Abstract

Procedure for the preparation of lead steels, characterized in that the lead is incorporated into the liquid steel in the form of preferably spherical or approximately spherical particles, using particles of different densities, and the density of a part of the particles is greater than the density of the steel melt to be treated, and the density of another part of the particles is equal to or less than this; and lead is used in chemically combined form at least partially, and preferably in its entirety.
