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 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. Molten iron is produced in a blast furnace by the following steps: 1. Charge (solid …
The blast furnace is a counter-current heat exchanger used to smelt iron from iron ore for steel production. Reactions inside reduce iron oxides to molten iron and separate impurities into a slag. The furnace operates at over 1500°C, using coke as the reducing agent and limestone as a flux.
