Removal of Alkaline Compounds from Blast Furnaces by Means of Slag

  • Published:
Steel in Translation Aims and scope

Abstract

A method is proposed for assessing the alkali capacity of blast-furnace slag so as to maximize the extraction of alkali oxides with the slag. In that way, blast-furnace performance may be optimized.
