Abstract: 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.

Key words: FEM(finite element method), ESR (electro-slag remelting) hollow cylindrical casting, metal basin, transient, inner mold, radial deformation
