Direct Reduced Iron, 

manufactured by directly oxidizing or reducing iron ore using reducing gas or carbon, commonly known as sponge iron. There are several ores that may be recovered directly.

When iron oxides are converted to metallic iron by direct reduction, temperatures below the metal’s melting point are used. These methods, which include heating iron ore in a furnace to temperatures exceeding 800 to 1200 degrees Celsius while reducing agent synthesis gas, a combination of hydrogen and carbon monoxide, are how reduced iron gets its name.

The name “sponge iron” refers to the material’s appearance as porous, spherical chunks that have a spongy look.

Because there is less iron waste, iron is more expensive, and there are environmental issues, sponge iron, which has a high quality of iron, is increasingly popular now.

Sponge iron contains between 84 and 95 percent iron by grade.

Sponge iron is an excellent resource for producing iron and steel because of its high quality.
