ABE offers Sponge Iron Plants of capacity ranging from 100 to 300 TPD
INTRODUCTION
Direct-reduced iron (DRI), also called sponge iron,[1] 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. This process of directly reducing the iron ore in solid form by reducing gases is called direct reduction.
MANUFACTURING PROCESS:
Sponge iron can be produced in several different types of furnaces, including coke or charcoal ovens, blast furnaces, and basic oxygen furnaces. Direct reduction, an alternative route of iron making, has been developed to overcome some of these difficulties of conventional blast furnaces. DRI is successfully manufactured in various parts of the world through either natural gas or coal-based technology. Iron ore is reduced in solid state at 800 to 1,050 °C (1,472 to 1,922 °F) either by reducing gas (H2+CO) or coal. The specific investment and operating costs of direct reduction plants are low compared to integrated steel plants and are more suitable for many developing countries where supplies of coking coal are limited.
