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.
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]
Jun 21, 2018 · In the blast furnace, the iron ore reacts with the carbon contained in the coke to form grey or white pig iron. Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent.
The blast furnace process can be briefly described as follows. Iron oxides, flux agents, and metallurgical coke are added to a skip car at the stock house. The skip car ascends through a skip bridge to the top of the blast furnace where it is emptied.
Blast Furnace Process. A blast furnace is a steel cylinder lined with refractory. It operates continuously until the lining wears out, which takes many years to occur. The term blast furnace comes from the blast of hot air that is blown into the lower part of the furnace at between 1400º to 2100ºF.
Blast furnace produces Hot metal (Liquid Iron) using Iron ore, Coke, Sinter, Pellets and fluxes such as Lime-stone, Pyroxenite, Quartzite reacting with oxygen from pre heated air.
Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day.
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.
Mar 3, 2020 · In the blast furnace process, iron-bearing materials (e.g. lumps iron ore, sinter/pellets, mill scale and steelmaking slag), coke (fuel as well as reducer) and flux (limestone and/or dolomite) are charged by the skip car or conveyor belt from the top of the furnace.
