Why is a blast furnace called blast furnace?
how does the blast furnace maintain the heat ?what is the function of CaCO3 ?how the slag protect the molten iron ?why does iron flow down to the bottom /how does the slag and molten iron get seperated ?what is use of waste gas /what is main impurity of iron in blast furnace ?
What are blast furnace and crucible furnaces?
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.
Uses of pure iron?
Pure iron is used to make various products such as cookware, tools, and machinery due to its high tensile strength and durability. It is also used in the production of steel, as an alloying element to improve its strength and corrosion resistance. In the electronics industry, pure iron is used in magnetic applications such as in transformers and electric motors.
Why is electrolysis much more expensive than using a blast furnace?
electrolysis requires a lot of electrical energy, however this is not the same with reduction with carbon (blast furnace), which is a lot cheaper than electrolysis, but not always the most practical. :)

Uses of waste gas in blast furnace?
none
Who is charcoal?
charcoal is a processed wood. it uses in blast furnace as a fuel

The processes of extracting and processing iron ore?
Iron ore is extracted via mining methods such as open-pit or underground mining. Once extracted, the ore is crushed and then separated from impurities using magnetic separation or flotation. The refined iron ore is then processed in blast furnaces to produce molten iron, which is further refined into steel.

Why is iron cheaper than other metals by using the blast furnace?
Partly due to scale of manufacture, partly due to the cheap and simple method of extraction from the ore, partly due to the ease with which the adundant ore can be mined, partly due to the high (compared to many metals) metal content of ores.

Why is a blast furnace called a blast furnace and not a furnace or fire furnace?
The basic concept of a blast furnace hasn't changed in more than 100 yrs. Modern furnaces are of course more complex due to newer technologies. First of all the furnace is basically a steel tank, inside it is lined with brick or gunite. The outside shell is protected from the heat by hundreds of "coolers" which are located around the entire furnace. Coolers are usually made from copper and have water inlets and outlets; water does not enter the inside of the furnace but is circulated in a closed loop system through a network of piping. At the bottom of the furnace are openings called tuyeres (ta-weers) through which hot air is blown into the furnace. The tuyeres are connected to a large brick-lined pipe called a bustle pipe. The bustle pipe is connected to a series of very large stoves. Outside air is fed into the stoves where it is heated. The heated air is then blown into the bustle pipe, through the tuyeres and into the furnace. The tuyeres can also be piped to allow the use of oxygen, pulverized coal, and natural gas to enhance the heat. Raw material is loaded into the top of the furnace by conveyor or a skip car which runs on a track pulled by cables. The raw materials are iron ore, limestone, coke and alloys chosen by the steelmaker. At the bottom of the furnace is an opening called the tap hole. The tap hole is plugged by a machine called a mud gun, the mud gun is loaded by hand with "mud" which is a high grade refractory that does not melt under the intense heat. After the materials reach the desired temp (usually about 3500 deg F) another machine called a tap drill drills out the mud to let the molten metal out of the furnace; this is known as "casting". Molten metal and slag are separated by a series of channels, slag (girl) will flow to a pit or slag car to be carried away. The slag is cooled to be used in a variety products such as an additive in concrete. The metal is channeled to bottle cars to be transported to different areas of the mill for processing. This is a very basic overview of a blast furnace, they are highly complex and very dangerous!

How do you make iron ore on Minecraft?
To get iron ingots, first make a pickax, then go digging. try to find iron ore, which has a tan colour on top of the regular stone. Mine it, then go back to your furnace and smelt/cook it into an iron ingot. Happy Mining! :)
A condensing gas furnace uses from a condensing type heat exchanger to increase the furnace efficiency?
Yes
