Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron …
Shaft injection of reducing gas into ironmaking blast furnaces (BF) helps mitigate BF carbon footprint. However, its effectiveness relies on the interaction between shaft-injected gas (SIG) and ...
ABSTRACT. The steel industry accounts for 5% of the world's total energy consumption and contributes 6% of the world's anthropogenic CO 2 emissions. The control of CO 2 emissions has become increasingly stringent in various countries. The most advanced CO 2 emission reduction technology in the steel industry has reached a …

A blast furnace produces pig iron (PI) with the following composition: 4.5% C, 1.0% Si, 1.0% Mn, 93.0% Fe, and 0.50% of other elements. A slag (S) with 48.0% …
Blast furnace (BF) ironmaking requires flexible and precise burden distribution. As a critical distributing unit, the angle diagnosis of the BF chute is essential for operation under severe conditions. However, the existing methods must be performed during BF overhauls, which cannot satisfy timely and convenient diagnosis requirements. Inspired by cutting …

A series of slags can be formed in the lower part of the ironmaking blast furnace that play important roles in smooth furnace operation, and in determining iron quality and productivity. The final slag tapped from the BF has been investigated extensively as it can be collected directly. Unfortunately, difficulties in accessing the interiors of the …
Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks ...
