G  Ladle Furnace    
Operating 8 ladles of approximately 85 t capacity to handle molten steel from the EAF
Also one ladle furnace, commissioned from Tagliaferri, it is equipped with a 18 MVA transformer
Whilst at the ladle furnace, the liquid steel is reheated, homogenised through a stirring process and chemically trimmed by a further addition of alloys
Chemical composition and temperature are controlled by spectrographic analysis of test pieces.
