around % pure with a carbon content of around % .
emission part in steel production route due to the intensive utilization of fossil fuels for heating, melting, and reduction of iron ores. The most common ironmaking process used worldwide is the BF which produces nowadays about 70% of total world steel production. .
Coke reduces iron ore to molten iron saturated with carbon, called hot metal. • Around 1 billion tonnes of metallurgical coal are used in global steel production, accounting for around 15% of total coal consumption • Coal reserves are available in almost every country worldwide, with recoverable reserves in around 80 countries.
· The Iron Revolution in History. British iron production in 1700 was 12,000 metric tons a year. This rose to over two million by 1850. Although Darby is sometimes cited as the major innovator, it was Cort's new methods which had the major effect and his principles are still used today.

The main types of plants involved in iron and steel industry are sintering plants, blast furnaces and steel works, direct reduction plants, ferroalloy production, rolling, scarfing, pickling, iron and steel foundry, and other technologies, such as argon oxygen decarburization, ladle metallurgy vacuum degassing. Coking plants are considered here
the production of sinters or pellets. Iron ore of size less than 10 mm and ultra fines in the size range of mm to 10 mm are utilized as sinter feeds. The ores of size less than 100 mesh obtained either by grinding of high grade fines to less than 100 mesh or by beneficiating ...
process, the iron from the blast furnace is converted to steel in a basic oxygen furnace (BOF). Steel can also be made in an electric arc furnace (EAF) from scrap steel and, in some cases, from direct reduced iron. BOF is typically used for hightonnage production of carbon steels, while the EAF is used to produce carbon steels and low
The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel ...
ON THE HISTORY OF IRON AND STEEL PRODUCTION. Two steps are needed to make iron and steel – the key materials of the industrial era from iron ore. First, the ore has to be smelted in the blast furnace to produce pig iron, which is then refined in the fire to produce wrought iron or steel. Both steps are dependent on the type of fuel used.

· Steel production is a 24houraday, 365dayayear 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 (Mt) in 2001 to 1,606 Mt in 2013 and world average steel use per capita has steadily increased from 150kg in 2001 to 225 kg in 2013.
