Abstract

In a basic Bessemer method of converting iron into steel having a nitrogen content lower than that obtained by blowing with atmospheric air, the temperature of the blast is maintained above 225 DEG C. throughout the conversion, and for at least half the total blowing time the blowing is effected with a mixture of oxygen and steam at a temperature of 250 DEG -350 DEG C. Preferably, the ratio, by volume, of oxygen to steam in the blast is between 1 of oxygen to 1,5 of steam and 1,5 of oxygen to 1 of steam. The blast may also contain combustion gases the nitrogen content of which is such that the final blast contains less than 5 per cent nitrogen and such gases may be used for preheating the steam.
