摘要： Provided is a titanium slab that has little irregularity in size and cracks at corners and can therefore be hot-rolled after melting by an electron beam melting without additional breakdown rolling processes or other corrective processes. A method for producing the slab is also proposed. The titanium slab that is molded directly from an electron beam furnace has a warp of less than 5mm in the direction of thickness of the slab and less than 2.5mm in the lateral direction per 1000mm length of the slab. In a method of melting the titanium slab to be hot-rolled, molten metal is poured into a mold having a rectangular shape that is placed inside an electron beam furnace from a gate provided on the shorter side wall of the rectangle. Every corner of the rectangular mold is rounded.

摘要： TITANIUM SLAB FOR HOT ROLLING PRODUCED BY ELECTRON-BEAM MELTING FURNACE, PROCESS FOR PRODUCTION THEREOF, AND PROCESS FOR ROLLING TITANIUM SLAB FOR HOT ROLLINGA titanium slab is appropriate for hot rolling, is produced by electron beam melting furnace, has superior linearity so that it can be fed into a hot rolling machine without performing breaking down process or other subsequent correcting process after production, and has good structure having no cracks at the corner parts. A process for production thereof is also provided. The titanium slab is directly produced by a mold of an electron beam melting furnace, and has the deformation of not more than 5 mm for the thickness directionversus the longitudinal direction and deformation of not more than 2.5 mm for the width direction versus the longitudinal direction, both per a length of 1000 mm of the slab. The process for production of this titanium slab for hot rolling has a step of using an electron beam melting furnace in which its rectangular mold has mold walls of a long side and mold walls of a short side, and a step of pouring molten metal from one of the mold walls of a short side. Furthermore, a mold having chamfered parts at the corner parts can be used in the process.Figure 4

摘要： A method of controlling the profile of a sheet material while it is rolled between upper and lower working rolls that can be shifted axially and in opposite directions. The profile of each working roll that varies during the time interval between one changing of the working rolls and another is determined. On the basis of the determined roll profiles, the relationship between the amounts of shifting in the roll position and the configuration of the gap between the upper and lower rolls in the axial direction is determined, so as to determine the amount of shift in the roll position that will provide the smoothest possible configuration for the gap in the axial direction within the area of contact between the work and the working rolls. The upper and lower rolls are shifted axially in accordance with the determination of how to provide the smoothest possible configuration for the gap between rollers.

摘要： PROBLEM TO BE SOLVED: To provide a low elastic β titanium alloy producible by an ordinary melting method for titanium and whose elastic modulus can be controlled to ≤65 GPa, and to provide its production method. SOLUTION: The titanium alloy in this invention has a composition comprising, by mass, 5.0 to 45.0% Nb and 10.0 to 35.0% V, and, if required, further comprising one or two kinds selected from 2.0 to 8.0% Al and 0.05 to 0.30% O, and the balance Ti with inevitable impurities. Further, the titanium alloy contains an α phase by aging heat treatment after solution heat treatment in 3 to 10%. The production method in this invention is characterized in that the above composition is prepared as components, and, if required, solution heat treatment and aging heat treatment are performed instead of annealing after cold working, and, if required, annealing is obviated, and a worked structure is made to remain as well.

摘要： PROBLEM TO BE SOLVED: To automatically start rolling of a billet delivered from the twin drum for cooling after the dummy sheet passes, without imposing unreasonable load on the inline mill. SOLUTION: Before a dummy sheet attached to the leading end of a billet 2 delivered from twin drums 1 passes through an inline mill 3, the roll spacing of the inline mill 3 is widened, and the passing of the dummy sheet is detected by a sheet thickness gauge 16 on the outlet side of the mill and the roll spacing of the inline mill 3 is narrowed to the target position for rolling, thereby making it possible to automatically start the rolling from the point when the leading end portion of the billet reaches the inline mill 3 without imposing unreasonable load on the inline mill 3.
