Abstract

Commercially operating EAF dust recycling processes were investigated by means of unit process analysis. Over 80 % of EAF recycling processes are Waelz kiln process adapted a rotary kiln as a main reactor. There are differences among these pyrometallurgical processes by plant location and timely important things such as environmental regulations. In this paper, the characteristics of each plants are analysed with the point of unit process.

전기로 분진에서 조산화 아연을 회수하는 리싸이클링 공정을 검토하기 위하여 국내 및 해외에서 가동되는 전기로분진 처리공정을 구성 단위공정별로 분석하였다. 이로부터, 조업 중인 공장 별로 가동 시기 및 공장 환경에 따라 세부 구성설비에 커다란 차이가 있음을 알 수 있었다. 따라서 새로운 전기로분진 처리설비를 설계하거나 도입할 때 필요한 설비와 반응측면에서의 기본적인 검토 인자들을 도출하였다.
