Electric Arc Furnace

This heat of steel has been melting for about 25 minutes.Both visually and audibly, the delivery of energy to the material is much smoother.

At this point, the melting steel is receiving basic additives.

High velocity oxy-methane torches pierce the protective layer of liquid slag floating on the surface of the steel bath. This allows 96% pure oxygen to mix easily with the highly reactive liquid steel.

The controlled addition of O2 combusts nearly all the carbon in the steel. Once the bath is reduced to 0.02-0.04% carbon, carbon is then injected to accurately raise the carbon back to desired levels.

Elemental composition of the bath is taken by gas spectroscopy.of direct samples. Sometimes heats are delayed while samples are being analyzed and adjusted.

The hell with waiting on a sample, tap that heat and let the LMF make chemistry! Well, introduce some reduced iron for your carbon while running the Vulcan.

nice eaf! not as cool as mine though;)  180T !!!
