reducing the ore with carbon in the presence of a flux
Smelting is the process of reducing the ore with carbon in the presence of flux.
Brittleness
Brittleness
Brittleness is a property of material which breaks with little or no deformation.
Plasticity:
Plasticity is the property by which a metal retains its deformation permanently, when the external force applied on it is removed.
Examples: forming, forging, hammering
Ductility:
Ductility is the property by which a metal can be drawn into thin wires. It is determined by percentage elongation and percentage reduction in area of a metal.
Malleability:
It is the property by which a metal can be rolled into thin sheets. Highly malleable metals (like Mild Steel) are extensively used in making sheet metals.

heated slightly above the lower critical temperature and then cooled slowly to a temperature of 600 degree centigrade
Cast iron
Cupola Furnace is a melting device which used to melt cast iron, Bronze and other alloying elements are melted. It is mainly used to convert pig iron to cast iron.
Cupola furnace is employed for melting scrap metal or pig iron for production of various cast irons. It is also used for production of nodular and malleable cast iron.
