Neither endothermic nor exothermic.
These two terms apply to chemical reactions, wether they require or produce energy (heat).
Melting iron isn't a chemical but a physical reaction, a change of phase, solid to liquid.
Iron is solid at room temperature, we heat it to melt it, so heat is added (which is the same as the principle of endothermic, heat is absorbed, it must be heated)
What else can I help you with?
Is endothermic melting or freezing?
Melting is endothermic. Freezing is exothermic.
Is melting ice cubes endo or exothermic?
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
Who replaced charcoal with coak in iron melting?
Abraham Darby replaced charcoal with coke in iron melting in the early 18th century. Darby's use of coke in his furnace at Coalbrookdale revolutionized iron production by allowing for a more efficient and controlled process, leading to the growth of the industrial revolution.
What is used in the furnace to extract the iron?
blast furnace
What industrial plant is iron extracted from?
Iron is primarily extracted from iron ore in a blast furnace at an iron and steel plant. The iron ore is first processed into iron oxide, which is then reduced to metallic iron using carbon as a reducing agent in the blast furnace.
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 is cupola furnace?
In steelmaking, it is a vertical cylindrical furnace used for melting iron either for casting or for charging in other furnaces. René-Antoine Ferchault de Réaumur built the first cupola furnace on record, in France, about 1720. Cupola melting is still recognized as the most economical melting process; most gray iron is melted by this method. Source: Britannica Online Encyclopedia
What is the melting loss of steel in a cupola furnace?
First of all to correct that Cupola Furnace is used to melt Pig Iron to make Cast Iron not the Steel. As per practice the melting loss in Cupola furnace is cosiderd as arround 4.00 %. Sirajuddin Khan Bolan Castings Ltd. Karachi, Pakistan

When was Cornwall Iron Furnace created?
Cornwall Iron Furnace was created in 1716.
When was Farrandsville Iron Furnace created?
Farrandsville Iron Furnace was created in 1837.
Is melting ice cubes endo or exothermic?
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
Which exothermic reaction causes the temperature to rise in the blast furnace in reduction of hematite using coke in the blast furnace?
The exothermic reaction that causes the temperature to rise in the blast furnace during the reduction of hematite using coke is the combustion of carbon (C) in coke with oxygen (O2) to produce carbon dioxide (CO2) and release heat energy. This reaction helps maintain the high temperatures necessary for the reduction of hematite to iron.
When Natural gas is burned in a furnace is it endothermic or exothermic?
When natural gas is burned in a furnace, it undergoes an exothermic reaction, which means it releases heat. The combustion of natural gas produces carbon dioxide, water vapor, and heat energy as byproducts.
How is DRI superiour to blast furnace iron?
Direct Reduced Iron (DRI) is considered superior to blast furnace iron because it is produced through a process that involves reducing iron ore without melting it, resulting in a purer form of iron with lower impurities. DRI also has higher iron content and can be produced using natural gas, making it more environmentally friendly compared to blast furnace iron production. Additionally, DRI can be used in electric arc furnaces, providing more flexibility in steelmaking processes.
