    1. For liquid to solid transformation surface has to be created which requires energy called surface energy.So to create that surface,driving force is required which comes from undercooling(delG will get negative).

      • The process of under cooling of the cast iron is a long process of any iron foundry in India that is being carry out for the manufacturers of the products like manhole covers , tree grates , Automotive parts and many more.
      • Under cooling is the initial low temperature reached below the equilibrium solidification temperature, before the reheating of the iron.
      • Once solidification starts, it releases heat and the temperature of the system rises to the steady state solidification temperatures. This rise in temperature is called recalescence. The amount of recalescence indicates the effectiveness of the inoculation.
      • While phase diagrams help us understand the different phases that are formed during controlled slow cooling of the system, the concept of under cooling is very important, because it reflects more accurately what happens to a casting cooling in the mold.
      • The Cupola Furnace Operations course aims to provide cupola operators and other interested individuals a basic understanding of the cupola furnace and how it operates. This course focuses on the melting process of the cupola, its method of heat transference, as well as the chemical reactions and gas reactions that occur within the furnace. There is also an examination of cupola turnaround procedures, operating procedures, and control tests that should be performed to run the cupola efficiently and consistently.
