The invention discloses a titanium steel composite board production method. The method comprises the steps that a steel plate is rolled on a hot mill to be 6 mm thick, and air cooling is carried out on the steel plate, the surface of the steel plate obtained after air cooling is carried out and the surface of the titanium plate are cleaned thoroughly, and then the steel plate is rolled by 2-5 passes under the temperature condition being 850 DEG C; the steel plate comprises chemical components being 0.16% of C, 0.61% of Mn, 0.2% of Si, 0.23% of S, 0.019% of P, 0.3% of Cr, 0.3% of Ni, 0.3% of Cu, 0.08% of As, and the balance Fe; according to the chemical components, the titanium plate comprises 0.08% of Fe, 0.08% of O, 0.05% of C, 0.0112% of N, 0.01% of Si, 0.01% of H and the balance Ti. The chemical components of the titanium plate and the steel plate are strictly controlled, the phenomenon that the composite board is mixed with impurities is effectively avoided, and the method is simple and low in production cost.
