Integrated steel plants are large, handle everything in one complex from putting together raw material to steel making, rolling and shaping. Iron ore, coke, and flux are fed into the blast furnace and heated. The coke reduces the iron oxide in the ore to metallic iron, and the molten mass separates into slag and iron. Some of the iron from the blast furnace is cooled, and
This book describes improvements in the iron and steel making process in the past few decades. It also presents new and improved solutions to producing high quality products with low greenhouse emissions. In addition, it examines legislative regulations regarding greenhouse emissions all around the world and how to control these dangerous emissions in iron and steel making plants. Keywords
Global iron and steel market Production. Over the last 35 years, the iron and steel industry has seen significant changes. In 1980 716 mln tonnes of steel was produced and the following countries were among the leaders: USSR (21% of global steel production), Japan (16%), USA (14%), Germany (6%), China (5%), Italy (4%), France and Poland (3%), Canada and Brazil (2%).
4 Introduction to Iron and Steel A few definitions and general descriptions are in order Pig iron: Raw iron, the immediate product of smelting iron ore with coke and limestone in a blast furnace. Pig iron has a very high carbon content, typically 45%, which makes it very brittle and not very useful directly as a material. A Selection of Mechanical Properties (from Gordon (1979)) Wrought iron

Steelmaking is the process of producing steel from iron ore and/or steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

•Both the slag and iron are drained from the bottom of the furnace. •The slag is mainly used to build roads. •The iron whilst molten is poured into moulds and left to solidify this is called cast iron and is used to make railings and storage tanks. •The rest of the iron is used to make steel. 10.

Steel making is the method of processing and producing steel from iron ore and scrap. It focuses on removing the slugs and other unwanted materials like phosphorus, sulphur, silicon, nitrogen, and excess carbon from the raw iron. The next step targets on alloying it by adding various elements like manganese, chromium, nickel, and vanadium. Needless to say, different grades of steel
