blast furnace | Definition, Temperature, Diagrams, & Facts

Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends from ...

Blast furnace process - tec-science

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 carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking plant.At sufficiently high temperatures, the carbon can participate directly in the ...
