摘要： A molten salt electrolyzer having a metal collection chamber, an electrolysis chamber, and two or more electrolytic cell units positioned in the electrolysis chamber. Each electrolytic cell unit has a cathode having an inner space in a prism form; at least one bipolar electrode in a rectangular cylinder form and disposed in the cathode inner space; and an anode in a prism form and disposed in an inner space of the bipolar electrode. At least part of individual planes forming an outer side of the bipolar electrode closest to the cathode faces a plane forming the prism-form inner space of the cathode. At least part of individual planes forming the inner side of the bipolar electrode closest to the anode faces a plane forming the prism of the anode. At least one plane of the cathode constitutes one plane of a cathode of another electrolytic cell unit.

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 θ 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 θ 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 α 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.
