Overview of the difference between pellets and sponge iron
Sponge iron and iron pellets are two popular raw materials used in production. Sponge iron, also known as reduced iron, is produced by reducing iron ore into pellets using non-coking coal in a rotary kiln.
Iron pellets, on the other hand, are produced by melting iron ore, coke (made from coal), and limestone in a blast furnace. The resulting liquid iron is then poured into a mold to form iron pellets.
?What is the difference between pellet and sponge iron
The main difference between sponge iron and iron pellets lies in their production process, composition, and properties. Sponge iron is a purer form of iron with a lower carbon content compared to pig iron. It has a higher melting point, is more resistant to oxidation, and is more malleable and ductile. On the other hand, iron pellets are more brittle, have a higher carbon content, and are less pure. Another difference between pellets and sponge iron is their cost. Sponge iron is cheaper to produce because it does not require coke, which is an expensive raw material used in the iron pellet production process. However, iron pellets have a lower melting point, which makes it easier to cast and shape into various shapes.

Uses of iron pellets
Iron ore has been an essential raw material in the manufacturing industry for centuries. Its versatility and strength have made it a popular choice for a wide range of applications. Iron ore is used in the production of steel, iron castings, pipes and wrought iron. It is also used as a raw material in the production of wrought iron and wrought steel, which is used in ornamental ironwork, railings and gates. One of the most common uses is in the production of cast iron, which is used in a variety of applications such as cookware, pipes and engine blocks. Iron ore is also used in the production of steel, which is used in construction, transportation and many other industries.
Properties of iron pellets
Iron ore is an alloy of iron, carbon, and other elements produced by smelting iron ore in a blast furnace. The properties of iron ore can vary depending on the specific composition and manufacturing process used. Here are some of the physical and chemical properties.
Physical Properties:
Boiling point: 2927 °C
Density: 6.9 - 7.8 g/cm3
Color: Dark gray to black
Melting point: 1150 - 1250 °C
:Chemical properties
Carbon content: 2.5 - 4%
Silicon content: 0.5 - 3.5%
Sulfur content: 0.05 - 0.15%
Manganese content: 0.1 - 2.5%
Phosphorus content: 0.1 - 2.0%
Iron pellet ingredients
Pig iron is a high-carbon ferrous material produced during the smelting of iron ore with coke and limestone. The composition of pig iron varies depending on the raw materials used and the smelting conditions, usually containing 3.5 to 4.5 percent carbon along with various other elements.
In addition to carbon, pig iron contains other elements such as silicon, sulfur, phosphorus, manganese and small amounts of other elements.
Silicon is usually present in concentrations between 1 and 3 percent, while sulfur and phosphorus are present in concentrations of 0.1 percent.
Manganese is usually present in concentrations up to 1 percent, and small amounts of other elements such as copper, nickel and chromium may also be present.
The process of producing iron pellets can be divided into four main stages:
Preparation of raw materials: This stage involves the extraction of iron ore and the preparation of other raw materials including coke and limestone.
Charging: The prepared raw material enters the blast furnace, which is then sealed and heated.
Reduction: The heat causes a chemical reaction, resulting in the iron ore being converted into molten iron.
Casting: The molten pig iron is then discharged from the bottom of the furnace and poured into pigs.

Uses of sponge iron
It contains manganese, sulfur, and phosphorus. The carbon content of sponge iron can vary depending on the reducing gas used and the reduction temperature. In general, sponge iron produced with natural gas has a higher carbon content than sponge iron produced with coal gas.
It is a very versatile product that has a wide range of applications in several industries. Some of the most common uses of sponge iron include:
Steelmaking: Sponge iron is commonly used in steelmaking as a substitute for scrap metal. It has a high iron content and low levels of impurities, making it an ideal raw material for steel production.
Foundry industry: Sponge iron is used in foundries to produce high-quality cast iron products.
Chemical industry: Sponge iron is used as a catalyst in the chemical industry to produce chemicals such as ammonia, methanol, and hydrogen.
Electric arc furnace: Sponge iron can be used as a coolant and energy source in electric arc furnace steelmaking.
Types of sponge iron
Sponge iron is a form of direct reduced iron produced by reducing iron ore in the form of lumps, pellets or granules using a reducing gas such as hydrogen, natural gas or coal.
