A blast furnace is a reactor which produces an impure form of molten iron, termed ‘hot metal’, from ferrous bearing ores. The principal raw materials used in the blast furnace operation consist of. 1. Metallurgical coke, ferrous bearing feeds and fluxes charged via the furnace top. 2.
1 Blast Furnace Process. The blast furnace is a tall, vertical shaft furnace which has the purpose of heating and reducing iron oxides (hematite and magnetite) into hot metal which is basically a carbon-saturated silicon and manganese iron alloy with residual amounts of sulfur and phosphorus. A schematic representation of a blast furnace and ...
The ironmaking blast furnace (BF) is a very energy-intensive metallurgical process and the prime route for steel production, from which about 70% of the world’s steel consumption is produced (Geerdes et al., 2015). The BF system receives coke and ore solid raw material along with hot blast air and continuously produces hot metal as the main ...
Aug 1, 2023 · Among them, the impact of blast furnace gas is the largest at 726.08 kg CO 2 eq (28.14%), which is mainly due to the production and treatment process of blast furnace gas. Secondly, the impact of the ironmaking process and the sintering process accounted for 25.81% and 19.92%, respectively, mainly due to the large amount of waste gas generated by these two processes.

Blast furnace slag (BFS) is a by-product of iron manufacturing in blast furnaces fed by a mixture of iron ore, limestone, and coke [70,71]. In the manufacturing of iron, iron scrap, iron ore, and fluxes (limestone and/or dolomite) are discharged into a blast furnace along with coke for fuel.
Among them, Blast Furnace Gas (BFG, see Table 1) is an important by-product of its production process, with the main components of CH 4, CO, CO 2 and other gases. BFG can be used as the gas of metallurgical equipments, such as hot blast furnace, which reduces the consumption of smelting fuel and environmental pollution.

4 days ago · Blast furnace (BF) hydrogen-rich smelting has become an important way for low-carbon ironmaking. The coke gasification dissolution loss will be accelerated by H 2 O generated through hydrogen reduction, which is the fundamental reason for the limited injection rate of hydrogen-rich gas in BF. The gasification dissolution loss experiments of ...
Nov 1, 2022 · Blast furnace gas, a common by-product resource in the iron-making industry, has a high utilization value as a direct fuel or as a raw material after further purification (Li et al., 2022c). COS is the most typical pollutant in blast furnace gas, with a concentration of 86–118 mg·Nm −3 (Lu et al., 2019).
