Sep,sponge iron is also known as direct reduced iron using highquality ore, using the principle of an oxidationreduction reaction, in a rotary kiln, shaft kiln, or other reactors, the iron ore undergoes a reduction reaction and becomes porous sponge iron sponge iron has a low content of harmful impurities such as sulfur and

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and …

Index Terms—Sponge iron process, rotary kiln, temperature profile, artificial neural network. I. INTRODUCTION Sponge iron is the metallic form of iron produced from reduction of iron oxide below the fusion temperature of iron ore (1535oC) by utilizing hydrocarbon gases or carbonaceous fuels as coal. The reduced iron having high

Production technology of sponge iron. The production of sponge iron is made by rolling iron oxide sheet, roasting at high temperature in tunnel kiln or rotary kiln, and reducing iron oxide by pulverized coal. The metal conversion rate has an important effect on the quality and production cost of the final reduced iron powder.

Sponge iron being magnetic gets attracted and gets separated from non- magnetic char. The iron ore and coal crushed and screened to respective sizes are fed to rotary kiln through feed tube in pre-determined ratio. The rotary kiln is slightly inclined at an angle 2.5 deg and rotated by

The reduction is carried out in a rotary kiln (which is inclined and rotates at a predetermined range of speeds) at a stipulated temperature (8500C – 10500C). The inclination and the rotary motion of the kiln ensure that the raw materials move from the feed end to the discharge end of the kiln and during this movement the actual reduction of iron ore to iron takes place.

Sponge iron is a metallic product produced through direct reduction of iron ore in the solid state It is a substitute for scrap and is mainly used in making steel through the secondary route SL/RN technology is a coal based rotary kiln direct reduction process The sponge iron kilns give off hot gases rich in carbon di-oxide WSL has...
