Direct Reduced Iron (DRI) Production Plant The use of DRI ...

A direct reduced iron (DRI) production plant is a shaft reduction furnace to produce DRI with large metal iron content by directly reducing iron ore (or iron ore pellets) with reducing gases. While the produced DRI is mainly used as the raw material of electric steelmaking, it is also used as

Resources Trend and Use of Direct Reduced Iron in ...

Direct reduction is a process for reducing iron ore in the solid state. It requires much less capital investment than the BF process and requires no coke. Therefore, DR plants have nbeen built mainly in oil and natural gas producing countries to supply raw iron for EAF processes. Particularly in the

The HBI direct reduction process - voestalpine

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.

Direct Reduced Iron (DRI) - QITAPANDI

Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent.

Direct reduced iron - Wikipedia

The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles. The direct reduction process can use natural gas contaminated with inert gases, avoiding the need to remove these gases for other use.

Direct Reduction Iron Technology (DRI) Heaters ...

The process of reducing gas to convert iron ore into metallic iron is known as direct reduction. Direct Reduced Iron (DRI) is a manufactured metallic material produced by the reduction (removal of oxygen) of iron oxide at temperatures below the melting point of iron (1536° C or 2797° F).
