Dust Injection in Iron and Steel Metallurgy

Abstract

The occurrence of dusts in steelworks is surveyed. A brief overview of the European legislation situation is given. Current techniques of solid injection in different aggregates are presented. The investigations of the Department of Ferrous Metallurgy (IEHK) at RWTH Aachen University in the handling of various dusts in metallurgical processes are introduced. The dust injection into shaft furnaces and steel melts has been chosen as typical treatments. Former researches and recent works are presented and the results are discussed.
