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 4-5%, which makes it very brittle and not very useful directly as a material.

Iron and Steel HIGHLIGHTS PROCESSES AND TECHNOLOGY STATUS – The basic materials for iron production are iron ore, coal and coke (also used as energy input to the process) or alternative reducing agents, limestone and dolomite. Steel production requires iron, steel scrap and lime (burnt limestone).
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 (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.
Production of pig iron in a blast furnace 6 Even though there is evidence of iron production in crucibles already in ancient times, reduction of lump ores by charcoal was used for its practical use at the beginning of iron industry. Charcoal provided necessary heat and reducing gas. Reached temperature did not exceed 1000 °C.
As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly 'topped up'.
Apr 19, 2012· Anintermediate product of puddling is known as refined pig iron, finersmetal, or refined iron. Pig iron can also be used to produce gray iron. This is achieved byremelting pig iron, often along with substantial quantities of steel andscrap iron, removing undesirable contaminants, adding alloys, andadjusting the carbon content.
Technical Support Document for the Iron and Steel Sector: Proposed Rule for Mandatory Reporting of Greenhouse Gases . INTRODUCTION . The iron and steel industry in the United States is the third largest in the world (after China and Japan), accounting for about 8 percent of the world's raw iron and steel production . 1
Iron (Fe), derives it name from the Latin word ferrum. In its pure form iron is lustrous, silvery, soft, and ductile. However, pure iron is a poor engineering material, generally not as strong as most plastics. Cast irons are based on the Fe-C system, and the solid-state transformations on which cast iron heat treatments are based are
