Abstract

PURPOSE:To fix the S content in blast furnace slag as sulfides of heavy metals and thereby restrict formation of yellow ballas water and polysulfides affording an odor source by adding to blast furnace slag a reforming containing Fe, Mn, Mg or Si alone or a misture thereof and more than 3% of C.
