Stabilization of Disintegrating Ferroalloy and Steelmaking Slags

KnE Materials Science / Theoretical and practical conference with international participation and School for young scientists / Pages 278–284

Abstract

High-basic refinery slags are susceptible to silicate disintegration and turn into powder at cooling, and it is the cause of a negative impact of slag disintegration products on the environment. An applied method of slag disintegration preventing is the stabilization of its structure in the process of formation or cooling. The crystallographic method of stabilization of disintegrating slags lies in introducing micro additives into the slag composition. To realize the thermal method of slag stabilization, a rotor-type installation with a ball piece is proposed. Approbation of the applied methods of disintegrating slag stabilization showed their efficiency for producing a material with a number of new technological properties and uses.


Keywords: disintegrating slags, stabilization, micro additives, rotor-type installation
