Steel
the blast furnace got its name , because its bottom which is called a furnace blows hot air to go up.
the blast furnace
I think its a 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 ?
A cupola is an observation dome on a building or vehicle, and it is also a type of blast furnace.
NO!!! Its primary purpose is to REDUCE iron ore to iron. Iron ore is the commercial name for iron(III)oxide ( Ferric Oxide). (Fe2O3) In the Blast Furnace , carbon forms carbon monoxide. , from the coke(carbon) and oxygen ( hot air blast). 2C + O2 = 2CO CO(carbon monoxide) is a very good reducing agent. Hence Fe2O3 + 3CO = 2Fe + 3CO2 The CO2 is not released into the atmosphere, but undergoes reduction to form more CO. NB THere are many more secondary reactions going on in the Blast Furnace.
A salt. The type of salt depends on the type of acid.
The gas produced when sodium metal is added to cold water is hydrogen gas.
A puddling furnace is used to convert cast or pig iron (brittle) into wrought iron (maleable) by melting the cast iron, burning off the captured carbon and rolling the spongy mass or wrought iron into a ball. This first product pulled from the furnace is a "Bloom" or "Loaf" of iron that is then shingled or hammered into a billet that can be rolled in a rolling mill to produce the wrought iron. High quality merchant bars are made by cutting apart the bars, stacking them together and reheating them to welding temperatures and repeating the shingling and rolling process.
The metal produced by early metalsmiths was likely copper, due to its malleability and ease of extraction from ores.
The extraction of copper using a furnace is called "smelting." In this process, copper ore is heated in a furnace along with a reducing agent, such as carbon, to separate the metal from its ore. The heat causes the copper to melt and separate from impurities, producing molten copper that can then be refined further.
diamonds are formed from the saliva of the common warthog. when treated in a blast furnace, the fumes crystalize and result in diamond residue, which is harvested by africans, who cut their fingers, hence the name "blood diamonds".
