the price of sponge iron is calculated per ton around the world. today many countries are looking after sponge iron because it is the first material used in the production of steel and byproducts of steel in the market. Sponge iron is one of the materials called directly reduced iron. Its rock is regenerated in the solid state with some gas between 800 and 1050 degrees Celsius, while iron is rarely found naturally in nature and in the form of oxides, so iron is considered rock in nature. About 5% of the world’s steel is made from sponge iron, and this is increasing. Today, sponge iron is made by reducing iron ore without smelting it, making it an energy-efficient resource for specialty steelmakers who rely on scrap metal. sponge iron can be used to produce a variety of products such as iron beams, corners, boards, and various types of pipes. The history of sponge iron production can be traced back to 2000 and started in the Middle East. In those years, due to the lack of scrap iron, although the quality of scrap iron was declining, no one was willing to use sponges because everyone thought that sponge iron was not suitable for induction ovens. To produce sponge iron, iron ore is recovered without smelting, as well as pig iron is produced from these furnaces. Sponge iron contains approximately 30% to 70% pure iron and is used to make steel. Benefits of sponge iron
- It is a better substitute for scrap in steel making plants.
- A large amount of iron improves the quality of its metalworking
- less sulfur and phosphorus
- It has the waste element present in scrap iron and not present in the sponge.
- This material can be used as a coolant.
Briquettes are a compressed form of sponge iron designed and produced for easy transport. Briquettes are the best way to greatly reduce the percentage of rust, while briquettes reduce porosity and increase density and wear resistance. Sponge iron is a widely used material in the steel and crude steel production industry, and its unique properties make it a suitable replacement for scrap in the steel production industry. Different types of briquettes can be mentioned, e.g. hot sponge iron briquettes, soft sponge iron briquettes, and cold sponge iron briquettes.
sponge iron per ton
the production and manufacturing of sponge iron is per ton because during the first stages of production, they use materials per ton to start the procedure. Iron is one of the most widespread and consumed metals in the world. There are few structures or factories in the world that do not use ferrous metal or its derivatives. The final product made from iron must go through many stages because first the iron ore must be converted into iron and then by combining different types of iron with different alloys, different chemical compositions, different strengths, and resistance levels. ST37 rebar is one of the steel alloy products. There is an iron ore product called sponge iron that replaces iron scrap and is used to make steel products. The direct removal of oxygen from iron ore results in sponge iron, also known as porous pellets. The process of producing sponge iron occurs during the direct reduction of iron without smelting iron ore. Sponge iron products are spherical and porous in appearance, so they are called sponges. After melting, during the casting process, the sponge iron is transformed into three products, ingots, plates, and rods, which are sent to the factory for various purposes, where they are transformed into other more widespread products. The iron content of pellets is very high and can be a good substitute for scrap iron. The extraordinary thing about pellets is that it refers to iron sponge and it is on par with it. Iron ore is generally regenerated by two methods, natural gas, and coal, resulting in sponge iron. The process of activating iron ore with natural gas is carried out by three methods: Midrex, HYL, and Purofer, of the three methods Midrex is the most widely used. In addition, the process of recovery of iron ore and production of sponge iron from coal is done through Jindal DRC and SL/RN methods.

the price of sponge iron and products related to this good is calculated per ton and there are many different methods in manufacturing and producing HBI. HYL method: In this method, natural gas is also used to recover iron ore, except that the equipment and production steps required for the final product are slightly more complex and expensive than the Midrex method. The iron ore recovery process generally consists of two parts: the natural gas production and decomposition part and the iron reduction furnace part. In the natural gas production unit, methane natural gas is combined with water vapor and broken down into its components. These elements are then blasted together with iron ore in a furnace and the resulting product is sponge iron. The sponge iron produced by this process contains more carbon, which is the so-called carburizing treatment. Production of the iron sponge by SL/RN method This method is another iron ore recovery method that uses coal instead of natural gas for the process. The process includes a feed portion of a combination of raw materials. The raw materials include iron ore or iron lumps, which are first introduced into the feed section, then lime and dolomite are added to these materials along with coal and then sent to the horizontal furnace for the regeneration stage. The reason for using dolomite and lime in the raw materials is to help maintain the required sulfur percentage for the process. In the horizontal kiln section with a slight incline and moving in a rotary manner, the raw material is poured there and moves very slowly in the rotary kiln. In this phase, the temperature of the furnace rises until the coking coal begins to burn and produce carbon dioxide. Carbon dioxide continues to be produced and the temperature rises until the iron ore is fully regenerated. The regenerated iron ore is then sent to a cooling unit where the sponge iron is magnetically separated as the final product.
