Process :
- Melting : Melting of Virgin metals/master alloys or Clean and Sorted scrap of known composition in the pre-determined quantities (depending upon the buyers' specification) is done in the main frequency induction furnace and oil-fired crucible furnace.
The details of Inputs used, melting temperature, degassing temperature, degassing agents used, slag removals, sample-drawing with spectro-analysis and pouring temperature are logged.
- Pouring and Casting of Metal : Molten Metal is poured using a pre-heated ladle into permanent moulds for ingots; holding crucibles (bottom-pouring) into water-cooled moulds for billets; sand-moulds or dies for rods.
- Billet Cutting:The billets are first cut for removal of shrinkage and then cut again to obtain the desired length using the billet cutting machines.
- Rods : In case of rods production, either the sand casting or die-casting method is employed in which the molten metal is poured in the sand moulds or dies.
- Drawing/Cutting of Rods : The rods are cold-drawn thru cutting-die on draw-benches for obtaining cross sectional uniformity and good surface finish. They are then cut to remove the ends.
