Direct reduced iron (DRI), also called sponge iron, [1] is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas which contains elemental carbon (produced from natural gas or coal) and/or hydrogen. When hydrogen is used as the reducing gas no carbon dioxide is produced.

2024年9月13日 · Sponge iron, also known as direct reduced iron (DRI), is a highly versatile and essential material in the steel industry. It is characterized by its porous structure, which resembles a sponge, hence the name.

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200°C.

2024年3月11日 · Direct-reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore by a reducing gas produced from natural gas or coal.

2023年10月10日 · Let’s delve more into understanding one of the crucial by-products of Iron – Sponge Iron. Sponge Iron gets its name from its unique physical characteristics. It has hole marks on its surface. These hole marks emerge during the ‘natural reduction’ process where iron ore is warmed with carbon.

one in near term to reduce the energy consumption from the steel sector. This holds true not just for integrated steel plants but also in the highly disaggregated sponge iron sector, which is dominat.

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.

This article delves into the essence of sponge iron, its production process, applications, benefits, and the impact it has on the global steel market. Sponge iron, also known as direct reduced iron (DRI), is a product of the direct reduction of iron ore.
