A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being supplied above atmospheric pressure. [1]
Blast furnaces are similar to furnaces, but can smelt only raw ore, ore blocks and tools / armor made of iron, gold or chainmail. Blast furnaces serve as the counterpart to smokers, which are used mainly to cook food faster. Smelting equipment yields one iron or gold nugget from their respective materials.
blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top.
Jun 21, 2018 · Boudouard reaction. The reaction of carbon dioxide and carbon to carbon monoxide and its reverse reaction is temperature-dependent and is described by the so-called Boudouard reaction. The situation can be illustrated by the evaporation of water in a closed room filled with air.
May 25, 2024 · A blast furnace is a critical installation used for the production of iron. It is designed to withstand high temperatures and chemical reactions, making it integral to the steel-making industry. This article will delve into the design elements and operational principles of a blast furnace that enable it to efficiently produce iron ...
A blast furnace is a counter-current gas-solid reactor where the ascending gas reacts with the descending solid bed, producing hot metal as the main product.
The blast furnace (BF) ironmaking process is currently the dominant process for providing steelmaking raw materials worldwide. However, the BF process relies heavily on metallurgical coke and involves cokemaking and sintering operations, which often attract serious environmental concerns.
Blast furnace ironmaking is a continuous metallurgical process in which iron ore is reduced to liquid pig iron in a blast furnace. It is developed and improved from the ancient shaft furnace ironmaking. In China, the blast furnace is named for its vertical tubular shape and slender furnace body.

Oct 10, 2017 · 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.
