The BFBOF route produces steel predominantly using raw materials such as iron ore, coal, limestone and recycled steel. About 75% of steel is produced using the BFBOF route. First, iron ores are reduced to iron, also called hot metal or pig iron. Then the iron is converted to steel in the BOF.
The manufacturing process of iron with the use of refined ore and some other processes which includes: charging of the blast furnace, separating of iron from slag and treating the gasses. Charging the blast furnace: After ore have been poured into the blast furnace.

manufacturing. Kumba is in the process of preparing more ... industry and typically involves smelting to convert iron ore into pigiron (in South Africa primarily via the blast furnace route) and then refining (eg using a basic oxygen furnace) ... Although this process uses small quantities of iron ore,
The production of steel products from iron ore involves two separate steps: ironmaking and steelmaking. Each of these is described in detail below. Iron blast furnaces prod uce molten iron (pig iron) that can b e cast (molded) into products ; however, the majority of pig iron is used as the mineral feedstock for steel production. Steel
Oct 02, 2014· The basic materials used for the manufacture of pig iron are iron ore, coke, and limestone. The coke is burned as a fuel to heat the furnace; as it burns, the coke gives off carbon monoxide, which combines with the iron oxides in the ore, reducing them to metallic iron.
As such, the steel manufacturing process begins by smelting iron ore (Fe 2 O 3 or Fe 3 O 4) in a blast furnace. This smelting process melts out and separates iron from the original rock material. Iron ore is mixed with coke, a form of very pure coal.
Iron processing Iron processing The metal: Most blast furnaces are linked to a basic oxygen steel plant, for which the hot metal typically contains 4 to percent carbon, to percent silicon, percent sulfur, to percent manganese, and percent phosphorus.
manufacture of iron ore involves the process is creaphilbe. Steelmaking Wikipedia Steelmaking is the process for producing steel from iron ore and scrap In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium and ...
Steelmaking is the process of producing steel from iron ore and quality of the products cast skip the process of manufacturing pig iron pellets that is . ... The smelting and refining process for iron and steel in the BFBOF process involves the carbon reduction of iron ore required products Steel .
Jun 21, 2016· What Is Steel making process? Steel making is the method of processing and producing steel from iron ore and scrap. It focuses on removing the slugs and other unwanted materials like phosphorus, sulphur, silicon, nitrogen, and excess carbon from the raw iron.
The mining of the Sanje Hill iron ore initially through the mountaintop mining and then open pit mining for the subsurface deposit. The SL/RN coalbased direct reduction process for the conversion of iron oxide ore with coal around 1000 degrees C into sponge iron or direct reduced iron (DRI);

The manufacture of coke from bituminous coal is a distillation process. The impurities are driven off leaving coke. Pig Iron Processing Procedure. The pig iron is then processed for purification work for production of various kinds of iron and steel in form of ingots (large sections) using different furnaces.

Almost all iron ore is used in blast furnaces to make pig iron, which is the main material for steelmaking. Small amounts of iron ore are used in other applications such as coal wash plants and cement manufacturing. Iron is the most used metal accounting for about 95% of total metal tonnages produced worldwide. Hematite is an iron oxide mineral ...
Sintering is a process used to agglomerate iron ore fines in preparation for blastfurnace smelting and is usually carried out at iron and steelmaking centres. It involves the incorporation of crushed limestone, coke and other additives available from iron and steelmaking operations.
