Steel making process – ArcelorMittal

Steel is produced from iron ore or scrap. Iron ore is a mineral aggregate that can be converted economically into iron. The quality of the iron ore is mainly determined by its composition; a high iron content and low sulphur and phosphorus contents are favorable. Iron ore can be found all over the world, but its iron

Production

To make iron from the ore, it is reduced and melted in a blast furnace with coke at over 1300°C. The resulting pig iron contains more than 2% carbon and cannot be used for products in this form. It is only through the LD process that the pig iron is converted into steel by blowing it with pure oxygen.

 · Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the socalled direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

from Swedish steel production, and about 80% of these emissions originate from iron ore reduction. Within the BF/BOF process, iron ore is reduced to pig iron using reducing agents in a blast furnace. Furthermore, in a basic oxygen furnace (BOF) pig iron together with ferrous scrap is processed and transformed into crude steel.

A process for producing pig iron is described, which contains a reducing shaft furnace 1 and a melting gasifier 2. The sponge iron produced from iron ores in the reducing shaft furnace is supplied to the melting gasifier and converted there into a pig iron melt. The gas produced in the melting gasifier is supplied directly via a line 4 as reducing gas to the reducing shaft furnace.

 · The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.
