Sponge iron

Sponge Iron / Direct Reduced Iron (DRI) is so named because iron ore reduced to metallic iron without melting first. It is basically a manufactured high ferrous content change material for iron and steel making. It is produced in lump or pellet form, compacted and briquette form known as hat Briquette Iron (HBI). It is the main substitute for steel form known as Hat Briquette Iron (HBI). It is the main substitute for steel scrap in steel making. Sponge iron production requires small quantity of energy, as no melting process is involved.
