Understanding Electric Arc Furnace Steel Making Operations

A high O2 potential in the steel is beneficial for low N2 levels and the heat should be tapped open as opposed to killing the heat. At 1600 deg C, the maximum solubility of N2 in pure Fe is 450 ppm. Typically, the N2 levels in the steel at tapping ranges around 80 to 100 ppm. Decarburization is also beneficial for the removal of H2.
