So sponge Iron is a replacement of scrap which can be produced at considerably low price with high production rate & less consumption. With the use of sponge Iron in Arc furnaces, a steel of balanced carbon & negligible presence of undesirable elements can be produced. As a result it helps the steel makers to produce any type of special steel.
