Learn how a blast furnace transforms iron ore into molten iron through a high-temperature reduction smelting process. Find out the main ingredients, reactions, products, and controls of a blast furnace, and its role in steel production and other industries. The blast furnace (BF) remains the predominant technology for reducing iron ore today and is expected to be a key component of the global steel industry for years to come. Modern BFs operate near theoretical efficiency limits but continue to be refined, and many innovative practices are being developed to significantly reduce their carbon ... This article comprehensively discusses and elaborates the information regarding blast furnace, its construction details, including its main parts and their working phenomenon and function. This article also highlights the application of these furnaces for its practical use. Blast Furnace and Process Description :- Iron blast furnace is a vertical shaft, which is used to melt the iron ore and to produce hot metal by heat exchange and chemical reaction. The burden charge consisting of iron oxide, flux and coke and it provides through the throat from the top of the furnace. Blast Furnace The iron oxide is reduced to hot metal by receiving heat from the ascending hot blast (oxygen, nitrogen) and injection (oil/pulverized coal) supply from the bosh region. Below the ...
