The development of slag processing technology and its impact on energy-saving and emission reduction in the metallurgical industry

摘要

This study provides an overview of the production and classification of metallurgical slag and its impact on energy-saving and emission reduction in the metallurgical industry and an analysis of the impact of key factors on slag processing technology,including a brief account of blast furnace(BF)slag processing and applications with a focus on the steel slag disposal processes and the features of some typical processes.In view of the characteristics of the basic oxygen furnace(BOF)slag and the technical difficulties faced by the traditional processes,it describes the principle,features and technical advantages of the Baosteel short-flow(BSSF)steel slag treatment process developed by Baosteel.The thinking and outlook on the direction of the development of the metallurgical slag processing process are stated.
