<p><P>PROBLEM TO BE SOLVED: To improve operationality and workability for workers during the casting by using a metal material or the like he/she has never used. <P>SOLUTION: When the worker enters selected information on a liquid phase temperature of the metal used for the casting, the amount of the metal, and an investment material of a cast mold in an operation part 42, a program creating part 41 automatically creates an operation program including a temperature program for a heating furnace and pressurizing timing during the casting based on the entered information, and a control part 40 controls a heating temperature by a heater 14 and the opening and closing of a gas introducing valve 50 in accordance with the operation program. Since the liquid phase temperature of the metal is described in an instruction book provided by a metal manufacturer, and the amount of the metal is the weight of the metal actually housed in the crucible by the worker, they are easily acquired. Consequently, since the entry of these items imposes a slight burden on the worker compared to the setting of various temperatures and time required for a conventional device, the workability is greatly improved. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
