Abstract

PURPOSE: The above-mentioned apparatus, enabled to carry out vacuum degassing with a simple apparatus and good workability, by putting molten metal in the crucible maintained in keeping warm furnace and degassing the crucible through closed cover.
CONSTITUTION: The coating pattern material 4 is applied on the inner face of the crucible furnace 1 and is dried and then, is charged in the heat insulation furnace 3. Moreover, the crucible cover 6 is placed on the furnace 1 and the hose 10 and the evacuating apparatus 11 are connected with the evacuating tube 9. Next, cooling medium, such as water etc., is passed the cooling jacket 12 and also, the furnace 1 is heated by the heating means 13 and then, the material 4 applied on the inner face of the furnace 1, is completely dried by operating the apparatus 11. Then, the cover 6 is covered after injecting a fixed amount of the molten metal 5 in the furnace 1 and vacuum degassing is carried out by operating the apparatus 11 heating the metal 5 by the means 13.
