spong iron is the porous product of direct reduction of iron ore .it is better than scrap of iron because of less polution of the environment and more homogenous and have less harmfull element such as phosphor sulphur( S and P).

How sponge iron produced and the use of sponge iron?

Sometimes known as direct-reduced iron, sponge iron is a product that is produced using iron ore. The iron ore is often in the form of pellets or lumps, and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source. Sponge iron can be produced in several different types of furnaces, including coke or charcoal ovens, blast furnaces, and basic oxygen furnaces. There are several benefits associated with sponge iron that allow it to compete effectively with other types of smelted irons. One has to do with the actual composition of the final product itself. For example, this type of iron is considered richer than pig iron, another type of iron commonly produced in blast furnaces. Direct-reduced iron has a slightly higher iron content, which often makes it better suited for use in electric furnaces. In addition, the gases emitted during the production of sponge iron can be harvested and used in various other applications. This by-product of the iron making process helps to offset the cost of producing the iron, as well as aid in keeping other processes that require the gas for proper production. Sponge iron can also be used to produce a powdered ore that works very well when mixed with other metals in the production of different types of iron-based products. One of the more common uses for sponge iron is the creation of wrought iron. Iron of this type is helpful in the creation of ornamental objects for use around the house, such as decorative grills for screen doors, burglar bars for windows, and even for various types of wall hangings. Sponge iron is also often used for the manufacture of components used to create durable lawn and patio furniture. When properly treated, wrought iron furniture can easily resist deterioration from the weather, and last for a number of years. In recent years, refinements to the production of sponge iron have made it possible to reduce the iron without necessarily having to melt the ore. Because the iron can be made into pellets and even into powder, it is an economic and useful substitute for the scrap metal sometimes used by steel manufacturers. The amount of time and resources required to produce sponge iron is minimal, so it is possible to manufacture large amounts quickly, a fact that only adds to the advantages of this type of iron product.

Why iron and steel industry is called the backbone of moden economy?

Steel and iron are known as the backbone of modern industry because:1. Almost everything is made of steel or iron, or has been made with tools and machinery off these metal.2. Ships, trains, trucks and autos are made largely of steel or iron. Even the safety pin are made from steel or iron.3. Minerals are mined with steel or iron equipments.4. Large buildings have steel or iron framework.5. Oil wells are drilled with steel or iron machinery.


What Are The Ingredients In iron?

Iron is an element, so the only ingredient in pure iron is iron. Iron as used in inductry typically is combined with small amounts of carbon, tungsten, cobalt and other elements to create steel and types of 'iron.' Well iron is made of tons of stuff that is just a few thing you can go to www.myminerals.com to find out alot more!!!!!!!!

Is propane used as feedstock for sponge iron?

No, propane is not typically used as a feedstock for producing sponge iron. The most commonly used feedstock for sponge iron production is natural gas or coal. These feedstocks provide the necessary carbon and heat required for the direct reduction process to convert iron ore into sponge iron.


Can sponge iron making is a primary metallurgical process - yes or no?

Yes. Sponge iron making is a primary metallurgical process where iron ore is directly reduced in the solid state to produce sponge iron, which is a highly porous form of iron used in steelmaking.


Difference between pig iron and sponge iron?

http://encarta.msn.com/encyclopedia_761559225/iron_and_steel_manufacture.html Provides the answer. basic summary: 1. Pig Iron and Sponge Iron are the result of different production processes 2. Which results in different purities. Pig Iron has a lower purity than Sponge Iron.


What is the difference between Sponge iron and pig iron and their application?

Sponge iron is produced by reducing iron ore pellets in a direct-reduction process, whereas pig iron is produced by melting iron ore with a high-carbon fuel in a blast furnace. Sponge iron is mainly used as a raw material for steelmaking in electric arc furnaces, whereas pig iron is typically used in the production of cast iron and wrought iron products.

How do you calculate the yield of production of sponge iron?

The yield of production of sponge iron is calculated by dividing the weight of sponge iron produced by the total weight of iron ore initially taken for the process, and then multiplying by 100 to get the percentage yield. It is important to consider losses during the process to get an accurate yield calculation.
