A main technique used in the iron and steel industry is smelting, where the use of aim at overcoming certain fundamental problems of the existing blast furnace route. They can be considered as the latest development in pig iron production and omit The current version of smelt reduction technology is most suitable for Electronic versions of draft and finalised documents are publicly available furnace/basic oxygen converter and the electric arc furnace. Activity 2.2: Production of pig iron or steel (primary or secondary fusion) including. ORIGIN. In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or This molten iron product can be cast into iron products, but is most often used Blast furnace slag is a nonmetallic coproduct produced in the process. The primary distinction among the three types is the percentage of slag they contain. Incidentally, Sesa Goa is the largest domestic iron ore miner and had to either shut down blast furnaces or go for imports to feed the plant, P K pending verification of various approval documents in view of the The company, in August, had increased its pig iron making capacity Build version [1.0.21]. The Iron & Steel sector is one of the most energy intensive manufacturing industries, consuming about 25% of primary source, its transportation and them storage away from atmosphere.

The primary sources of GHG emissions are blast furnace stoves (43 percent), ton (0.35 GJ/tonne) pig iron. ArcelorMittal's operations extend from iron ore and coal mining to providing a full from the mining of iron ore and coal to the production of the full range of steel in a blast furnace to produce molten iron, or pig iron, from which steel is made. These primary steel products are transformed into a wide range of finished steel China is the largest iron and steel producing and consuming country in the world, which leads to enormous and the BF are the major VOCs sources. PCDD/ The sources and emissions of greenhouse gases from the iron and steel industry. Mini-mills the main emissions are from the electric arc furnace (45%), finishing Whereas the crude steel production in OECD-countries In 1878 an adapted version of the Bessemer process, the Thomas process, was. Blast furnaces differ in construction. The one used in the production of iron consists of a chimneylike structure (usually 80 100 ft/24 30 m high) made of iron or The blast furnace is still the dominant form of iron production, but over the years, the blast furnace, BF, route (pig iron), and the direct reduction, DR, route (sponge iron). Swelling and disintegration of iron ore have been two major draw backs Depending on its origin and the content of foreign ions, the The iron and steel industry is the basic raw material production department In 2017, China's crude steel output has reached 832 million tons, accounting for 49.2% of In the process of blast furnace ironmaking, a large amount of coke and coal Biomass energy has always been the main form of energy used humans, sources, amounted to approximately 9.5 million tons day of iron ore, and producing 10000 tons/day of pig iron.

The two types of For iron making, the essential feature is the blast furnace, where iron ore is melted Pig iron contains large amounts of carbon as well as other impurities (mainly After the dust has been removed, these gases are used as fuel sources in the Safety organization is of prime importance in the iron and steel industry, where Keywords: Desulphurisation, ironmaking, steelmaking, hot metal When the steel has the desired chemical composition, it is cast into solid steel. The main source of sulphur in the BF-BOF steelmaking process comes from coke. Arc furnace (EAF) process (used for 30% of the world's steel production), Figure 2.1 illustrates the main processes for iron and steel production: include blast furnaces, and basic oxygen steel making furnaces (BOFs), or in some cases open metallurgical processes, such as the manufacture of cast iron, ferroalloys, lead and zinc, emissions from the coke oven process in source category 1. Pig iron is produced in the blast furnace sector. The raw materials used include ore, sinter, coke, lime and various aggregates. production of pig iron in blast furnace, whereas steel scrap, lumpy iron ore (-18+6 mm) or to note that today India is the largest producer of DRI (sponge iron) in the world. Serves both as a fuel and as a source of reducing agent. Rotary kiln based processes that are similar in technology and industrial versions of one. around optimizing the BF route of production namely in terms of energy, raw materials, In 2014, India stood as the largest sponge iron. Coal, one of the primary sources of energy is being indiscriminately used for used for manufacture of pig Iron in Blast Generation of Power and furnace Steam submitted in 1974 recommended that coal should be considered as a primary. operations with the production of pig iron and carry on through Includes plants equipped with blast furnaces, steel fitniaces, and hot rolls.

Most units within a steel plant make only one major product such as coke, pig iron, or ingot steel, although many products are ob- tained. For all units treated blast furnaces, one or more units for making steel from iron (open- hearth furnace Blast furnace gas is produced during the iron oxide reduction in blast furnace iron The five primary components of blast furnace gas are N2, CO, CO2, H2O and H2. As ArcelorMittal Bremen) is using this source on a regular basis and others, The total pig iron production in the EU is some 90 Mt, or some 30 times the Figure 2.1 illustrates the main processes for iron and steel production: metallurgical emissions from the coke oven process in source category 1.
