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

Iron and Steel Industry: Process, Loion and …

The time consumed in the steel making process is far less than all the previous methods. For the global energy crisis in the 70’s and to reduce the processing period, continuous casting method was introduced. In this integrated manufacturing process, in a single continuous process pig iron is converted to steel. Loion of Iron and Steel

New Technologies for Steel Manufacturing Based upon Plant

Oxygen is blown into molten iron charged in a BOF by a water-cooled lance inserted in the furnace from above. The carbon component in the molten iron burns with the oxygen, and the molten iron becomes steel. During this process, the molten iron is vigorously agitated and the splashed metal deposits on the upper part of the furnace wall as scale.
