..., with the dramatic increase in power of modern electric furnaces from around 300–400 kVA/t in the 1960s to 1000 kVA/t from the 1980s on, processes were developed with the goal of transferring the time-consuming, low-power refining activities from the EAF to other reactors. Thus, deoxidation, desulfurization...

... reactions inside a nuclear reactor. It is estimated that in the United States approximately 70% of the electricity is produced in fossil power plants, 15% in nuclear power plants, 12% in hydroelectric power plants, and the remainder from other types of sources ( Ref 3 ). This mix may be somewhat different...

... to minimize or eliminate the pinhole formation problem, a relatively simple method can be used: bubbling argon in the desulfurization reactor or ladle. When the argon is blown into the bath, the gases in the atomic form combine themselves on the bubble surface, forming molecules from the respective gases (N 2...
