Abstract

In order to contribute of the prevention of global warming, the reduction of CO₂ from the steel works becomes a major issue imposed on the steel industry. A variety of new CO₂ reduction technologies have been developed in the past decade in the ironmaking area of JFE Steel. This paper focuses on some of the technologies developed in JFE Steel, such as natural gas injection technology into the sintering bed and burden distribution control of blast furnace with coke mixed charging. The outline of the technology and the effects of application are described.
