Selected raw material are charged in to the Furnace. Metal is
melted to the required level.
A bath sample is taken out from the Furnace, checked for
chemical composition with the help of Spectrometer, required
additions of the alloys are made as per the required customer grade.
Again a final sample is taken out from the Furnace and checked
for correctiveness of chemical composition.
The Furnace metal is heated to the required temperature, the
temperature is checked using Pyrometer.
The prepared molten metal is poured in to the closed moulds
using preheated ladles either manually or using cranes.
