摘要：

Based on discussion of the slag formation problems occurred during a commercial scale blast furnace test of 100% high Fe-content self-fluxed pellets, a proposal of replacing the charge of flux from the top by injection via tuyeres has been presented. It will optimise the slag formation process and provide a great potential of further increase productivity with smooth operation due to: 1) decrease bosh slag volume significantly; 2) obtain even and proper basicities of primary slag, bosh slag, tuyere slag and final slag formed along the height the blast furnace.
