The Blast Furnace
There is a "mixer line" (15) connecting the cold blast main to the hot blast main that is equipped with a valve used to control the blast temperature and keep it constant. The hot blast main enters into a doughnut shaped pipe that encircles the furnace, called the "bustle pipe" (13).
Glossary of Terms used for a Blast Furnace – IspatGuru
· Stockline level – For blast furnace with bell top, it is the horizontal line at the bottom of the large bell when closed. For example, a m (6 feet) stockline means the horizontal line loed m below the large bell when closed. For blast furnace with bell less top, it is the horizontal line loed m (3 feet) below the tip of the rotating chute in the vertical (90 degree ...
Blast Furnace Ironmaking
Blast furnace iron has limited engineering appliions. It is mainly for use for iron castings, and for abrasion resistance and heattransfer appliions. Most blast furnace iron is the raw material for oxygen steelmaking, where the molten iron is refined to produce the world's most popular metal for engineering appliions—rolled steel.

Blast Furnace Pressure Control Valve | TINITE
TYFZ type blast furnace pressure control valve is composed of ZAJW3 type automatic adjustment butterfly valve and pipes. The pressure control valve is applied in blast furnace and other systems that need to adjust flow and pressure to maintain stable production.
Blast Furnace
In the blast furnace there are more monolithic refractory products in continuous operation than at any other stage in the steel production process excluding new linings and interim repairs. Taphole mixes, runner mixes, assembly parts or preshapes (for example skimmer, tipping trough) are heavilyused refractory products in the production of pig steel.
Inland Steel's No. 7 blast furnace third reline ...
· Inland Steel Company operates two 1940s vintage blast furnaces and one world class furnace commissioned in 1980. A table gives a description of the small No. 5 and 6 blast furnaces and the large No. 7 furnace. Historically, the smaller furnaces were relined every four years after averaging million net tons of iron production and campaign extension was not an issue until the mid1980s. .

MAN Energy Solutions for the iron and steel industry
Large blast furnaces need powerful blowers with higher air flows to reduce iron ore to liquid iron. This process, which steel plants use to produce iron, requires especially efficient and robust air compressors. MAN Energy Solutions draws on its expertise and experience, gained from successful turbomachinery projects around the world, to bring energyefficient solutions to iron and steel ...
BLAST FURNACE RELINE PROJECT
Blast Furnaces are often subjected to extreme physical stress resulting in deterioration of the interior, thus requiring periodic repair. The major repair in a Blast Furnace's campaign life is the replacement of the lining traditionally known as a "reline". Since its commission, Blast Furnace has undergone 2 relines, the latest of which was in 1991. It is assessed that based on its ...
The High Line to the Blast Furnaces
These are pictures I took in September of 2005 of the high line from the ore pit to the blast furnaces. The wide guage electric charging larrys would carry the ore and other basic materials to the blast furnaces.
Blast Furnace operation: HOW A BLAST FURNACE WORKS
· The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron. These liquid products are drained from the furnace at regular intervals ...
