空心环形件电渣熔铸内结晶器铜板变形有限元瞬态分析
借助有限元方法,建立含结晶器、自耗电极、渣池、金属熔池、铸锭、底垫、渣壳和气隙区的物理模型,模拟“空心环形件电渣熔铸”金属熔池形成、发展、结束过程中内结晶器铜板的径向变形.模拟与试验结果表明,当结晶器、自耗电极、渣料渣深、炉口电压相同时,一般金属熔池越浅,越容易获得良好组织;金属熔池越深且温度越高,内结晶器铜板炉后径向位移量越大;熔铸过程内结晶器铜板中部最易变形,该位置增加筋板可有效控制内结晶器铜板的炉后径向变形....

| Notes | FEM （ finite element m e t h o d）; E S R （ electro-slag remelting ） hollow cylindrical casting; metal basin; transient; inner m o l d; radial deformation 21-1344/T A physical model that includes mold,electrode,slag pool,metal basin,ingot,pad, slag shell and air gap was established by using finite element method （FEM ） to simulate the radial deformation of copper plate during the formation and development of the metal basin for ESR （ electro-slag remelting） hollow cylindrical castings. The results showed that if the voltage of the mold,the consumable electrode,the slag and the oven is equal,generally,the shallower the metal basin is, the easier it is to obtain good organization; the deeper the metal basin is and the higher temperature the metal basin is, the bigger the finial radial displacement of copper plate is,the copper plate will easily change shape in the mid height of the inner mold, where add the rib plate can control the finial radial deformation availably.
