Because of the importance of the industry, the paper is valuable in engineering. the paper also discusses multi - field, multi - phase, multi - state and computer technology, so the paper is also valuable in study. in chapter 1, the background, the history and the study status of model of " flow of fluid - solid material along a curved line by stretch " are provided
論文研究流固物體曲線拉伸流動數值模擬的原理和方法，這個問題典型存在於聚合物抽絲及鋼鐵冶金連鑄工藝和加工過程中，由於涉及重要而龐大的產業，因而具有重要的工程價值，又涉及近代力學多場量、多相、多態和計算技術等綜合復雜問題，因而具有重要的學術價值。The flow field of the molten slag pool in the electroslag casting process was simulated by the finite element analysis software ansys, the simulated result was in accordance with the physical simulation results very well
採用大型通用有限元分析軟體ansys ，對電渣熔鑄體系渣池流場進行了模擬研究，所得結果與物理模擬實驗結果完全一致。In order to avoid eutectic carbide, improve nodularity, increase nodule count and increase mechanical properties, three times of inoculations were adopted in the centrifugally cast nodular iron pipes production : a ) inoculation in ladle ; 2 ) pouring stream inoculation ; 3 ) in - mold inoculation
摘要在離心鑄造球墨鑄鐵管生產中，為防止共晶滲碳體析出，改善球化，增加石墨球數，提高力學性能，採用了三次孕育： （ 1 ）包內孕育； （ 2 ）澆注時隨流孕育； （ 3 ）型內孕育。The main reason are as following : on one hand, the nd - rich phases in the hydrogen desorpted powders is so brittle that they are easily milled too fine and some are run off seriously, and then inducing low density. on the other hand, the alignment of the magnets prepared by hydrogen desorption are much low. so the hydrogen desorption process should be modified, and the solution methods can be the substitution of traditional ingots with strip cast, the enhancement of the alignment magnetic field and the addition of nd - rich phase or ( and ) lubricant before the press
主要原因是hd磁粉中的富釹相較脆，在球磨時容易被磨成超細粉而造成過量流失和使磁體燒結不夠緻密；另外一個原因是hd法燒結磁體的易磁化軸的取向度較低，為了提高hd磁體的b _ r和（ bh ） _ （ max ）可對hd工藝進行改進，改進的方法可以是用鑄片代替鑄錠，提高成型磁場強度以及在磁粉成型前加富釹相和潤滑劑。Lesoult g, catro m, lacaze j.
