| Abstract: | One of the key factors to improve the bloom quality is the cleanliness of steel.Appropriate selection of the steel-making process as well as the pre-oxidizer,final deoxidizer and refining slag and their compositions will directly affect the the cleanliness of liquid steel and the quality of the bloom.In view of the deficiency of the smelting and refining processes of the GCr15 bearing steel previously implemented an optimized scheme was put forward and the industrial scale experiment carried out promptly an... |
