摘要

Ironmaking is the art of removal the arch-enemy oxygen from iron ore by means of carbon reduction and thus producing hot metal. Steelmaking is the art of removing carbon from liquid hot metal by means of best friend pure oxygen, followed by alloying and deoxidation - where oxygen returns to be the archenemy. Non-metallic particles in steel such as oxides can have a detrimental effect on the steel product properties in terms of formability, strength and surface properties. An overview of the battle for clean steel production is given based on the experience of the author in industry as well as university research.
