Blast Furnace Construction In America | by J. E. Johnson, Jr

The blastfurnace is the key which unlocks Nature's stores of iron for our use. It is unique in having been unchanged in principle for several centuries, and in having no substitute. For the steam engine we have the gas engine, for the Bessemer converter the open hearth, but if the blast furnace were taken from us, civilization would be halted.

Main construction features are: ` Pressure vessel with no expansion joints. ` Elimination of tensile stress impact on stove shell and hot blast trunk through a unique combination of a box girder and a hydraulic combustion chamber support system

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

TMT - Tapping Measuring Technology: Detail

By October , EVRAZ will complete a technical upgrade of No. 6 Blast Furnace of their integrated steel works NTMK located at Nizhnij Tagil in the Urals, Russia. The modernization will enable NTMK to increase the nominal capacity by about 40% compared to the previous campaign design.
