To provide a method for stably producing a titanium-clad steel sheet with well flantness and thin thickness by using an existing steel sheet hot rolling process.
A steel of ≤0.01 wt.% C as a base material and a titanium or a titanium alloy as a clad material are used, the base material and the clad material are lapped, a stripping material is spread on the surface of the clad material, after a sacrificial material of similar to the base material is lapped on the clad material after spreading the stripping material or after the base material and the clad material are lapped in order, the circumference is welded in a vacuum of ≤10-3 Torr and a slab is produced, this slab is heated to ≤1000°C, in the time of hot rolling with the total draft of ≥85%, this is rough-rolled so as to be made ≥5% of first pass draft, finish-rolled in ≥700°C, and wound up at ≥65°C, the sacrificial material or two clad steel sheets are stripped from the clad steel sheet after winding, and the shape is straightened.
