Abstract : the main reasons of ladle lining damage and the factors affecting extra - low ferrochromium production with perrin process are analysed , and the measures to prolong ladle life are put forward 文摘:分析了熱兌法微碳鉻鐵生產(chǎn)中,反應(yīng)包襯損壞的主要原因及其影響因素,提出了延長反應(yīng)包壽命的措施。
In order to realize the on - line prediction the baking temperature of ladle lining , and to study its temperature uniformity , a 3 - d transient mathematical model with multi - inlet and multi - outlet of ladle heating facility facilities was built 摘要為了對鋼包的烘烤溫度進行在線預(yù)測,筆者耦合了流體流動、燃燒和換熱過程,建立了多入口、多出口的三維非穩(wěn)態(tài)鋼包烘烤數(shù)學模型。
Such measures as raising baking temperature of ladle , quickening thermal circulation of ladle , adding insulating lay in ladle lining , adding cover in molten steel surface , adding ladle cover in casting are introduced to reduce molten steel temperature drop in this paper 闡明了通過提高鋼包烘烤溫度、加快鋼包熱周轉(zhuǎn)、包襯加隔熱層、鋼水表面加覆蓋劑、澆注鋼包加蓋等減少鋼水溫降的措施。
Using cfx4 . 3 code with finite difference and simplec methods , the temperature distribution of ladle lining baked at different preheating temperature of combustion gas was studied numerically and experimentally 利用計算流體力學軟件cfx4 . 3 ,采用有限差分方法和修正的速度壓力耦合算法simplec ,計算了某廠蓄熱式鋼包內(nèi)襯的溫度分布,重點分析了不同氣體預(yù)熱溫度下鋼包內(nèi)襯溫度的變化規(guī)律,并進行了實驗驗證。
