VACUUM FURNACE FOR METAL MELTING OPERATION
Document Type and Number:
Japanese Patent JP3304009
Kind Code:
B2
Abstract:
PURPOSE: To provide a vacuum furnace for metal melting operation having a preheating means capable of performing a preheating operation of a trough within inert gas atmosphere while its clean state is being kept.
CONSTITUTION: In an inclined type vacuum furnace for metal melting operation for inclining a melting furnace and feeding out molten metal, a trough device 6 having a trough 7 for receiving fed-out molten metal, guiding the molten metal toward a molten metal discharging port 12 and fixed against an inclination of the melting furnace near the molten metal discharging port of the melting furnace is installed near the molten metal discharging port, a heater 14 is arranged at the upper part of the trough 7, an electrical current feeding terminal 15 is fixed to a molten metal discharging part 10 fixed against an inclination of the melting furnace of the trough device 6, an electrical energization is applied from the electrical current feeding terminal 15 to the heater 14 is preheated.
