The present invention, the breakdown process, such as bungoe rolling or also calibrate without going through the process, and can be sent to a general-purpose hot rolling mill which produces the strip-like coil, can also suppress generation surface flaws in the hot-rolled strip-like coil according to which titanium slabs and for hot rolling the solvent method and a rolling method for titanium slab casting to provide, crystal toward the inside from the surface layer the growth direction (solidification direction) and the casting direction (longitudinal direction) and a direction parallel to the slab, angle θ is 45 to 90 ° forming, and θ is more than 70 to 10㎜ and characterized by having a surface layer of tissue 90 °, and the inclination α of the titanium on the C-axis direction from the slab blood rolling surface side of the rolling plane P a layer of crystal grains in the range of 35 to 90 ° from the normal direction and being formed at least 10㎜. Art titanium slabs, using the electron-beam furnace can be by solvent casting to the pull-out speed 1.0㎝ / min or more.
