Abstract

Process for the metallurgical production by fusion of steels and high purity alloys with extremely low contents of sulfur, oxygen and hydrogen, characterized in that the metal melt, previously deoxidized if necessary, is exposed in consecutive time intervals, preferably in a same treatment vessel, at a different pressure, performing a degassing in vacuum to reduce the hydrogen content, while for the desulphurisation a gas overpressure is foreseen, with the understanding that the overpressure, in addition to the ferrostatic pressure that at the level of addition of the desulfurization agent, it is approximately equal to or greater than the vapor pressure of the desulfurization agent at the temperature of the melt, and this excess pressure is maintained at least during the addition of the desulfurization agent.
