In a process for the production of steel with low hydrogen content in a through-blowing oxygen converter with nozzles arranged below the bath surface in the refractory brick lining, the nozzles composed of concentric pipes for introducing oxygen sheathed by a protective medium, and with an oxygen lance projecting into the converter opening, for a hydrogen content as low as possible of about 2 ppm maximum, at least half the total quantity of oxygen is blown onto the bath and the nozzles arranged below the bath surface are temporarily operated toward the termination of refining with a hydrogen-free gas.
