摘要

摘要: 針對邯鋼IF鋼冶煉過程，采用統計學軟件SPSS中邏輯回歸分析、相關性統計、描述性統計等方法，研究了冶煉過程中關鍵參數和軋材夾雜缺陷之間的對應關系以及參數間的相關性.結果表明：在IF鋼冶煉過程中將轉爐終點溫度控制在1695~1700℃之間，吹氧量控制在250 m³以下，靜置時間控制在30~40 min之間，加鋁前氧位不超過3.9×10^-4時，IF鋼軋材出現夾雜缺陷的機率減少.由此對現場提出了改善措施，結果表明以上優化措施可以減少IF鋼軋材中夾雜缺陷的產生.

Abstract: Aiming at the steelmaking process of IF steel in Han-Steel, the relationship between key parameters and the defects of the rolled sheet was investigated, and the correlation among the parameters was also analyzed through the logic regression analysis, correlation statistics, descriptive statistics and other methods in the statistical software SPSS. The results show that the probability of inclusion defects in the rolled sheet reduces in the steelmaking process of IF steel when the end-point temperature of BOF is controlled in the range of 1695-1700℃, the oxygen blow amount below 250 m³, the holding time in the range of 30-40 min and the oxygen content before adding aluminum below 3. 9×10^-4. Besides, the improvement measures were carried out and the results show that the optimization measures can reduce the inclusion defects of rolled IF steel sheet.
