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.
it is tappered to accomodate the gradual volume expansion of the solid charge as it descends through zones of Stack,from top to bottom in the stack the temperature gradually increases and we need to ascertain smooth burden descent.
Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie
Blast furnace = Hochofen
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.
A blast furnace is a type of furnace used for smelting to produce industrial metals like iron. It uses a continuous supply of air blown into the bottom of the furnace to create high temperatures for the chemical reactions to take place. A crucible furnace is a small, cylindrical furnace used for melting substances like metals for casting. It is lined with refractory material and can reach high temperatures quickly due to its compact size. This type of furnace is commonly used in laboratories and small-scale metalworking operations.
