Process for processing stainless steel slags

摘要

A process for processing stainless steel slags, wherein these stainless steel slags are crushed to a particle size which is mainly smaller than about 60 mm at the most and wherein the crushed steel slags are processed further to produce a shape retaining mass containing the particles of the crushed steel slags in a bound state. The crushed steel slags are more particularly used for the production of asphalt. Due to the binding of the particles in this shape retaining mass, the problem of leaching, in particular of chromium, nickel and fluoride, is solved. Furthermore, it has been found that the crushed steel slags have a good cubicity and an equilibrated grain distribution for achieving asphalt with a high compression strength.