During the last 15 years, the price of iron and byproducts of iron have experienced a big fluctuation and this has affected many industries. Due to the existence of these various factors that affect the price of iron, the price of rebar is not even predictable. The increase or decrease in demand, political factors, and the increase in currency prices are obvious factors that affect the price of iron. One of the important products in the market is rebar. As you know, rebar and other sections never have a fixed price. One of the effective options for lowering and increasing iron prices is the demand from buyers and consumers. Prices have also changed as the cold season begins and demand slows. Since the fall and winter season is not the best time to implement civil and construction projects, most contractors keep the project implementation inactive or semi-active until the appropriate time for concrete and restoration. Everyone knows that this season is inauspicious, and according to previous years’ experience, the price of sectional steel faces a decline during this period this year. It can therefore be said that mill offers have also fallen due to reduced rebar purchases and consumption in recent months. Undoubtedly, rebar is one of the most important materials today. This valuable steel is the main foundation of today’s construction, without which it would be impossible to promote construction in its form today. Reinforcement standards are undoubtedly one of the important factors for designers of large and small structures. The mechanical properties of this product vary according to its manufacturing standards, which makes it possible to use it differently in different parts. In summary, it can be concluded that the lack of suitable construction conditions due to seasonal changes and prevailing weather conditions is one of the main reasons for the fall in iron prices, followed by the fall in iron prices. Rebar prices have increased due to seasonal changes and reduced demand. The current interest rate reduction process is expected to continue.
- iron price per ton
The amount of iron mixed with alloyed iron has a specific effect on the physical properties of the steel due to its special effect on the microscopic crystal structure, and the price of these products is also calculated in tons. These effects show up well in various heat treatments to improve the steel’s physical properties.
- pure iron (soft)
The cast iron has a carbon content of 0.02% and is conventionally obtained by melting the cast iron in a rotating retort furnace. Theoretically, this work continues until all the carbon in the pig iron burns to obtain a mushy soft iron, which is then removed from the furnace and hammered. The melting temperature of soft iron is very high, around 1540 degrees Celsius. Previously, it was used for tools and parts that had to be under tension. This iron is flexible and highly functional, easy to press at red temperatures, and therefore has higher corrosion resistance than expected.
This iron has a carbon content of about 2% and is produced by the carbonizing pig and scrap iron in a furnace with coke. Its low melting point makes it suitable for casting. However, unlike soft iron, it cannot be processed in the molten state and is a brittle material. Its corrosion resistance makes this product suitable for the manufacture of steam boilers and outdoor furniture as well as for directing rainwater (gutters). Different types of cast iron depend on their different crystal structures. The gray cast iron mainly used has fine graphite crystals which make it brittle and give a gray color in sections. The carbon in white cast iron is in the form of cementite crystals, formed by rapid cooling of the melt. This material can be softened to reduce its brittleness. Another type of pig iron that is flexible is malleable cast iron, which is made by adding magnesium and iron silicate, and another type of pig iron that crystallizes carbon and turns it into graphite balls. This material has high tensile strength and high impact and compression resistance. Iron products used on the street, such as sewer valves and sewer valves for electric and telephone cables, are made from recycled gray cast iron, which is heavy but fragile. Where greater impact resistance is required, such as public roads, lighter, more flexible iron parts are used. Rainwater drainage products cast by the casting method (sand) are usually made of gray cast iron, while sewer systems are made of gray cast iron, which is malleable.

Today, there are many iron products, primarily steel, and many problems affect the price. A wide variety of steels are available on the market, exhibiting the unique properties of each steel, depending on the percentage of carbon, heat treatment, and alloying material additions. The carbon content in steel typically fluctuates between 0.07% and 1.7%, alone producing a wide range of physical properties. Mild and malleable steels are generally soft and many operations can be performed on them in cold conditions. Usually, heat-treated medium carbon steel. They are high carbon hard steels and form steels that exhibit greater resistance to damage (impact, scratches, etc.) and increase with increasing carbon content. By reducing carbon impurities and other scraps, the steel is made from white cast iron. Today’s steel making methods are the oxygen method, the flat heart method, and the electric furnace steel making method. Regardless of the production method used, the steel making process involves the oxidation of unwanted impurities that become slag and burn.
- Bessemer method (oxygen)
Air or oxygen is blown into a moving pot containing molten iron under pressure and oxidizes impurities.
- open heart method
Fuel and electric furnaces filled with cooled cast iron and scrap speed up the process. The heat is caused by arcing between the electrodes. Scrap is loaded. The heat generated by the arc formed between the electrodes and the iron in the furnace melts and oxidizes unwanted impurities.
- Oxygen cylinder method
It produces the same steel as an open hearth but is much cheaper. Instead, in the open-core method, alloy steel can be produced, and in the most expensive electrical method, special steel can be produced. A new method for producing steel is the jetting method, where molten iron is turned into very fine particles using oxygen pressure, which takes place in a special tank. There are two standard methods of steel production. The oxygen method is used to produce a large amount of ordinary steel, and the arc furnace method is used to produce high-quality steel, especially alloy steel.
