The raw material for the production of steel is iron ore. Iron ore is converted to concentrate pellets to steel. Iron ores are the most important and major raw materials for pellet production. For more information about Iron pellet Exporting Countries in 2020, visit our site.
How are iron pellets made?
That is, pellets made from iron ore and other additives that are first raw and then cooked and hardened and used for reduction by the traditional method of iron production in a blast furnace or by various methods of direct reduction. Pellets are the raw material for the production of crude iron and must have good mechanical, chemical and thermal properties in regenerative furnaces.
For the production of raw pellets, the iron ore consists of additives, 90% of which are below 325 mesh. During the production of raw pellets, additives and adhesives such as calcium hydroxide may be added to increase the mechanical metallurgical properties of the pellets.
At this stage, the pellets with desirable dimensions and sufficient mechanical strength are produced and sent to the hardening or baking machine. In the second stage, the raw pellets, in order to harden in the oxidizing atmosphere, are carefully heated to below the softening temperature of the iron ore in a machine to be first dried and then cooked, so that their degree of porosity does not decrease.
At this stage, with the bond between the iron ore particles and other pellet materials, the crystal structure of the rock changes and reactions between slag and iron oxides are performed. In this first stage, the materials are exchanged with each other and neutral compounds or bases are formed between the grains of iron oxides. At the end of the cooking stage, cooling the hot pellets should be done in such a way that no cracks are created in them.
Uniform distribution of dimensions mainly from 9 to 16 mm, high porosity and uniform 25 to 30%, uniform mineral composition in the form of hematite or regenerated hematite compounds, high and uniform mechanical strength, abrasion resistance, sufficient mechanical strength even in hot stress environment Reductive and low adhesion. To convert iron concentrate to pellets, various steps such as transfer of raw materials, milling and crushing of raw materials, mixing of raw materials, production of raw pellets, pellet kiln, dusting, cooling water supply, final product transfer, water purification system, compressed and Laboratory to be done.

Main exporting countries for Iron pellet
Our pelletizing plant with an annual production capacity of 3.4 million tons of pellets from iron ore concentrate has been established. The investment of this project was provided from the internal resources of the company and the use of foreign exchange facilities in the form of financing. The product of this factory is the main raw material for the production of sponge iron, which is used in the production of steel ingots using the reduction method.
