The steel industry contributes around 8% of the world's carbon emissions and is largely (73%) reliant on blast furnace and basic oxygen furnace (BOF) technologies to separate oxygen from the iron oxides that make up iron ore and produce the strong, permanent material known as steel. Making steel involves several applications of extreme heat.
See: finery forge, in which the German finery process could be managed to produce steel. blister steel and crucible steel. An important aspect of the Industrial Revolution was the development of largescale methods of producing forgeable metal ( bar iron or steel).

A STUDY ON THE ROLE OF HYDROGEN IN THE INDIAN IRON AND STEEL SECTOR 1 Currently, over 90% of iron production is through the blast furnace route, with direct reduction making up a growing share since its commercialisation in the 1970s. Since the year 2000 direct reduced iron (DRI) production has increased by 250%, illustrating the rapid growth of
iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties.
Steel Making Process : (1) Bessemer process (2) LD process (3) Openhearth process (4) Crucible process (5) Electric process (6) Duplex process.. ... Iron ore, coke (made from coal), and lime are used to make virgin steel in a blast furnace. The raw materials are placed on top of the furnace, which has a temperature of 3000 degrees Fahrenheit.
The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80100 feet high and about 25 feet in diameter (Figure 2) in which the roasted ore, coke ...

The process of making steel and shaping it into useful geometries requires high temperature and intensive energy consumption, which usually comes in the form of fossil fuels. On top of that, the steelmaking process requires breaking the chemical bond in iron ore to get access to pure iron, a reaction that requires a reagent to bind with oxygen.
At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called "pig iron.". Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. The steelmaker uses a system that bubbles oxygen through melting pig iron.

To make steel, impurities in the iron ore like, sulphur, silica, phosphorous, lime, etc. needs to be removed. It is done through the following process(a) During the iron making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes such as limestone. (b) This slag floats on the molten iron and is collected at ...

Using a watercooled lance, high purity oxygen is blown at twice the speed of sound onto the surface of the liquid iron at very high pressure. Lime is added to the process, which forms a slag and removes the unwanted elements from the liquid steel. When the oxygen blowing process is complete, the steel is poured or tapped into ladles ...
