Abstract：In order to explore the use of the existing steel strip continuous annealing line for the possible production of cold rolled titanium strips，according to the condition of a domestic strip continuous annealing furnace，a finite element model of the elastic- plastic deformation of titanium strips in the annealing furnace was established based on the ABAQUS simulation platform. The simulation results showed that the furnace roller shape，initial flatness defect, and boundary tension may be the major effect factors for the transverse stress distribution of titanium strips. The transverse stresses of titanium strips became more and more nonuniform on crown roller，single taper roller，and double taper roller. The initial flatness defects，e.g. edge wave and middle wave，caused the transverse stress distribution to be more uneven. The boundary tension played a relative slight effect on the transverse stress distribution of titanium strips. It had the reference value in the study can be used in the design of technological requirements on the furnace roller shape and initial flatness defects of titanium strips.
