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 ...
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.

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 ...
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.

Selective crystallization of titanium-containing blast furnace slag at a temperature of 1400 °C produced a hybrid microstructure consisting of a CaTiO 3 crystalline phase and an amorphous part, and the CaTiO 3-containing mineral polymers could realize the dual functions of adsorption and photodegradation.
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).
Jan 1, 2018 · Blast furnace slag (BFS) which is defined “as the non-metallic product consisting essentially of silicates and alumina silicates of calcium and other bases, that is developed in a molten condition simultaneously with iron in a blast furnace” by ASTM C 125-16 (2016) has been widely used in construction industry for more than 80 years. When the mixture of iron-ore, coke, and limestone is placed in blast furnace, molten iron and molten slag are produced at about 1500°C temperature.
Sep 1, 2023 · Later, Chao et al. [14] reported on an automatic control system of a blast furnace that manipulates the amounts of the hot blast moisture and the injection rate of an auxiliary oil to stabilize the heat level of the furnace and to dampen the fluctuations of the hot metal temperature and the silicon content. The system comprises an adaptive autoregressive (AAR) model and a predictive self-tuning controller.
