As you know The export transition processes are not complicated in fact all of them come into the same cargo and shipment method.

direct reduced iron

Direct reduction of iron ore (DRI) or sponge iron is the result of the direct reduction of iron ore to iron by reducing the gas produced from natural gas or coal. Consider that the process is carried out without smelting the iron ore. Sponge iron is a suitable substitute for iron scrap for the production of iron and steel products. After the recycling process in the steel industry, sponge iron is found in the casting process in the form of the desired product, which can be used in the form of ingots and rebar. Sponge iron usually has the following properties:

• Quality consistency
• This type of iron lacks phosphorus and sulfur elements
• High iron content and high purity
• No lead, tin, zinc, or other toxic elements
• Very little dust absorption in the transfer path

As previously mentioned, sponge iron is usually produced by recycling coal and natural gas. This process of activating iron ore with natural gas takes place in three ways: Midrex, HYL, and Purofer. Among the three methods mentioned, the Midrex method is more widespread and popular than the others. Likewise, the iron ore recovery process is carried out using HYL and SL/RN methods using coal. teaching method: The Midrex process is one of the best for the production of iron ore regeneration, therefore the production of sponge iron is one of the most widespread methods in Iran and the world. The method got its name because it was first used by Midrex in Portland, Oregon, USA. In the Midrex method, natural gas first enters the fractured area and is then converted to hydrogen and carbon due to exposure to high temperatures and chemical reactions. The carbon and hydrogen produced then enter the reduction furnace. At the same time as the decomposed carbon enters the furnace, the iron ore is thrown into the furnace from above and eventually collides with the decomposed coal. The natural gas is heated when it enters the furnace, while iron ore loses oxygen when it comes into contact with it. As a result, the ball is in the shape of a hole made of hardened iron. This method is known in Iran and the world as a low-consuming, high-efficiency method. In Iran, most sponge iron is produced using the Midrex method. Haier method: In this method, as in previous methods, natural gas is used to recover iron ore, but there are differences in the work. In this method, the equipment and tools used and the stages in the production of the finished product are more complex and expensive than the Midrex method.

direct reduced iron process

In general, the howl method has the following properties:

• The incoming iron ore is baked in the form of round pellets.
• In this method, as in the Midrex method, cracked natural gas is used as the regenerator.
• The furnace in this process is the same as the furnace in the Medrex process.
• The regeneration temperature for this method is around 860 degrees Celsius.

sl/rn method This method is considered one of the oldest methods of rehabilitation. In this method, coal is used instead of natural gas for the process, so that the coal produces carbon monoxide gas in the furnace, and this gas causes the regeneration operation. Furthermore, this method does not produce hydrogen. The temperature of the regeneration operation is around 1100 degrees Celsius. Why is the use of sponge iron so popular? Today, the use of sponge iron in steel production plants has increased a lot, which we will mention below:

• This method is faster and more economical due to the use of scrap metal.
• The quality of sponge iron is higher than pig iron.
• Compared to traditional methods, direct cleanup methods have fewer environmental problems and limitations.
• In the direct regeneration method, natural gas can be used without removing impurities.

It should also be noted that the production of steel by the direct recycling method is also in line with the policy direction of the National Iron and Steel Corporation and the Ministry of Industry and Information Technology. sponge iron problem If sponge iron or DRI is left unprotected in a wet environment, it will rust like other steel products and generally corrode faster than steel. Unlike furnace cast iron, which is almost pure metal, DRI contains some silicon impurities that must be removed during the steelmaking process. According to the statistics I have published on the subject, India is the largest producer of sponge iron.

direct reduced iron in export

direct reduced iron is just one of the methods used in manufacturing and preparing sponge iron for export. Iron ore pellets are obtained by direct reduction of 67% iron ore (oxygen is removed during the direct reduction operation without melting the iron ore), from which porous pellets or sponge iron are obtained. In industry, the material is melted and regenerated into plates, billets, and rebar in the casting process. Sponge iron has the appearance of a spherical block with a spongy and porous appearance, hence the name sponge iron. Today, high iron grade sponge iron is more popular due to the scarcity and increasing price of scrap iron as well as environmental concerns. As previously mentioned, the iron sponge is obtained by processing that does not reach melting temperature or recovery of natural iron minerals. The high quality of sponge iron makes it a suitable source for steel production. In Iran, iron ore extraction is usually done using Midrex technology. In the Midrex technology, iron ore pellets are regenerated directly by crushing gas. In this way, the natural gas first enters the reformer (gas fracturing unit), where it is broken down and separated into CO and H2 due to the presence of special catalysts and the influence of heat. The released carbon monoxide and hydrogen enter the reduction furnace where they combine with the available oxygen in the molten pellets to reduce the iron ore. In this method, 67% of iron ore pellets are regenerated and porous pellets (iron sponge) are produced by Fe metallization (close to 92 degrees). Without going through the cooling section of the furnace, it is transported to the steel making section through a special material transport system and directly loaded into the furnace, and the products with a temperature close to 600 degrees Celsius are produced in the regeneration unit. The sponge iron used in the factory is spherical and mushroom-like in appearance, so it is called mushroom iron. This material, which produces about 5% of the world's steel, is high in iron and is one of the most widely used products in the steel industry.

