MOLTEN METAL HOLDING FURNACE FOR LOW PRESSURE CASTING

摘要

PROBLEM TO BE SOLVED: To circumvent deterioration in casting quality by preventing the released air bubbles from flowing into the molten metal to be injected into a mold when pressurized gas entering into the material constituting a molten metal container of the molten metal holding furnace for low pressure casting is discharged as bubbles into the molten metal.;SOLUTION: A plate member made of a material having a porosity lower than that of the molten metal container is disposed at the bottom of the molten metal container substantially directly beneath the outlet.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
