摘要

In order to obtain ultra low sulphur and nitrogen steel for producing high grade electric magnetic steel, the RH-PB(Powder Top Blowing) method was developed for use in the 160t RH. In this method, the pulverized desulphurizer is blown into molten steel from a top-blowing lance with an argon gas carrier under reduced pressure in the RH treatment.
