METHOD OF PREHEATING A SET OF SHELL MOLDS FOR LOST-WAX CASTING |
| 摘要 |
The invention relates to a method of preheating a set of N shell molds (12) for lost-wax casting, the method comprising the following successive steps: individually charging shell molds into n unit electric furnaces (100), each of which has previously been preheated to an initial loading temperature; starting a predefined preheating cycle for each shell mold charged in the unit electric furnaces, with a preheating cycle comprising raising the temperature of the furnace in compliance with a predefined ramp up to a predetermined setpoint temperature, and holding the furnace at the setpoint temperature for a predetermined duration; and at the end of each preheating cycle, unloading the shell mold in question and repeating the two preceding steps for another non-preheated shell mold. |
