    • A titanium slab for hot rolling comprised of a titanium slab obtain by smelting commercially pure titanium, wherein even if the breakdown process is omitted, the strip shaped coil after hot rolling is excellent in surface properties and a method of smelting that titanium slab are provided. The titanium slab according to the present invention is a titanium slab for hot rolling obtained by smelting commercially pure titanium including the β phase stabilizing element Fe, wherein the formation of coarse β phases is suppressed by making the average Fe concentration down to 10 mm from the surface layer of the surface which corresponds to at least the rolling surface of the titanium slab 0.01 mass % or less. A titanium slab obtained by smelting commercially pure titanium can be obtained by cooling until the surface becomes the β transformation point or less, then reheating it to the β transformation point or more, and gradually cooling from the slab surface layer.
    • 用于热轧的钛板,由通过熔融商业纯钛获得的钛板获得,其中即使省略击穿工艺,热轧后的带状线圈表面性能也优异,并且提供了钛板坯的熔炼方法。 根据本发明的钛板是用于通过熔融包括β相稳定化元素Fe的商业上纯钛得到的用于热轧的钛板,其中通过使平均Fe浓度从平均Fe浓度降低到10mm来抑制粗β相的形成 对应于钛板的至少轧制面的表面的表层为0.01质量%以下。 通过冷却直到表面成为β相变点以下,然后再加热至β相变点以上,并从板坯表面层逐渐冷却,可以获得通过熔融商业纯钛获得的钛板。