Sponge iron is one of the raw materials and products made from iron concentrate without smelting. That is, this substance is obtained during the recovery of iron ore. As we all know, the production methods of sponge iron vary widely. But among these methods, one of them is called the most common and suitable method. For this reason, the method has a wide range of advantages and characteristics and is accepted by everyone and manufacturers. Another method of producing this iron is through the direct regeneration of iron ore. That is, in these methods, iron ore is shaped into a spherical or spherical shape. The stones then become spongy and have small holes. Therefore, it can be said that the appearance of this iron, namely its spongy and small pores, is the origin of its name. The iron quality of this iron is very high. For this reason, one of the reasons for its widespread use is the lack of waste such as scrap iron. As mentioned above, the method of direct recovery of iron ore is called sponge iron. That is to say, this method produces sponge iron without melting iron ore. Therefore, the English root of sponge iron is the direct recovery of iron ore. After being melted and regenerated in steelmaking, sponge iron is used in the casting process in three forms: plate, billet, and rebar. About 5% of the world's steel is now obtained from DRI (sponge iron), and this trend is increasing. Pellets are compositions of iron made from the concentration of iron ore (concentrate). In the production of DRI, approximately 1.45 tons of pellets are used per ton of product. Methods for producing sponge iron from concentrates and recycled materials + advantages and disadvantages of each method As we mentioned above, the manufacturing method of sponge iron can vary. But the most important stage in production is the production of sponge iron using natural gas, thermal coal and Medrex's direct regeneration method. In the method of producing sponge iron using natural gas and thermal coal, the iron ore silt is destroyed at the lowest temperature. This means that you can say that the oxygen in the iron ore is removed at a temperature lower than 1100 degrees Celsius. In addition, sponge iron is today also produced from concentrates and recycled materials using advanced methods that have been created. But in the Midrex method, which is considered the most important and common method of making mushroom iron, it depends on the location of the plant and its available resources.

direct reduced iron uses

In other words, among the most important and most used methods for the production of sponge iron we can mention the following: In the Midrex production method, iron ore is regenerated without an intermediary. Because their grade is 67%. That is, natural gas produces two gases based on heat, which enters the furnace. These gases are then mixed with the oxygen in the molten iron ore to regenerate the iron ore. This is how high-quality mushroom songs are made. It has been known and widely used in production methods for tunnel kilns since the 90s. For this purpose, it is used as a small method for the production of sponge iron. One of the advantages of this method compared to other methods is that it is more stressful to perform the resuscitation method. This means that the revival method is performed at a higher speed. On the other hand, it can be said that the output from such a furnace is in the form of a solid tube/cylinder whose diameter can vary. As sponge irons require investment, they are designed and produced on a small and appropriate scale. But without a doubt, this small size is what makes these types of metals special and attractive. We know that the production of fungal iron in a plant depends on many factors. Probably the most important factor is the availability of natural gas and coal. Therefore, the production of sponge iron depends on these two factors. That is, the higher the amount of these two fuels used in the factory, the higher the production of sponge iron and vice versa.

direct reduced iron price per ton

According to reports published so far, more than 90% of factories in various countries use these two fuels (coal and natural gas) to produce various types of sponge iron. In fact, they can manufacture this product using iron ore concentrate and recycled materials. Therefore, these two factors play a large role in the rise and fall of the production of sponge iron. In addition, manufacturers can estimate their production by taking into account the factors involved in the production of sponge iron. Also by considering the cost of producing its profit is calculated and determined. As we all know, after producing sponge iron, the manufacturer checks its properties. In fact, they tried to determine all the specifications and properties of this iron (such as purity, quality, hardness and density). In addition, measures should be taken to prevent this valuable product from oxidizing, and for this reason, sponge iron is usually stored in covered warehouses. Next, the product is acquired by the merchant or the steel mill and transferred to the steel mill for further operations on it. Often, manufacturers use traditional and new methods to transform sponge iron into steel. This means that they choose sponge iron as raw material for steel production. Then at this stage, the type of steel for making steel and its physical/chemical properties are determined. It can also be said that in this method the manufacturer places sponge iron in various proportions in an arc furnace and transforms it into steel in the process. Then, depending on the desired quality and type of steel, additives are added to it so that the steel produced is acceptable in the required standardized tests. Additives added to molten steel are dispersed uniformly out of the gas and combined with each other during heating. Most manufacturers use this method to convert sponge iron into molten steel, which is said to have many advantages in addition to simplicity.
