Blast furnace metallurgy Britannica

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

Main Features of a Modern High Capacity Blast Furnace

Sep 20, 2019· Modern high capacity BFs operate with high blast temperature and low blast humidity, by adjusting the amount of PCI to control the furnace temperature. In many furnaces, the blast temperature is stabilized at 1,230 deg C to 1,250 deg C, and the moisture in blast is stabilized at 10 g/N cum to 15 g/N cum.

A Short History of Steel and the Bessemer Process

Jul 22, 2018· Blast furnaces were first developed by the Chinese in the 6th century B.C., but they were more widely used in Europe during the Middle Ages and increased the production of cast iron. At very high temperatures, iron begins to absorb carbon, which lowers the melting point of the metal, resulting in cast iron (2.5 percent to 4.5 percent carbon).

Bessemer process Wikipedia

The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.
