【摘要】：針對(duì)邯鋼IF鋼冶煉過(guò)程,采用統(tǒng)計(jì)學(xué)軟件SPSS中邏輯回歸分析、相關(guān)性統(tǒng)計(jì)、描述性統(tǒng)計(jì)等方法,研究了冶煉過(guò)程中關(guān)鍵參數(shù)和軋材夾雜缺陷之間的對(duì)應(yīng)關(guān)系以及參數(shù)間的相關(guān)性.結(jié)果表明:在IF鋼冶煉過(guò)程中將轉(zhuǎn)爐終點(diǎn)溫度控制在1695~1700℃之間,吹氧量控制在250 m~3以下,靜置時(shí)間控制在30~40 min之間,加鋁前氧位不超過(guò)3.9×10~(-4)時(shí),IF鋼軋材出現(xiàn)夾雜缺陷的機(jī)率減少.由此對(duì)現(xiàn)場(chǎng)提出了改善措施,結(jié)果表明以上優(yōu)化措施可以減少I(mǎi)F鋼軋材中夾雜缺陷的產(chǎn)生.
[Abstract]:According to the smelting process of if steel in Handan Iron and Steel Company, the methods of logical regression analysis, correlation statistics, descriptive statistics and so on are used in the statistical software SPSS. The relationship between the key parameters and the inclusion defects in the rolling mill and the correlation between the parameters are studied. The results show that:. The terminal temperature of converter was controlled at 1695 ~ 1700 鈩，
