Results showed that the peak value of NO concentration, total of NO emission, and fuel-N ...

Blast furnace - Wikipedia

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...

Conversion of Mill Scale Waste into Valuable Products via ...

Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a ...

Steel making process – ArcelorMittal

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 content varies.

Iron and Steel Manufacturing

Iron and Steel Manufacturing Industry Description and Practices Steel is manufactured by the chemical reduction of iron ore, using an integrated steel manufac-turing process or a direct reduction process. In the conventional integrated steel manufacturing process, the iron from the blast furnace is con-verted to steel in a basic oxygen furnace ...
