20110011499 | METHOD AND DEVICE FOR HARDENING PROFILES - The invention relates to a method for producing hardened profiles, in particular hardened open profiles, wherein the component is at least partly heated to above the austenitizing temperature of the base material and after heating the component is cooled at a rate above the critical hardening rate, the energy necessary for the heating being introduced at least partly by induction, wherein free edges are provided in the component to adjust a temperature or hardness gradient over the cross section of the component, the size, type and extension of the edges being set for a desired degree of hardness and/or hardness gradient. | 01-20-2011 |
20120012232 | METHOD AND APPARATUS OF FRICTION WELDING TO INCREASE TENSILE STRENGTH OF WELDED WORKPIECE - A friction welding method includes a step of friction welding a first workpiece and a second workpiece together by pressing the first workpiece against the second workpiece relatively while rotating the two workpieces relatively, and a step of annealing the friction welded workpiece at a position adjacent to a welded portion thereof with high frequency induction heating. A friction welding apparatus is provided for friction welding a first workpiece and a second workpiece together by pressing the first workpiece against the second workpiece relatively while rotating the two workpieces relatively. The friction welding apparatus includes a high frequency induction heater for annealing the friction welded workpiece at a position adjacent to a welded portion thereof with high frequency induction heating. | 01-19-2012 |
20130000795 | Amorphous Core Annealing Method - There is provided an amorphous core annealing method in which the annealing temperature distribution within an iron core is regulated so that deterioration in the magnetic properties, which is caused by unevenness of the annealing temperature within the core, can be suppressed, and the annealing time can be shortened. In order to regulate the annealing temperature distribution within the amorphous core at the annealing time, a heater functioning as a heat source is held between laminated thin-film amorphous materials of an iron core, and annealing is performed. By uniformly regulating the annealing conditions within the core, deterioration in the magnetic properties, which is caused by unevenness of annealing, can be suppressed to a minimum. Also, an iron core of a special specification, for example, a core having a low core loss, or a core having a high magnetroresistance, can be manufactured by using different annealing conditions within the iron core. | 01-03-2013 |
