What is the blast furnace?

Apr 03, 2015· A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron, but also others such as lead or copper In a blast furnace, fuel, ore, and flux (limestone) are continuously supplied through the t....

Blast Furnace Operation

The sintering or pelletising process prior to the blast furnace operation is added to allow blending of iron ores and also to control the size of the blast furnace feed Sintering or pelletising improves the blast furnace operation and reduces energy consumption Direct reduction produces sponge iron from iron ore pellets by using natural gas...

HOW A BLAST FURNACE WORKS

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...

Pig iron

The hottest part of furnace - where the walls reach a temperature >300°C - are water cooled The whole structure is supported from the outside by a steel frame The blast furnace gas that leaves the top of the furnace is a mixture of carbon dioxide, carbon monoxide, hydrogen and nitrogen and has a calorific value between 3,200 and 4,000 kJ/m³...

Blast furnace

Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide to elemental iron mixed with carbon The blast furnace operates as a countercurrent exchange process whereas a bloomery does ....
