Title: Crucible furnace
Inventor: OKADA TAMIO
IPC: F27B14/16
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a crucible furnace capable of preventing the temperature of a molten metal from being lowered due to the supply of ingots or foreign materials from being dragged. SOLUTION: A crucible furnace 1 comprises a crucible 6, an upper surface opened box 9 suspended therein and an inlet port 11 for a molten metal formed in at least one of the bottom or the lower part of the side wall of the box 9. Thus, a problem of the fall of pump-out temperature upon fall of the temperature of the molten metal resulting from the supply of ingots 14 can be solved. Further, since foreign materials do not enter the molten metal, the cause of a trouble such as a hard spot is not generated. Thus, the yield of products can be improved, an idle time can be decreased and the pump-out frequency of the molten metal can be increased, hence, the productivity can be rapidly improved.

A signal is sent to controller and the operator is notified of the fact that ink amount in the tank 7 reduces by means of sound or light. The given negative pressure value is determined the stiffness of the flexible film 203, the spring constant of a spring 206, and the interval between the electrodes. A valve 700 provided for the opened part 11 to the open air is closed when the residue of in is detected and opened in the other cases by signals from the controller. The variations in pressures in the sensor 6 with change of temperature can thus be climinated.
