Blast Furnace Slag - an overview ScienceDirect Topics

2017-10-18  Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.

Air-cooled blast furnace slag (ABS)

Production and Processing Iron production is via a continuous batch process with the iron and slag produced in the blastfurnace at a temperature around 1500ºC. The furnace is fed repeatedly with materials in a sequence of a 'coke dump', followed by a 'ferrous dump'.

Blast Furnace Process - an overview ScienceDirect Topics

2010-1-1  The blast furnace process is primarily used in the carbothermic reduction of oxides, such as iron, zinc, and lead. Most of the iron ore bodies commercially explored consist of iron oxides. Consequently, rich iron ore and/or iron oxide pellets formed from concentrate can be added directly to a blast furnace (see Iron Production).

Ironmaking 101 – From Ore to Iron with Blast Furnaces ...

2017-10-10  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, which increases surface area for reactions. Magnetic separation is used to

HOW A BLAST FURNACE WORKS - Foundry Gate

2018-7-10  HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.
