For this study, partially reduced briquettes made from iron minerals were collected from an industry in the vicinity of Rourkela, Odisha, India. Briquettes upon solid state reduction at 1250°C are partially melted which hinders further reduction at higher temperatures.
Read MoreProcess of Steel-making from Iron Ore. Steel is an alloy consisting mainly of iron, carbon and other elements. According to its carbon content, iron can be divided into pig iron and wrought iron. Pig iron contains between 2.11 and 4.5 percent carbon, wrought iron less than 0.0218 percent and steel between (0.0218 and 2.11 percent).
Read MoreC + O2 → CO2. The heat produced by this reaction is the main source of heat in the blast furnace that is used for iron production. At the bottom of the furnace, the temperature is very high, which causes more of the coke to react with carbon dioxide, producing carbon monoxide. C + CO2 → 2CO. The carbon monoxide then becomes the “reducing ...
