1A Manufacturing Process for Iron and Steel

The MIDREX process produces direct reduced iron (hereinafter referred to as DRI ). The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed.

OVERVIEW OF THE STEELMAKING PROCESS

Steelmaking Overview. Steelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium, and vanadium are added to produce the exact steel required.

Direct Reduction Process (MIDREX) | Middle East Steel Industry

Steel made in an EAF uses electricity to melt steel scrap. Depending on the plant configuration and availability of steel scrap, other sources of metallic iron such as direct-reduced iron (DRI) or hot metal can also be used. Additives are used to adjust the steel to the desired chemical composition. Electrical energy can be supplemented with oxygen

DESIGN, FABRICATION AND ERECTION OF STEEL …

Jun 21, 2018· Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

Forms of DRI

While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material. As the predominant production method in Europe is the conventional, coal-dependent BF/BOF process, the need to assess alternative breakthrough technologies to reduce carbon ...

Nucor Corporation, the largest steel company in the United States, was looking for a way to increase its competitive advantage in the industry. One way was to invest in a direct iron ore reduction facility. This process involves converting natural gas and iron ore pellets into high-quality DRI (direct-reduced iron),

Steel Production

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
