Abstract : this article gives us the new concept and its meaning of the semi - ellipse roller, and discussed the function of the semi - ellipse closing roller from four aspects, that is from increasing the pipe deformation, pipe bouncing control, improving pipe edge rigidity and stablity, and realizing the common usage of the closing roller
文摘:提出半橢圓閉口孔型新概念和其內涵，分別從增大管坯變形量、控制管坯回彈、提高管坯邊緣剛性和運行的穩定性以及實現閉口孔型輥的共用性等四個方面論述了半橢圓閉口孔型輥的作用。It also gives the semi - ellipse closing roller forming principle & quot; semi - ellipse + bouncing = round & quot;, and makes the principle formulated and quantitative for the control method and pattern of the pipe forming bouncing. this is the reasonable model for forming of thick wall pipe and high stress pipe
指出半橢圓閉口孔型輥的成型思想是「半橢圓+回彈量=圓」 ，並且使這一思想公式化、數量化，為控製成型管坯的回彈提供了方式和方法，是成型高強度厚壁管的理想模具。For membrane contactor process, the binary gas mixture diffusion through the pore channel should be considered as a transition diffusion of the absorbed momentum a through the stagnant momentum b. and the process would consist three steps : transition diffusion through the pore channel, stephen diffusion in the pore edge, and the pore interaction in the membrane surface
對于孔形狀為近似橢圓形的聚丙烯微孔膜，在研究擴散問題時，其等效孔徑可採用葉孔擴散問題中的孔形狀校正公式來計算。在膜接觸器中，氣體通過微孔膜的擴散機理為過渡擴散，其擴散過程包括通過孔道主體的過渡擴散、微孔膜出口處孔道邊緣的stephen擴散以及孔之間的相互作用。Abstract : tensile reducer is one of the necessary apparatuses during the pipe production process at present. this paper deduces a multi - variation formula by using the energy principle and adopting upper limit method. the formula can be used to calculate the parameters such as the drive power, tensile coefficient, roll speed, depth of exit pipe wall, hole type ellipse etc. the existence of minus drive power has also been theoretically calculated
文摘:張減機是鋼管生產中不可缺少的設備之一.本文從一般能量原理出發，採用上限法推導出一個多變量公式，利用該公式可求解電機功率、張力系數、軋輥轉速、出口鋼管壁厚、孔型橢圓度等參數，並且從理論上計算出電機負功率的存在In the study, an infinite plate with elliptic notch is subject to remote stresses at infinity
