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.
What qty of iron ore and coal be used in the production for getting 1 metric ton of sponge iron?
coal throw pipe adjustments
What is a mini steel plant?
Mini steel plants are smaller, have electric furnaces, use steel scrap and sponge iron. They have re-rollers that use steel ingots as well. They produce mild and alloy steel of given specifications.
Why do made sponge iron?
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).
What is primary ore of iron used to produce iron from steel for automobiles tools and bridges?
hemalite
Can sponge iron making is a primary metallurgical process - yes or no?
Yes, sponge iron making is a primary or can be a primar metallurgical process base on the Chemistry information that is provided.
Why sponge iron catch fire when it contect with water?
Sponge iron contains carbon oxygen iron sulphur phosphorus when water is mixed it form reaction between oxygen and hydrogen it produce enomous heat that its starting to burn --
When you heat iron oxide powder with magnesium powder?
When you heat iron oxide powder with magnesium powder, a chemical reaction takes place where the magnesium reacts with the oxygen in the iron oxide to produce iron metal and magnesium oxide. This is a type of redox reaction where reduction and oxidation occur simultaneously.
What happens to iron powder and salt mixture when it is added to water?
When iron powder and salt are added to water, the iron powder will react with the water to produce iron oxide (rust), hydrogen gas, and heat. The salt will dissolve in the water. This reaction is a chemical change, resulting in a mixture of iron oxide, hydrogen gas, salt solution, and any unreacted iron powder.
How do you found Fe total of sponge iron?
Measuring the mass of sponge iron.
How do you do copper coating on iron powder?
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
What is the relation between metallic iron and total iron in sponge iron?
Metallic iron refers specifically to the iron that is in its metallic form in sponge iron. Total iron in sponge iron includes metallic iron as well as any iron present in other forms such as iron oxides. Therefore, metallic iron is a subset of total iron in sponge iron.
How Fe separation from coal base sponge iron?
First sponge iron must be Roll crusher Next Magnet separation Next Create block sponge iron
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.
What happens to iron filings and sulfur powder when heated?
When iron filings and sulfur powder are heated together, they undergo a chemical reaction to form iron sulfide. The iron sulfide produced is a compound that has different physical and chemical properties compared to iron or sulfur alone.
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.
Why is iron powder magnetic?
Iron is magnetic but copper isn't. So I guess iron powder is magnetic while copper powder isn't.:)
