What is sponge iron and its advantages?

What is sponge iron and its advantages?

Sponge Iron is a substitute for steel scrap for the manufacturing of steel through the EAF/IF courses. Sponge Iron acts as a superior feedstock for the electric furnaces used by various factories which allow the factories to use lower grades of scrap or to create higher grades of steel.

Which is better sponge iron or pig iron?

Sponge iron is superior to pig iron as it is richer in iron content. Because of this property, it has many uses in electric furnaces. We can mix sponge iron, in its powdered form with many other metals to manufacture a variety of iron-containing products. For instance, we can produce wrought iron from sponge iron.

What is the use of sponge iron?

Sponge iron is used in the iron and steel industry as a substitute for scrap in induction and electrical arc furnaces. Over the years, the shortage of expensive melting scrap has made sponge iron a significant raw material for manufacturing high quality steel.

What is the difference between sponge iron and DRI?

Steel is produced from iron ore or scrap. Iron ore is a mineral aggregate that can be converted economically into iron. Sponge is an intermediate product, which is produced from iron ore by means of direct reduction (= DRI or directly reduced iron) and that is then further reduced and smelted in an electric furnace.

Which is the purest form of iron?

Wrought iron
Wrought iron is the purest form of iron. It contains 0.12 to 0.25% carbon and is thus the purest form of iron.

Why is it called sponge iron?

WHY IS IT CALLED SPONGE IRON? Iron oxide ores taken out from the Earth are allowed to absorb carbon by a reduction process. In this natural reduction, as the iron ore is warmed up with carbon, it results in a surface with hole marks, hence the name “Sponge Iron”.

How many types of sponge iron are there?

Four sponge iron (SI1, SI2, SI3, and SI4) plants with different installed capacity and sponge iron (SI) production have been considered for studies based on the baseline methodology.

What is sponge iron powder?

the sponge iron. Main material in powder metallurgy industry that consumes 60-80% of iron powder. Especially in magnetic materials. Welding Iron powder in the coating of welding electrode can significantly improve deposition efficiency.

Why is sponge iron used in specialty steel?

The level of metallization (expulsion of oxygen) shows the quality of sponge iron. It is the proportion of metallic iron to the total iron present in the product. Thus, this makes for the efficient energy feedstock for specialty steel producers, which used to depend upon scrap metal.

What are the advantages of SIPL sponge iron?

Advantages of SIPL Sponge Iron / DRI: High Fe Content and high degree of metallization. Uniform and Consistent quality. Lower Sulphur & Phosphorus content. Negligible tramp elements. Minimum dust generation during handling. Good flow ability in bins and conveyors for continuous and trouble free charging.

Can a sponge iron be used in an electric furnace?

The DRI procedure can utilize poor quality coal that is inadmissible for ordinary iron making. ➢ A sponge iron has indistinguishable iron content from the pig iron; therefore it is an excellent feedstock for the electric furnaces utilized by smaller factories.

How does the iron sponge process affect sweetening?

In addition, pressure has relatively little effect on the adsorptive capacity of a sweetening agent. The use of iron sponge process for sweetening sour gas is based on adsorption of the acid gases on the surface of the solid sweetening agent.
