the role of hot blast stove in slag micro

steel research international: Early View

A 3D fluid flow heat transfer model is established to study the combustion and air supply characteristics of a traditional top combustion hot blast stove (HBS). In view of the unreasonable temperature distribution in the HBS, an improved design is proposed, and its performance is evaluated and compared with that of the original design.

Extraction of Iron | Metallurgy | Blast Furnace and Reactions

A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.

The Blast Furnace

The hot blast temperature can be from 1600 F to 2300 F depending on the stove design and condition. This heated air then exits the stove into the "hot blast main" (13) which runs up to the furnace. There is a "mixer line" (15) connecting the cold blast main to
