Experiment and Applications of Mg-Ca-Based Desulphurizers
-
摘要: 在真空感應爐中對Mg,Ca基合金進行系列脫硫實驗,對試樣進行化學成分分析,對夾雜物進行金相分析和電鏡觀察.并對5種不同的合金處理的鋼樣采集必要的數據進行對比.結果表明,含鎂鈣鐵合金都具有較高脫硫率,夾雜物指數以SiCgaMg處理效果較佳.Mg,Ca基合金同時具有使夾雜物變性的功能,從而改善夾雜物在鋼基體中的形貌和分布.Abstract: Some necessary data gathered from 5 steel samples treated by different alloys was analyzed through a series experiments of Mg-Ca-based desulphurizers. The results show that Mg-Ca-based alloys have the capacity of deep desulphurization. Mg-Ca-based desulphurizers can overcome the defects of boiling away easily of pure Mg or pure Ca, and enhance every elements' capacities in deoxidation or desulphurization.
