Ironmaking Process an overview ScienceDirect Topics

04/04/2012· For example, for the ironmaking process, iron ore (sinter or pellet), coke, coal, and air blast are charged separately, but inside the BF they are mixed together, and reactions occur, such as combustion, heating-up, carbon solution loss, ore reduction, decarburization, and desulfurization of molten iron. Finally, the hot metal and molten slag are formed and tapped out periodically. The mass

Iron processing Britannica

Despite the military demand for cast iron, most civil applications required malleable iron, which until then had been made directly in a bloomery. The arrival of blast furnaces, however, opened up an alternative manufacturing route; this involved converting cast iron to wrought iron by a process known as fining. Pieces of cast iron were placed on a finery hearth, on which charcoal was being burned with a

Iron processing Iron making Britannica

Smelting reduction employs two units: in the first, iron ore is heated and reduced by gases exiting from the second unit, which is a smelter-gasifier supplied with coal and oxygen. The partially reduced ore is then smelted in the second unit, and liquid iron is produced.

1A Manufacturing Process for Iron and Steel

The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas (CO) generated by the oxidation of the carbon (C) in coke.

process begins with drilling a hole, called the taphole, into the clay-filled iron notch at the base of the hearth. During casting, molten iron flows into runners that lead to transport ladles. Slag also flows into the clay-filled iron notch at the base of the hearth. During casting, molten iron flows into runners that lead to transport ladles. Slag also flows from the furnace, and is directed through separate runners

Iron processing Iron making Britannica

Iron processing Iron processing Iron making: 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

Mercury mass flow in iron and steel production process

The iron and steel production process is one of the predominant anthropogenic sources of atmospheric mercury emissions worldwide. In this study, field tests were conducted to study mercury emission characteristics and mass flows at two iron and steel plants in China. It was found that low-sulfur flue gas from sintering machines could contribute up to 41% of the total atmospheric mercury

Direct Reduced Iron and its Production Processes

The DRI production process involves the intimate mixing of prepared (sized) iron ore with a reductant, which is also generally used for heating of the ore bed to the temperature needed to achieve adequate reduction rates. The reductant can be a gas or a solid. Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of

12.5.1.1 Sinter Production The sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. The raw materials are sometimes mixed with water to provide a cohesive matrix, and then placed on a continuous, travelling grate called the sinter

Direct reduced iron process tec-science

In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route). The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure. Just think of the complex coke production, hot-blast
