Dri fines Wholesale price in 2021

The brief introduction to dri finesWholesale price of dri fines in 2021

Today, sponge iron (DRI) is one of the most important ferrous sources in the steel industry and due to the characteristics of this product such as high porosity and absorption of moisture and oxygen, high ignition conditions, mechanical durability and abrasion resistance. Rare causes problems with the storage and transportation process, and therefore requires more precise safety measures to protect it.

The brief introduction to dri fines

The brief introduction to dri fines Sponge iron oxidation reduction processes:

  • Protection in the silo by neutral gas.
  • Protection by sodium silicate.
  • Natural protection in covered warehouse.
  • Protection by creating a coating layer with lime and briquette.

The process of preserving sponge iron in a silo is to passivate it.

Passivation: An oxide layer forms on the surface of the snail iron which prevents it from being completely oxidized. These conditions work well if there is no relocation. Because displacement and wear cause separation of the oxide layer, increase the production rate and decrease the degree of metal DRI. In methods of protection with sodium silicate and coating with lime, a protective layer is created on the sponge iron, which reduces its chemical interactions.

It should be noted that in these methods, if the snuff iron is moved, it is possible for the protective layer to separate from the DRI surface and come into contact with air and oxidation occurs. It is noteworthy that the use of sodium silicate and lime increases economic costs. What is a briquette? Briquette is the same as snuff iron (DRI) and the only difference is that it is compacted during production.

Types of briquettes based on the type and temperature of the production process:

  • Hot snuff iron briquette.
  • Soft sponge iron briquette
  • Cold iron snake briquettes.

The largest producers of sponge iron in the world are Iran and India. Isfahan Mobarakeh Steel Company is the largest producer in the world. Briquetting is the most effective way to reduce the oxidation of snail iron during storage and transportation.

The most important reason for the expansion of the sponge iron briquetting industry is the production of products with good quality and easy storage and transportation capabilities. Briquetting reduces porosity (separation) and surface area and increases the density and wear resistance of snail iron. SNFJ hot iron briquette (HBI) was used in the world steel industry (since the 70’s) Cold iron and carbon briquettes (CBIC) were created in recent years by Iranian experts. Equipping the direct reduction unit with a cold snuff iron product with a hot briquetting system was fraught with problems.

At this time, the importance of the emergence of sponge iron cold briquetting technology became apparent because it has more advantages than hot sponge iron briquetting, its carbon content is higher and its production costs are lower. Therefore, with the use of this technology, the process of storage and transportation of sponge iron to steelmaking units was done better and the country’s sponge iron exports grew significantly.
