The paper describes a method to forecast the cohesive zone of blast furnace whose shape is very important for the quality of iron and the efficiency of iron-making industry. This method builds a model that can be observed during the operation of iron making. The
The use of DRI as blast furnace feed enables reduction in coal consumption in blast furnaces. (When 100 kg of DRI is used for the production of 1 ton of molten iron, the consumption of coal in blast furnaces will be reduced by 50 - 60 kg.)
ogy, sensors now provide rich amount of online measurement of the blast furnace iron-making process. This makes the data analysis more challenging. It is imperative to establish new modeling methods for the burden distribution process. Therefore, this paper
Iron and steel making is one of the most intense energy consuming in the industrial sectors. The intensive utilization of fossil carbon in the ironmaking blast furnace (BF) is related directly to CO 2 emission and global warming. Lowering the energy consumption 2
The iron and steel industry is still dependent on fossil coking coal. About 70% of the total steel production relies directly on fossil coal and coke inputs. Therefore, steel production contributes by ~7% of the global CO 2 emission. The reduction of CO 2 emission has been given highest priority by the iron- and steel-making sector due to the commitment of governments to mitigate CO 2 emission
A ‘breakout’ is the term used to denote the conditions and results of the escape of gas and coke, or slag, or iron, from the bosh, tuyere breast, or hearth of a blast furnace. Breakouts may occur at any point below the fusion zone in the furnace, but the most of the severe breakouts are of liquid slag and of liquid iron.

Iron-making provides a vital engineering input in the process of steel production. This requires huge investment and hence, selection of an appropriate iron-making technology is very crucial in a capital scarce country like India. However, in this arena Blast furnace (BF) technology is considered as proven and the dominant one. Meanwhile, a new technology named Corex has emerged in this field

Blast Furnace Reline project and it is possible that it will not go ahead. However if it does go ahead, it will be done in conjunction with the No.5 Blast Furnace reline project. Therefore, BlueScope Steel seeks DGR’s for the following alternatives: a) DGR’s for the
Blast-furnace gas is utilized as a fuel in metallurgical works. The heat of coustion of blast-furnace gas is approximately 3.6–4.6 megajoules per cu m (850–1,100 kcal per cu m). When the blast is enriched with oxygen, the nitrogen content of the gas is lowered and the amount of other gases (including carbon monoxide and hydrogen), as well as the heat of coustion, increases correspondingly.
Historically, iron was produced in Japan by a small-scale ironmaking method called the tatara92) process with iron sand as the main raw material . Use of the blast furnace process93) began on Deceer 1, 1857 following the con-struction of a western-style

Iron and steel making is one of the most intense energy consuming in the industrial sectors. The intensive utilization of fossil carbon in the ironmaking blast furnace (BF) is related directly to CO2 emission and global warming. Lowering the energy consumption and CO2 emission from BF comes on the top priorities from both economic and environmental aspects. The BF has undergone tremendous
Blast furnace ironmaking • Carbothermic reduction of iron ore (Hametite) in blast furnace is a well known process. Overall process is written as: • Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag
1/10/2018· Annual DR iron production (86 Mt in 2017) remains small, compared to the production of 1180 Mt of blast furnace pig iron . However, an attractive feature of DR, compared to blast furnace reduction, is its considerably lower CO 2 emissions, which are 40 to 60% lower for the DR-electric arc furnace route, compared to the blast furnace, basic oxygen route [ 2 ].

The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases. The process is continuous with raw materials being regularly charged to the top of the furnace and molten iron and slag being tapped from the bottom of the furnace at regular intervals.

18/7/2013· Traditionally, iron ore has been reduced with coke in a blast furnace and the hot metal product of the blast furnace containing carbon, manganese, silicon, sulphur and phosphorous, was subsequently refined in a steelmaking furnace. During ironmaking as well as
Iron is produced either by blast furnaces or by one of seve ral direct reduction proce sses; blast furnaces, however, account for over 98 percent of total domestic iron production. 5 The modern blast furnace consists of a refractory-lined steel shaft in which a charge
A blast furnace is a special type of furnace for smelting iron from ore.Blast furnaces are very large. They can be up to 60 metres (200 ft) tall and 15 metres (49 ft) in diameter.The blast furnace is the biggest chemical reactor.Blast furnaces are also called high ovens.A
