The invention discloses a method for rolling a pure titanium strip by using a Sendzimir 20-high mill. The method comprises the steps of (1) profile control achieved by designing roll system configuration; (2) thickness control including the step of correcting correction coefficients of each thickness interval of a thickness gauge by using titanium plate thickness standard plates; and (3) surface control including the step of strictly controlling strip steel temperature and rolling technology parameters when rolling is carried out. By utilization of an existing stainless steel 20-high Sendzimir mill, through thickness gauge adjustment, roll system configuration and rolling technology control, satisfactory profile, thickness, surface and yield are obtained.
