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.

Why cupola furnace called crucible furnace?
A cupola furnace is not the same as a crucible furnace. A cupola furnace is a type of melting furnace used mainly for iron melting, while a crucible furnace is a type of melting furnace that uses a ceramic or graphite crucible to contain the molten metal. The names reflect the different structures and functions of the two types of furnaces.
What two contaminants are usually found in the water used to cool blast furnaces?
Two common contaminants found in water used to cool blast furnaces are iron and sulfur. Iron can accumulate in the water from the contact with the metal parts of the furnace, while sulfur can be present due to the combustion of sulfur-containing fuels used in the furnace operation.
Why is the coal unsuitable for charging directly in the blast furnace?
Coal is unsuitable for charging directly into a blast furnace because it contains impurities like sulfur and ash that can negatively affect the quality of the iron produced. When coal is used as a fuel in the blast furnace, it can lead to increased levels of impurities in the iron, affecting its properties. As a result, coke, which is a cleaner form of coal, is typically used in blast furnaces for iron production.
Why is a blast furnace called blast furnace?
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.
Who first invented the blast furnace?
The blast furnace was likely invented in ancient China during the Han Dynasty (202 BC–220 AD). It was later refined and adopted in Europe during the Middle Ages for iron smelting. The concept of using forced air to increase the temperature of the furnace revolutionized metal production.

Why lead blast furnace is rectangular?
because round (mushroom furnaces) have limit in diameter of furnace, rectangular (Rachette furnace) can solve those problems

Closed container where ore is heated to extract metal?
Depending on the scale, it could be a crucible, a furnace or (only in the case of iron) a blast furnace.

What are disadvantages in steel making blast furnace?
Blast furnaces require you to go and stick dil*o up your vag, then lick my long john and give a fellatio to your cousin.

How many types of furnaces are there?
* Walking Beam Furnace * Walking Hearth Furnace * Roller Hearth Tunnel Furnaces for thin slabs * Rotary Hearth Furnaces * Pusher Furnaces
What is the Heat loss in blast furnace?
Heat loss in a blast furnace can occur through various mechanisms, such as conduction, convection, and radiation. It is crucial to minimize these losses to ensure efficient operation of the furnace and optimize energy consumption. Various insulation materials and refractories are commonly used to reduce heat loss in blast furnaces.
