Process
Incoming scrap is analyzed for chemical composition during unloading of truck. The unloaded scrap is then segregated for unwanted material like Cast Iron, non-metallic, non-ferrous, etc.

The selected scrap is then weighed and then transferred to Induction Furnace for melting.

Selected scrap and Sponge Iron (In-house production) is melted in Induction Furnace. Slag is removed at regular intervals and a sample is taken 2-3 times during melting for Spectrometer Analysis.

Once we achieve the required Carbon level then de-oxidation is carried out.

The liquid metal is then tapped into Ladle with purging arrangement.

Secondary refining is done in LRF.

Following is carried out in LRF:

  • Raising or maintaining of Temperature
  • Sulphur Removal
  • Micro alloying of elements
  • Homogenization of temperature
  • Homogenization of chemical composition
  • Inclusion removal
  • Holding for sequence casting
Liquid metal brought to CCM for casting into required size of Billets. The CCM is fully PLC controlled for controlling all Casting parameters.

The sizes available in Electro herm are:

  • 100 x 100 mm2
  • 110 x 110 mm2
  • 130 x 130 mm2
  • 160 x 160 mm2
  • 200 x 200 mm2
After inspection and surface grinding, wherever required the billets are sent to either market or to Rolling mills in the required lengths.
