【Abstract】 Discussions and analysis are made around the pracess factors of submerged arc refining process in LF furnace of Capital Ionr & Steel Corp. affecting the metallurgical effects such as the temperature rise of the liquid streel, desulphurization and deoxidization and it is pointed out that appropriate control of the amount and constituents of the slag withhigher basicity and lower FeO+MnO content as well as proper Ar bubbling is key to achieve the best submerged refining results.更多还原
