Abstract

Basing on mineralogical studies, the characteristic of phase composition was carried out with respect to slags after the production of cast iron and wastes from casting moulds after the production of cast steel. Their composition is dominated by glaze, metallic precipitations and oxide phases, e.g. wustite, and they contain a considerably smaller amount of silicate phases represented by olivines, fayalite or fosterite. These wastes are characterized by different phase composition or chemical composition which depends on the technological process and charge material.

Abstract

The article characterizes microstructures of metallurgic slag of varying age remaining from the production of iron and steel and the Zn-Pb ore processing in relation to magmatic rocks and ores. Based on microscopic observations - among others - hypocrystalline, hyaline and felsite (characteristic for magmatic rocks) microstructures were observed in the slag. Also microstructures related to ores, including framework and dendritic, colomorphic and corrosive structures were noted. The diversity of the microstructures presented in the article is a result of the differentiation in the formations of individual components of the slags, which depends, inter alia, on the method and the rate of cooling of the alloys.
