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. The DRI assumed nick name Sponge Iron due to its appearance of sponge under microscope. The technology is available indigenously.

We have followed the Quality Assurance Plan (QAP) by the qualified technical team. Our qualified chemical engineer visited to user end to provide technical support to solve technical/ operational problem faced by our valuable customer.

The rotary kiln DRI process when accepted non-coking coal as major Material and source at reduction of iron oxide, the process found most economically viable.
It is observed that characteristic of raw materials, design of reactor need careful operational parameters to achieve productivity.
The sponge iron retains the size as that of iron ore (5-18 mm).
The sponge iron contains little oxygen as Fe is less than 11%.
It picks up little carbon during process (0.0009-0.15).
