Luis Verdeja. 2015. Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is studied and researched in the steelmaking industry in general, and ...

Carbonization of COKE • Well graded coal is selected • Heated or carbonized to COKE • Heated coal is cooled • And Proper COKE are fed into the Blast furnace for the ...
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.
Dear Readers, In this presentation, I have tried to explain main raw material sources of iron making process. Also, with my experience, I have tried to give a concept about the plant engineering related to raw material. I hope that, this presentation will be helpful for young engineers. With this presentation they will get a broad idea about ...
A new route for making steel from iron ore based on the use of hydrogen to reduce iron oxides is presented, detailed and analyzed. The main advantage of this steelmaking route is the dramatic ...
Modern iron making. Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an ironrich clinker called 'sinter'. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal.

A general flow diagram for the production of raw steel from iron ore is presented in Exhibit 2. In general, the process involves (1) beneficiation of the iron ore ...
Steel Manufacturing Process. To produce steel first the iron ore is heated and melted in a furnace. The impurities are then removed from the molten iron. Carbon and other required alloying elements are added to make steel. Modernday steelmaking is highly improved and specialized.
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 sinter plant turns iron ore into sinter, which is the optimal product for the blast furnace. Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an opengrained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.
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.
10. STEELMAKING • Since the mid1800s, a number of processes have been developed for refining pig iron into steel. • Today, the two most important processes are Basic oxygen furnace (BOF) Electric arc furnace • Both are used to produce carbon and alloy steel. 12.
The Production of Iron. First the ore is graded and crushed and the fine. particles sintered. Sintering is the process of. converting fine particles into a continuous mass. Iron ore powder is compacted and then heated to a. temperature below the melting point of the metal. in the ore, this results in the waste being.

How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved ...
The crucible process for making steel, introduced in England in 1740, by which bar iron and added materials were placed in clay crucibles heated by coke fires, resulted Metallurgy Iron, Steel, Alloy: From 1500 to the 20th century, metallurgical development was still largely concerned with improved technology in the manufacture of iron and ...

While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material. As the predominant production method in Europe is the conventional, coaldependent BF/BOF process, the need to assess alternative breakthrough technologies to reduce carbon ...
Steel Making Process Steps: The first step involves mining iron ore or as easy it can be described as the first step in the process of making steel from iron ore. This is a very polluting process that uses coal for blasting, etc. It releases several pollutants such as oxides of sulphur, PM, and fugitive dust.
