Abstract: This paper discusses many process measures for producing low carbon,low silicon,low nitrogen and residual steel by optimizing electric furnace steel charge mixture,and selecting high quality lime and fluorite,and replacing EAF slag,and adopting four kinds of lag system,and the purification of fluorite,and full argon protection,and using aluminum particle for deoxidization during remelting process,with five harmful elements meeting the consumable electrode and ESR ingot requirements,and specifications of the rolling microstructure and non- metallic inclusions meet requirements of technical agreement.
Keywords: Low carbon; low silicon; low phosphorus; nitrogen remelting
