Now, when talking about sponge iron, the context of the steel industry comes. The steel industry, as we know, has been one of the major driving forces for the modern-day world’s development. Steel is the most favoured material for manufacturing, transportation, construction, consumer products etc. It is a multi-functional and very flexible material, and it steadily supports the economies of many countries in the world.


And when it comes to manufacturing high-quality steel products, the shortage of expensive melting scrap has propelled the use of sponge iron, making the latter an essential raw material for manufacturing steel. In this article, we will briefly talk about sponge iron, covering its definition, uses, and benefits throughout the following part.


What is Sponge iron, and what are its uses?


Sponge iron, in simple terms, refers to a metallic product manufactured using the direct reduction of iron ore in the solid-state. It is a standby for scrap - primarily used in steelmaking through the secondary route. In other words, it is used in the iron and steel industry as an alternative to scrap in induction and electrical furnaces. Another name for sponge iron is direct reduced iron or DRI.


To make Sponge helpful iron, as in to use for commercial purposes, the Sponge has to be removed from the furnace, then repeatedly beaten using hammers, eventually removing slag, oxidising carbon etc. Sponge iron has a low sulfur substitute and a high degree of metallisation. It is available in uniform and consistent quality.


Regarding the uses of sponge iron, it has notable applications. It is an important material for producing TMT bars, DI pipes etc. It also works as a core feed material for steel plants. Remarkably, the waste gases generated from sponge iron production can be used to generate power in a plant, thereby effectively tackling wastes.


The above is a fundamental analysis of sponge iron and its varied uses. The material is precious and has been in use for essential purposes.
