METHOD FOR MAINTAINING CONSTANT OUTFLOW RATE OF MOLTEN METAL IN LADLE

Title:

METHOD FOR MAINTAINING CONSTANT OUTFLOW RATE OF MOLTEN METAL IN LADLE

Document Type and Number:

Japanese Patent JPS6199560

Kind Code:

A

Abstract:

PURPOSE: To maintain the specified outflow rate of a molten metal by evacuating the inside of a ladle when the height of the molten metal in the ladle is higher than a reference height and pressurizing the same when the height is lower than the reference height.

CONSTITUTION: The optional height of the molten metal in the ladle is determined as the reference height and the height of the molten metal in the ladle during outflow is detected. The detected height and the reference height are compared and the molten metal is evacuated until both heights are made equal when the detected height is larger than the reference height. The molten metal is pressurized in the opposite case so that always specified outflow is executed. The degassing in the molten metal is executed by the evacuation.
