A machine for manufacturing continuous bars of nonferrous metal by continuous casting includes a movable casting shell, composed of segments arranged in succession, each one having a portion defined, with a bottom and flanks, of the casting shell, and open on the sides directed toward the contiguous segments. The contiguous segments are movable along a closed path that has a substantially rectilinear portion at the casting region. Along the portion, the segments are substantially aligned and define a portion of the casting shell, with bottom and flanks, which is continuous, substantially rectilinear and closed, for at least one portion of the path downstream of the casting region, by a closure component.

The current invention is directed to a medical implant made of bulk-solidifying amorphous alloys and methods of making such medical implants, wherein the medical implants are biologically, mechanically, and morphologically compatible with the surrounding implanted region of the body.

A mold flux for continuous casting has a base material composition containing 25 to 60 mass % of CaO, 15 to 45 mass % of SiO.sub.2, 5 to 25 mass % of F, 0.2 to 1.0 mass % of S, and 0 to 20 mass % of a total of Li.sub.2O, Na.sub.2O, and K.sub.2O, and in the base material composition, f(1) is 0.90 to 1.90, f(2) is 0.10 to 0.40, f(3) is 0 to 0.40, and a total of CaO, SiO.sub.2, F, S, Li.sub.2O, Na.sub.2O, and K.sub.2O is 90 to 100 mass %.

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.

Casting plates constructed for facing the casting orifice of a metallurgical vessel are provided with a metallic casing. The casting plates and metallic casing are provided with a protrusion configured to interact with a detector. The casing has a main surface with an opening, and two substantially longitudinal bearing surfaces. The protrusion extends from the casing in a direction substantially parallel to the longitudinal bearing surfaces. The protrusion is formed by a ramp having an inclined portion.
