The melt shop has 2 X 60 tonne Electric Arc Furnaces (EAF), with 40 MVA Power transformer & three electrodes each having 550 mm diameter.
The EAF is designed to take metallic charges ranging from 100% scrap to 100% DRIand liquid metals(Hot Metal) in suitable combination with DRI.
STEEL FROM SCRAP ROUTE: The scrap is charged by bottom discharge scrap bucket whilst the DRI is charged continuously through the EAF water cooled roof.
STEEL FROM LIQUID METAL ROUTE: The Liquid Metal (Hot Metal) pour into the furnace with the help of Launder and DRI is charged by bottom discharge scrap bucket and also continuously through the EAF water cooled roof.
DRI ensures that lump element contamination is of no concern. Nitrogen levels at tapping are also low.
