Abstract:The melting reduction ironmaking process is the most important process route of Non-BF-ironmaking process,also is the most important research direction of the iron-making process in the future. At present,the main melting reduction ironmaking process put into commercial practice is COREX,FINEX,HIsmelt. In order to give an insight into the latest technical trends of melting reduction ironmaking in time,and targeted choose the melting reduction ironmaking process route,according to track and research the main three melting reduction ironmaking process mentioned above,the newest technical advancement of COREX process on raw and fuel optimization was introduced,on solving the sticking of the pre-reduction shaft and process controlling system optimization,and during introduction and digestion of COREX process. The newest technical achievement of FINEX process on the pre-reduction fluidized bed large-scale,the height reduce of fluidized bed system and the efficient utilization rate of energy are introduced. Suggestions and expectations for technology advancement of HIsmelt process in the future after importing HIsmelt process are made. At last,the advice in respect of raw material and fuel material condition,iron-making to steel-making process route, production equality,and other sides are proposed to choose the melting reduction ironmaking process.
