Sinter, which is a mixture of iron ore, coke and limestone, and a blast of hot air.
Externally to the furnace, iron ore, coke and limestone are mixed together Intimate mixing ensures that the reactants are as close as possible to each other. This is loaded into the top of the blast furnace.
A blast of hot air ( ~ 1100 oC) is sent in at the bottom of the furnace, through tuyeres. The oxygen (air) is also one of the reactants.
The products are tapped from the bottom of the furb=nace are liquid iron and 'slag' ( calcium silicate).
The main products of a blast furnace are pig iron (used to make steel) and slag (a byproduct that is used in construction materials).
A blast furnace is given its name because it uses a blast of hot air to create high temperatures required for the smelting process. The term "blast" refers to the forced air used to increase the combustion rate and temperature inside the furnace, essential for melting iron ore and producing pig iron.
The viscosity of slag in a blast furnace typically ranges from 1 to 10 Pa.s (Pascal-seconds) at typical operating temperatures. Viscosity can vary based on factors such as temperature, composition of the slag, and other process conditions within the blast furnace.
Iron ore is used in a blast furnace as a raw material for producing iron. It is the primary source of iron, which is essential for the production of steel. The iron ore undergoes a series of chemical reactions in the blast furnace, resulting in the extraction of molten iron.
Molten iron sinks to the bottom of the blast furnace due to its higher density compared to the other materials. It is tapped from the furnace and cast into molds to solidify into various shapes for further processing.

A blast furnace is used to extract iron from its ore.
Its because air is forced into the furnace to increase temperature. Steve.
Govăjdia Blast Furnace was created in 1810.
A blast furnace is a forge in which ore is smelted to meal, being intensified by a blast of hot air.

A blast furnace.
iron is collected from blast furnace by drilling the taphole.Taphole is a hole drill and plug after cycle of time located in blast furnace bottom.
Useful Volume of Blast Furnace is the volume of the furnace from the throat level to the level where the taphole is placed. This is known the way basically because that is the region where the useful products from Blast furnace are present.
A blast furnace runs continuously, and input materials are continually dumped in at the top to make their way down through the furnace. Shutting down a blast furnace for relining or other work is a major event in its life.
