Prediction of Surplus-life for Shell of Bao Steel 300t BOF
-
摘要: 寶鋼300t轉爐爐殼使用中出現嚴重變形,危及生產.通過對爐殼變形過程監測、有限元爐殼應力分析、爐殼材料蠕變性能實驗等綜合技術手段,采用修正的θ-Conept Project方法成功地預測了轉爐爐殼的殘余使用壽命,為企業的生產計劃決策提供了有效的技術支持.Abstract: The obvious deformation occurred in shell of Bao Steel 300 tone BOF turned into a serious danger for safety production. A series of studies were carried out for determining the reason of the deformation such as finite element analysis for stress of the shell and creep test, etc. By means of these studies, the strplus-life of the shell was predicted successfully.
