Abstract

Steel is manufactured from pig iron containing silicon up to 1 per cent and phosphorus of about 0,1-1,75 per cent in basic converter without increasing the phosphorus content of the pig iron by using a preheated blast in the converter. If the silicon content is higher than 1 per cent namely up to 2 per cent, cold blast is used until the silicon content is reduced to 1 per cent or lower and then the preheated blast is used. The temperature of the blast used varies from 200-900 DEG C., according to the amount of phosphorus and silicon present in the pig iron and the blast may be heated in any known manner, its temperature being regulated, if desired, in any suitable manner, e.g. by the addition of cold air thereto. The tuy<\>geres of the converter are made of fireclay having an alumina content of 40 per cent.
