The Blast Furnace

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. the raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.,reduction of iron ore pellets, sinter, and lump ore under simulated blast furnace ,  a blast furnace (bf) is the dominant process for making iron in the world. the bf is charged with metallurgical coke and iron burden materials including iron ore pellets, sinter, and lump ore. while descending in the bf the charge materials reduce. the ironbearing

Blast Furnace Operation Extracting Iron From Iron Ore Using A Blast Furnace

  extracting iron from iron ore using a blast furnace. the common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. coke is produced by heating coal in the absence of air. coke is cheap and provides both the reducing agent for the reaction and also the heat source - as you will ,direct reduced iron process,  in contrast to the blast furnace process, the direct-reduced iron process operates at temperatures of up to 1000 c. the iron ores are therefore not melted! this also applies to the gangue contained in the ore, which is why the iron ores used must be relatively low in gangue from the outset. the reduction gases only dissolve oxygen from the

Gcse 2. Blast Furnace Extraction Of Iron Recycling, Steel Making Reduction Of Haematite Ore

2a. extraction of iron in a blast furnace sadly, now shut down! raw materials: iron ore e.g. haematite ore (iron(iii) oxide) the source of iron. fe 2 o 3 or magnetite ore fe 3 o 4 coke (carbon, c), both fuel and reducing agent. hot air (for the oxygen in it) to burn the coke ,midrex technologies, inc.,  the shaft furnace is where iron ore is converted to metallic. iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. as the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high h and co content.
