HOW A BLAST FURNACE WORKS Foundry Gate

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.

RECOMMENDED GUIDELINE FOR IRON & STEEL SECTOR

3. PROCESS In the Blast Furnaces (BF) liquid iron (popularly termed as ‘Hot Metal’) is produced by the process of reduction at high temperature from raw materials like iron ore, base mix, sinter, coke, fluxes (limestone / quartzite), etc. &also air blast / O2. In blast furnace the process is also known as

Ironmaking 101 From Ore to Iron with Blast Furnaces

Oct 10, 2017 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.

Blast furnace metallurgy Britannica

Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends from

THE BLAST FURNACE IRON PRODUCTION

Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.
