Dri fines products in the global market in 2020
Pellets are pellets made from fine iron ore and other additives that are first raw and then cooked and hardened; It is used for the reduction of the traditional method of iron production in the blast furnace or various direct reduction methods.

What is direct reduced iron?
Direct reduced iron, also known as sponge iron, results from the direct oxidation-reduction of iron ore to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many minerals are suitable for direct reduction.
Direct reduction refers to solid processes that iron oxides to at temperatures below the melting point of iron. Reduced iron gets its name from these processes, an example of which is heating iron ore in a furnace at temperatures above 800 to 1200 ° C (1470 to 2190 ° F) in the presence of a synthetic gas reducing agent, a combination of hydrogen and carbon monoxide. .
The production of sponge iron and its subsequent use was the first method of obtaining iron in the Middle East and Europe, where it was used until at least the sixteenth century. There is evidence to suggest that the bloom method was also used in China, but China built blast furnaces to make cast iron by 500 BC.
The advantage of the pure iron furnace method is that iron can be obtained at a temperature lower than the furnace, only at about 1100 ° C or approximately. The problem with is that only small quantities can be fabricated at a time.
Direct reduction processes are roughly divided into two categories: gas-based and coal-based. In both cases, the purpose of this process is to expel the oxygen contained in the various forms of iron ore (rock size, concentrate, pellets, mill scale, furnace dust, etc.) in order to convert the ore into metallic iron without melting it. Slowly (Below 1200 degrees Celsius (2190 degrees Fahrenheit)).
The direct reduction process is relatively efficient. Steel made using direct reduction requires a significant amount of fuel, because a traditional blast furnace is not required. Direct reduction is usually done using arc furnaces made of steel to take advantage of the high heat generated by the direct reduction product.
Global demand for dri fines in 2020
Direct reduction iron is successfully produced in various parts of the world and enables the production of specialized iron and steel products in a decentralized manner (separately with the centralized model of the older furnace called “steel complexes”). Initial investment (CAPEX) and operating costs (OPEX) of direct reduction plants are lower than those of integrated steel plants and are more developing countries where high-grade coal coke production is limited, although steel scrap is generally Available for recycling.
