The purpose of this paper is to discuss solidification and mechanical characteristics in the strip casting process by the twin roll method. Interaction of temperature fields between the strip and the cooling roll is taken into account by the substructure method when solving the heat conduction equation under steady state. Simultaneously, in order to verify the results of a simulated solidification mode and temperature, experiments by a small-scale continuous casting system were carried out to determine the temperature in the strip of Sn-Bi alloy with low melting temperature. Moreover, a simulation method for the stress and deformation with a free boundary was developed by employing an elastic-viscoplastic constitutive relation relevant to describing both solid and liquid states, and the thickness of the strip along the free boundary was calculated and compared with the measured thickness.
