Direct Reduced Iron. Direct reduced iron (DRI) is the alternative iron source for steelmaking. Its advantages as a iron product and diluent for impurities, introduced with scrap, are well documented. DRI is also known as sponge iron. It refers to porous iron produced by the direct reduction (DR) process.
Storage and Transportation: The sponge iron is then stored or transported to steelmaking facilities where it is used as a raw material in electric arc furnaces (EAFs) or induction furnaces. Applications of Sponge Iron Sponge iron plays a crucial role in the steelmaking process and is used in various applications:

Freshly prepared sponge iron is highly prone to oxidation whenever it encounters air. The heat generated in the oxidation reaction increases the susceptibility of oxidation, thereby starting a sort of chain reaction and ultimately leading to the fire of sponge iron. Hence, storage and handling of sponge iron are major concerns of the … بیشتر

Description / Application / Shipment - Storage / Risk factors. 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.
The document provides guidelines for pollution prevention and control for sponge iron plants. Key points include: 1) Plants below 100 TPD capacity are not economically viable to install pollution controls and should be phased out. Larger plants must install adequate pollution controls like ESP to meet emission standards. 2) Solid wastes like char should be reused for power generation in ...
