Abstract
PURPOSE: To produce high guality watch case by forming case prototype long- length casting relieved of impurities by melting and arc-remelting raw materials to obtain the material.
CONSTITUTION: Specified raw material, such as nickel base alloy and stainless steel, is melted in a vacuum high frequency induction heating furnace to make crude bar. This crude bar is remelted by discharge in vacuum atmosphere or argon gas atmosphere or the like and is collected in a vessel. At the same time, by pouring the molten metal into a water-cooled mold placed underneath the vessel, impurities and inclusions are suspended up in the vessel, and specified case prototype long- length material 1 for watch case is formed by casting. When the material 1 is cut to a specified thickness by linear discharge electrolysis, case prototypes 3... without containing impurities and inclusions are manufactured. Thus, by cutting, grinding and pressing the prototypes 3..., high quality watch cases without scars due to impurities and inclusions may be obtained
