摘要： The present invention provides a titanium slab for hot rolling which can be fed into a general purpose hot-rolling mill for producing strip coil, without passage through a breakdown process such as blooming or a straightening process, and can further suppress surface defect occurrence of the hot-rolled strip coil, and a method of producing and a method of rolling the same, characterized in that in the cast titanium slab an angle ¸ formed by the crystal growth direction (solidification direction) from the surface layer toward the interior and a direction parallel to the slab casting direction (longitudinal direction) is 45 to 90°, and moreover, there is a surface layer structure of 10 mm or greater whose ¸ is 70 to 90°, and further characterized in that a crystal grain layer of 10 mm or greater is formed whose C-axis direction inclination of a titanium ± phase is, as viewed from the side of the slab to be hot rolled, in the range of 35 to 90° from the normal direction of the surface to be hot rolled. The titanium slab concerned is produced using an electron beam melting furnace by casting at an extraction rate of 1.0 cm/min or greater.

摘要： The present invention provides a titanium material for hot rolling that enables reduction of defects occurring on the surface (in the case of a flat material or strip coil, including not only the flat surfaces but also the side surfaces and edges) owing to the hot rolling, and a method of producing the same, particularly to a titanium material for hot rolling enabling omission of an ingot breakdown process, and a method of producing the same, characterized in that it is a titanium material for hot rolling having dimples imparted by cold plastic deformation whose mean value of the heights (Wc) of the undulation profile elements is 0.2 to 1.5 mm and mean value of the lengths (WSm) thereof is 3 to 15 mm, and makes it possible to minimize surface defects occurring in hot rolling even if a process for breaking down the ingot is omitted. The dimples are formed by plastically deforming the surface of the titanium under cold condition using a steel tool having a tip shape of a radius of curvature of 3 to 30 mm or a steel sphere of a radius of 3 to 30 mm.

摘要翻译：本发明提供一种用于热轧的钛材料，其能够减少由于热轧而发生在表面上的缺陷（在扁平材料或带状线圈的情况下，不仅包括平坦表面，而且包括侧面和边缘）及其制造方法，特别涉及能够省略锭分解工艺的热轧用钛材及其制造方法，其特征在于，它是用于热轧的钛材料，其具有由冷塑料赋予的凹坑起伏型材的高度（Wc）的平均值为0.2〜1.5mm，长度（WSm）的平均值为3〜15mm的变形，即使在热轧时发生的表面缺陷也能够最小化省略了用于分解锭的过程。凹陷是通过使用具有3至30mm的曲率半径的尖端形状的钢制工具或半径为3至30mm的钢球而在冷态下使钛的表面发生塑性变形而形成的。
