1A Manufacturing Process for Iron and Steel
The direct reduced iron is produced by reducing iron ore with reformed natural gas, whose principal components are hydrogen, carbon monoxide, and methane. The scrap, along with direct reduced iron, is then melted in an electric arc furnace (denoted EAF hereinafter) to produce molten steel which is subsequently processed by the continuous ...
Direct Reduction Plant Products || KOBE STEEL, LTD
Direct Reduction is an iron making process for the new era, which utilizes natural gas to reduce iron ore to produce Direct Reduced Iron (DRI). As Direct Reduction Plants are not built on the same, enormous scale as Blast Furnaces, their investment costs are lower, and they have been mainly constructed in developing countries where natural gas ...

The HBI direct reduction process - voestalpine
Nov 03, 2016 · The direct reduction process. HBI is the product of reducing iron ore with natural gas. This is called the direct reduction process and is an environmentally-friendly production process; a DRI plant uses natural gas which is more environmentally sound than coke. The reduction process takes place in the reduction tower.
Fire in Direct Reduced Iron Fines - bulk-online.com
Jun 11, 2014 · Dear All, We have a Midrex Sponge Iron plant producing cold DRI. Since some days we are noticing fire in DRI dust. The temperature stays normal at the furnace discharge but when the product gets transferred after moving through a belt for around 200 meters to another belt the DRI dust catches fire. It is happening again and again. We have started using some new pellets since some days but …
MIDREX® — THE LEADING DRI PRODUCTION PROCESS
Midrex is an innovative ironmaking process, developed for the production of direct-reduced iron (DRI) from iron ores and primarily natural gas. Midrex is a gas-based shaft furnace process that converts iron oxides – in the form of pellets or lump ore – into direct reduced iron (DRI).
Iron (Fe) Nutrition of Plants
Iron uptake by the plant is not as simple as with other essential elements. Iron is taken up by plant roots in greatest amounts in the zone of the root between cell elongation and maturation, about 1 to 4 cm behind the root tip. Uptake of Fe by the plant is an active process, that is, energy is expended by the plant to take in Fe. Iron uptake
Direct Reduced Iron (DRI) | International Iron Metallics
Direct Reduced Iron (DRI) is the product of the direct reduction of iron ore in the solid state by carbon monoxide and hydrogen derived from natural gas or coal. See more information about the production of DRI.Most gas-based direct reduction plants are part of integrated steel mini-mills, located adjacent to the electric arc furnace (EAF) steel plant. DRI can be either hot or cold charged to the EAF. Some steel companies ship DRI from their captive direct reduction plants to their remote ste...
COREX & FINEX - NEW DEVELOPMENTS IN UTILIZATION OF
The product delivered to the smelting reduction vessel is quite similar to the reduced iron that is produced in direct reduction technology, namely direct reduced iron (DRI). More coal is needed in the smelting reduction vessel to melt the iron. Processes operating at such a high level of pre-reduction are referred to as first generation processes.
